Dedicated Hot Spare Considerations
The following considerations apply to dedicated hot spares:
- Considerations for RAID 10, RAID 50, and RAID 60
— If you have created a RAID 10 or RAID 50 virtual disk that does
not fully consume its member physical disks, then you cannot assign
a dedicated hot spare to the RAID 10 or RAID 50 virtual disk. Storage
Management does not allow you to create RAID 10 and RAID 50 virtual
disks from partial physical disks. You therefore do not encounter
this situation if you use Storage Management to create your virtual
disks. If, however, the RAID 10 or 50 virtual disk was created using
another application and if it does contain partial physical disks,
then you can assign a dedicated hot spare to the virtual disk. NOTE: For PERC H700 and PERC H800 controllers, you can assign a dedicated hot spare to RAID 10, RAID 50, and RAID 60.
- Considerations for Multiple Dedicated Hot Spares — From Storage Management version 3.1 onwards, you can assign more than one dedicated hot spare to a virtual disk.
