Physical Disks

Physical disks reside within an enclosure or are attached to the controller. On a RAID controller, physical disks are used to create virtual disks.

Guidelines to Replace a Physical Disk

A replacement disk may not always be the same model as the physical disks in the storage enclosure. Use the following guidelines when replacing a disk:

A drive within an array may be replaced with a drive of equal or greater capacity.
Consider the bus speed while replacing a drive. Dell supports replacing drives with equal or greater bus speeds within the same array. You can use both 3-GB and 6-GB drives in the same array. It is not recommended to replace a 6-GB drive with a 3-GB drive. Although it is fully functional, the performance could be impacted. Dell supports replacing 3-GB drives with 6-GB drives. This occurs more frequently as legacy parts are depleted and warranty service is required.
Also consider the RPM while replacing a drive. Dell supports replacing drives with equal or greater spindle speeds within the same array. You can use both 10000 RPM and 15000 RPM drives in the same enclosure. It is not recommended to replace a 15000 RPM drive with a 10000 RPM drive. Although it is fully functional, the performance could be impacted. Dell supports replacing 10000 RPM drives with 15000 RPM drives. This scenario occurs while replacing parts from service inventory due to part unavailability.
Dell supports SAS and SATA drives on the same backplane but not within the same Virtual Disk.
Dell supports Solid State Disks and Hard Disk Drives on the same backplane but not within the same Virtual Disk.
NOTE: With the exception of combining SAS,SATA,SCSI, and SSD drives, Dell supports upgrades and not downgrades.

Add a New Disk to Your System

1 Install or attach the new physical disk (or disks). For more information, see the documentation that came with the disk.
2 Do one of the following depending on the controller technology. For more information, see RAID Controller Technology: SCSI, SATA, ATA, and SAS.

For SCSI, SATA, and ATA Controllers

a Select the controller to which the disk is attached and click the Information/Configuration tab.
b Execute the Rescan task.

The new disk should be displayed in the tree view after the rescan. If the new disk is not displayed, restart the computer.

For SAS Controllers

a Check the Alert Log for an alert verifying that the system has identified the new disk. You may receive alert 2052 or 2294. For information on Alert Messages, see the Dell OpenManage Server Administrator Messages Reference Guide at support.dell.com/manuals.
b Refresh the display by clicking Refresh or by changing screens.
NOTE: Clicking the Refresh button in the right pane refreshes only the right pane. To view the new physical disk in the left pane tree view, click the system name displayed at the top of the left pane, or select View --> Refresh from the browser's menu bar.

The new physical disk should be displayed in the tree view after refreshing the display. If the new disk is not displayed, restart the computer.

If you want to include the new disk in a virtual disk, see Virtual Disk Considerations for Controllers or Virtual Disk Considerations for CERC SATA1.5/6ch, and CERC SATA1.5/2s Controllers.

How to Avoid Removing the Wrong Disk

You can avoid removing the wrong disk by blinking the LED display on the disk that you want to remove. For information on blinking the LED display:

See Blink and Unblink (Physical Disk) to blink the LED display on a physical disk.
See Blink and Unblink (Virtual Disk) to blink the LED display on all physical disks included in a particular virtual disk.

If you have already removed the wrong disk, see Recovering from Removing the Wrong Physical Disk.

Replacing a Physical Disk Receiving SMART Alerts

SMART alerts are messages predicting that a disk may fail in the near future. If a physical disk is receiving SMART alerts, you should replace the disk. Use the following procedures to replace a disk receiving SMART alerts.

If the disk is part of a redundant virtual disk:

1 Select the redundant virtual disk that includes the physical disk that is receiving SMART alerts and perform the Check Consistency task. For more information, see Check Consistency.
CAUTION: To avoid potential data loss, you should perform a check consistency before removing a physical disk that is receiving SMART alerts. The check consistency verifies that all data is accessible within the redundant virtual disk and uses the redundancy to repair any bad blocks that may be present. In some circumstances, failure to perform a check consistency can result in data loss. This may occur, for example, if the physical disk receiving SMART alerts has bad disk blocks and you do not perform a check consistency before removing the disk.
2 Select the disk that is receiving SMART alerts and execute the Offline task.
3 Manually remove the disk.
4 Insert a new disk. Make sure that the new disk is the same size or larger as the disk you are replacing. On some controllers, you may not be able to use the additional disk space if you insert a larger disk. For more information, see Virtual Disk Considerations for Controllers. After you complete this procedure, a rebuild is automatically initiated because the virtual disk is redundant.

If the disk is not part of a redundant virtual disk:

1 Back up data from the virtual disk.
2 Delete the virtual disk.
3 Replace the disk that is receiving SMART alerts.
4 Create a new virtual disk. Make sure that the new virtual disk is the same size or larger than the original virtual disk. For controller-specific information on creating virtual disks, see Virtual Disk Considerations for Controllers and Virtual Disk Considerations for CERC SATA1.5/6ch, and CERC SATA1.5/2s Controllers.
5 Restore the backed up data from the original virtual disk onto the newly created virtual disk.

Physical Disk Properties

The following table describes properties that may be displayed for physical disks depending on the controller.

Table 9-1. Physical Disk Properties

Property

Definition

Status

These icons represent the severity or health of the storage component.

Normal/OK

Warning/Non-critical

Critical/Fatal

For more information, see Storage Component Severity.

Power Status

The following status of the physical drives. These statuses are present only for H700 and H800 controllers. These icons are not present in the Physical Disk for Virtual Disk page.

Spun Down

Transition

Spun Up

The physical drive is in the spun down state. Only hot spare and unconfigured disk can be in spun down state if no activity happens on the drives for a specified interval of time.

The physical drive is changing from the spun down state to spun up state.

The physical drive is in the spun up state.

Name

This property displays the name of the physical disk. The name is comprised of the connector number followed by the disk number.

State

This property displays the current state of the physical disk.

Ready—The physical disk is functioning normally. If the disk is attached to a RAID controller, Ready state indicates that the disk is available to be used by a virtual disk. When the physical disk is used in a virtual disk, the state changes to Online.

Online—The physical disk is part of a virtual disk and is functioning normally. See Online and Offline for more information.

Degraded—The physical disk has encountered a failure and is operating in a degraded state.

Failed—The physical disk has encountered a failure and is no longer functioning. This state is also displayed when a physical disk that is part of a redundant virtual disk has been taken offline or deactivated. See Online and Offline for more information.

Offline—The physical disk has failed or contains dead segments. Check to see whether the Remove Dead Segments task appears on the physical disk drop-down menu. If it does, perform a Rescan Controller and then do a Remove Dead Segments for the physical disk. If the Remove Dead Segments task is not displayed, then the physical disk cannot be recovered. See Considerations for CERC SATA1.5/6ch and CERC SATA1.5/2s Controllers When Physical Disks are Shared by Redundant and Non-Redundant Virtual Disks for related information.

On the PERC 5/E controller, the Offline state indicates that the disk is included in a virtual disk, but it is not receiving I/O. This may occur when a user has set the disk to Offline. See Online and Offline for more information.

 

Rebuilding—Data from a redundant virtual disk is currently being rebuilt onto the physical disk.

Incompatible—The physical disk is not suitable for a rebuild. The physical disk may be too small or it may be using an incompatible technology. For example, you cannot rebuild a SAS disk with a SATA disk or a SATA disk with a SAS disk.

Removed—The physical disk has been removed. This state only applies to physical disks that are part of a virtual disk.

Clear—The Clear task is being performed on the physical disk. A physical disk may also display the Clear state if the physical disk is a member of a virtual disk that is being slow initialized. For more information, see Clear Physical Disk and Cancel Clear and Format and Initialize; Slow and Fast Initialize.

SMART Alert Detected—A SMART alert (predictive failure) has been detected on the physical disk. The physical disk may fail and should be replaced. This state applies to physical disks attached to non-RAID controllers.

Unknown—The physical disk has failed or is in an unusable state. In some cases the physical disk can be returned to a usable state by performing an Initialize task. If the Initialize task does not appear on the physical disk drop-down menu, then this disk cannot be recovered.

Foreign—The physical disk has been moved from another controller and contains all or some portion of a virtual disk (foreign configuration). A physical disk that has lost communication with the controller due to a power loss, faulty cable or other failure event may also display the Foreign state. See Foreign Configuration Operations for more information.

Unsupported—The physical disk is using an unsupported technology or it may not be certified by Dell. The physical disk cannot be managed by Storage Management.

Replacing—A Replace Member Disk task is being performed on the physical disk. For more information, see Replace Member Disk and Revertible Hot Spare.

NOTE: You can cancel the copying of data at any time during the execution of this task.
 

Non-RAID—Non-RAID disks are exposed to the operating system unlike unconfigured good disks and this enables usage of disk in direct pass-through mode. Maximum number of non-RAID disks that can be supported on H310 controller are 64.

You can do the following on this disk:

Identified as locate option.
Execute blink or unblink operation.
Select as a bootable device.

You cannot do the following on the disk:

Force disk offline or online.
Select as part of a virtual disk.
Assign a hot spare.
Choose as source or target for rebuild, copyback, replace member, or reconstruct.
Spun down to save power.
Select as a bootable device.

Capacity

This property displays the full capacity of the disk.

Certified

This property displays whether or not the physical disk is certified by Dell.

Failure Predicted

This property displays whether or not the physical disk has received a SMART alert and is therefore predicted to fail. For more information on SMART predictive failure analysis, see Monitoring Disk Reliability on RAID Controllers. For information on replacing the physical disk, see Replacing a Physical Disk Receiving SMART Alerts.

You may also want to review the Alert Log to see whether the physical disk has generated alerts pertaining to a SMART predictive failure. These alerts can assist you in identifying the cause of the SMART alert. The following alerts may be generated in response to a SMART alert:

2094

2106

2107

2108

2109

2110

2111

If no tasks can be performed because of controller or system configuration limitations, then the Tasks drop-down menu displays No Task Available.

Physical Disk Drop-down Menu Tasks:

Blink and Unblink (Physical Disk)
Remove Dead Segments
Assign and Unassign Global Hot Spare
Prepare to Remove
Online and Offline
Initialize
Rebuild
Cancel Rebuild
Clear Physical Disk and Cancel Clear
Revertible Hot Spare
Instant Encrypt Erase
Convert to RAID Capable Disk
Convert to Non-RAID Disk

Blink and Unblink (Physical Disk)

Does my controller support this feature? See Supported Features.

The Blink task allows you to find a disk within an enclosure by blinking one of the light-emitting diodes (LEDs) on the disk. You may want to use this task to locate a failed disk.

On most controllers, the Blink task automatically cancels after a short duration such as 30 or 60 seconds. If you need to cancel the Blink task or if the physical disk continues to blink indefinitely, use the Unblink task.

NOTE: The Blink and Unblink tasks are only supported for hotswap physical disks (disks that reside in a carrier). When using an LSI PCI-e U320 controller, the Blink and Unblink tasks apply to physical disks contained in carriers that can be inserted into a server or an enclosure. If the physical disk is not contained in a carrier but is instead designed to be connected with a SCSI cable (typically a ribbon cable), then the Blink and Unblink tasks are disabled.

Remove Dead Segments

Does my controller support this feature? See Supported Features.

The Remove Dead Segments task recovers disk space that is currently unusable. A dead or orphaned disk segment refers to an area of a physical disk that is unusable for any of the following reasons:

The dead segment is an area of the physical disk that is damaged.
The dead segment is included in a virtual disk, but the virtual disk is no longer using this area of the physical disk.
The physical disk contains more than one virtual disk. In this case, disk space that is not included in one of the virtual disks may be unusable.
The dead segment resides on a physical disk that has been disconnected from and then reconnected to the controller.

Prepare to Remove

Does my controller support this feature? See Supported Features.

Use the Prepare to Remove task to spin down a physical disk so that it can safely be removed from an enclosure or backplane. It is recommended that you perform this task before removing a disk to prevent data loss.

This task causes the lights on the disk to blink. You can safely remove the disk under the following conditions:

Wait for about 30 seconds to allow the disk to spin down.
Wait until you notice the initial blink pattern has changed into a different pattern or the lights have stopped blinking.

A physical disk is no longer in Ready state after doing a Prepare to Remove. Removing the physical disk from the enclosure or backplane and replacing it causes the physical disk to spin up and return to Ready state.

In some cases, a rescan is required for the controller to recognize configuration changes such as the removal of a disk. See Rescan to Update Storage Configuration Changes for more information.

NOTE: This procedure is not available for physical disks that have been assigned as a hot spare or physical disks that are part of a virtual disk. In addition, this procedure is only supported for hotswap physical disks (disks that reside in a carrier).
NOTE: This procedure is not supported on the CERC SATA1.5/6ch, and CERC SATA1.5/2s controllers. For the PERC 4/IM controller, this procedure is only supported on a PowerEdge™ 1855 system.

Initialize

Does my controller support this feature? See Supported Features.

The Initialize task prepares a physical disk for use as a member of a virtual disk.

Physical disks attached to CERC SATA1.5/6ch controllers must be initialized before they can be used. On these controllers, the Initialize task can only be performed once on a physical disk. In some cases a physical disk that is in an Unknown state can be returned to a usable state by performing the Initialize task. The Initialize task is not displayed for physical disks that have already been initialized using Storage Management or the BIOS.

CAUTION: This is a data-destructive task. Any virtual disks residing on this physical disk is removed.

Rebuild

Does my controller support this feature? See Supported Features.

Use the Rebuild task to reconstruct data when a physical disk in a redundant virtual disk fails. See Replacing a Failed Disk that is Part of a Redundant Virtual Disk for more information.

Rebuilding a disk may take several hours.

Cancel Rebuild

Does my controller support this feature? See Supported Features.

Use the Cancel Rebuild task to cancel a rebuild that is in progress. If you cancel a rebuild, the virtual disk remains in a degraded state. The failure of an additional physical disk can cause the virtual disk to fail and may result in data loss. It is recommended that you rebuild the failed physical disk as soon as possible.

NOTE: If you cancel the rebuild of a physical disk that is assigned as a hot spare, you must reinitiate the rebuild on the same physical disk in order to restore the data. Canceling the rebuild of a physical disk and then assigning another physical disk as a hot spare does not cause the newly assigned hot spare to rebuild the data. You must reinitiate the rebuild on the physical disk that was the original hot spare.

Assign and Unassign Global Hot Spare

Does my controller support this feature? See Supported Features.

A global hot spare is an unused backup disk that is part of the disk group. Hot spares remain in standby mode. When a physical disk that is used in a virtual disk fails, the assigned hot spare is activated to replace the failed physical disk without interrupting the system or requiring your intervention. When a hot spare is activated, it rebuilds the data for all redundant virtual disks that were using the failed physical disk.

You can change the hot spare assignment by unassigning a disk and choosing another disk as needed. You can also assign more than one physical disk as a global hot spare.

NOTE: On SAS 6/iR controllers, you cannot assign physical disks that have boot partitions, as hot spares.
NOTE: On PERC S100 and S300 controllers, if there is free space available on the global hot spare, it continues to function as a spare even after replacing a failed physical disk. See Considerations for Hot Spares on CERC SATA1.5/6ch, S100, and S300 Controllers.

Global hot spares must be assigned and unassigned manually. They are not assigned to specific virtual disks. If you want to assign a hot spare to a virtual disk (it replaces any physical disk that fails in the virtual disk) then use the Assign and Unassign Dedicated Hot Spare.

NOTE: When deleting virtual disks, all assigned global hot spares may be automatically unassigned when the last virtual disk associated with the controller is deleted. When the last virtual disk of a disk group is deleted, all assigned dedicated hot spares automatically become global hotspares.
NOTE: For PERC H310, H700, H710, H710P, H800, and H810 controllers, if any of the drives you selected is in the spun down state, the following message is displayed: The current physical drive is in the spun down state. Executing this task on this drive takes additional time, because the drive needs to spun up.
CAUTION: The SAS 6/iR controller enables you to assign two physical disks as global hot spare. Assigning a physical disk as a global hot spare on a SAS 6/iR controller is likely to cause data loss from the physical disk. If the system or boot partition resides on the physical disks, it may be destroyed. You should only assign physical disks that do not contain critical data. For more information about global hot spares and the SAS 6/iR, see Global Hot Spare Considerations on a SAS 6/iR.

You should be familiar with the size requirements and other considerations associated with hot spares. For more information, see the following:

Protecting Your Virtual Disk with a Hot Spare
Considerations for Hot Spares on PERC 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, PERC 5/E, PERC 5/i, PERC 6/E, PERC 6/I, and CERC 6/I Controllers
Considerations for Hot Spares on CERC SATA1.5/6ch, S100, and S300 Controllers
Global Hot Spare Considerations on a SAS 6/iR

Online and Offline

Does my controller support this feature? See Supported Features.

The Online and Offline tasks only apply to physical disks that are included in a redundant virtual disk and attached to a PERC 4/SC, 4/DC, 4e/Si, 4e/Di, 4e/DC, or 4/Di controller.

Use the Offline task to deactivate a disk before removing it. Use the Online task to reactivate an offline disk. In some cases, you may want to use the Online task on a failed disk in an attempt to recover data from the disk. For more information, see Using the Physical Disk Online Command on Select Controllers.

NOTE: The Online and Offline tasks are not supported on the PERC 4/IM controller or the CERC SATA1.5/6ch, and CERC SATA1.5/2s controllers.

To online or offline the physical disk:

1 Review the physical disk that must be made online or offline. When making a physical disk offline, be aware that there can be data loss. Back up your data, if necessary. If you want to blink the physical disk, click the Blink button.
2 Click Online or Offline when ready or click Go Back to Previous Page.

To locate this task in Storage Management:

1 Expand the Storage tree object to display the controller objects.
2 Expand a controller object.
3 Expand a Connector object.
4 Expand the enclosure or Backplane object.
5 Select the Physical Disks object.
6 Select Online or Offline from the Available Tasks drop-down menu of the physical disk you want to make online or offline.
7 Click Execute.

Clear Physical Disk and Cancel Clear

Does my controller support this feature? See Supported Features.

Use the clear physical disk task to erase data residing on a physical disk. The Clear task applies to physical disks that are in Ready state and that contain data or that are in Clear state.

NOTE: A physical disk may display the Clear state if it is a member of a virtual disk that is being slow initialized. Performing a Cancel Clear task on the physical disk causes the Slow Initialize task to be cancelled for the entire virtual disk. For more information, see Format and Initialize; Slow and Fast Initialize and Considerations for Slow Initialize.

To clear the physical disk:

1 Review the physical disk to be erased by the Clear task. Be sure that it does not contain necessary data and make a backup if necessary. If you want to blink the physical disk, click the Blink button.
2 Click Clear when you are ready to erase all information on the physical disk. To exit without clearing the physical disk, click Go Back to Previous Page.

To locate this task in Storage Management:

1 Expand the Storage tree object to display the controller objects.
2 Expand a controller object.
3 Expand a Connector object.
4 Expand the enclosure or Backplane object.
5 Select the Physical Disks object.
6 Select Clear from the Available Tasks drop-down menu of the physical disk you want to clear.
7 Click Execute.

Revertible Hot Spare

Does my controller support this feature? See Supported Features.

Use the Revertible Hot Spare task to copy data back from a hot spare to a physical disk.

If the physical disk in a virtual disk fails, the data on the failed disk is copied to the assigned hot spare. If you replace the failed disk with a new physical disk and if you have enabled the revertible hot spare task, the data is copied from the erstwhile hot spare to the new disk.

You can also use the Revertible Hot Spare task to copy data from a physical disk to the hot spare on a predictive failure event.

If Revertible Hot Spare is enabled and the physical disk is SMART-enabled, the controller firmware automatically starts copying data from the SMART-enabled disk in the virtual disk to the hot spare.

NOTE: To use the Revertible Hot Spare task, you should have assigned a hot spare to the virtual disk.
NOTE: If the disk is not SMART-enabled or if the Auto Replace on Predictive Failure option is disabled, the failed disk is not replaced automatically.

To enable Revertible Hot Spare:

1 On the Change Controller Properties page, enable Revertible Hot Spare and Auto replace on predictive failure.
2 Click Apply Changes.

To locate this task in Storage Management:

1 Expand the Storage tree object to display the controller objects.
2 Select a controller object on which you want to enable the revertible hot spare task and select the Information/Configuration tab.
3 From the Controller Task drop down menu, select Change Controller Properties and click Execute.
NOTE: The Rebuild rate for Revertible Hot Spare is the same as defined for the controller.

Instant Encrypt Erase

Does my controller support this feature? See Supported Features.

Use the Instant Encrypt Erase task to erase an encrypted physical disk. This task is available for:

Unconfigured SED drive
Foreign configured encrypted drives
Unconfigured and foreign SED drive even when an Encryption Key is not present in the controller
CAUTION: Instant Encrypt Erase permanently erases all data present on the disk.

To locate this task in Storage Management:

1 Expand the Storage tree object to display the controller objects.
2 Expand a controller object.
3 Expand a Connector object.
4 Expand the enclosure or Backplane object.
5 Select the Physical Disks object.
6 Select Instant Encrypt Erase from the Available Tasks drop-down menu of the physical disk you want to clear.
7 Click Execute.

Convert to RAID Capable Disk

This task enables a disk for all RAID operations.

This task is supported on H310 controllers.

Convert to Non-RAID Disk

This task converts a disk to Non-RAID disk. After converting a disk to non-RAID, the disk is exposed to the operating system unlike unconfigured good disks and this enables usage of disk in direct pass-through mode.

This task is supported on H310 controllers.
