Remove PCIe SSDs From Fluid Cache Pool

To remove a PCIe SSD from a cache pool:
  1. On the left-hand side of the Storage Management page, click Storage > PCIe SSD SubSystem > Enclosure (Backplane) > Physical Devices.

    The Physical devices on PCIe SSD SubSystem page is displayed with the available list of physical disks.
  2. From the list of Tasks corresponding to the physical disk to which you want to remove the PCIe SSD, select the Remove from Cache Pool option.

  3. Click Execute to remove the PCIe SSD. The following message is displayed:

    Device will be removed from Fluid Cache Pool. Are you sure you want to proceed?
  4. Click OK.

    Once the device removal is initiated from the cache pool, any dirty data is moved to the back-end disk. While the data migration is in progress, OMSS displays a transient removal state. After the device is removed from the cache pool, the Part of Cache Pool attribute is Not Enabled.

    When the last but one PCIe SSD is removed from the Fluid Cache pool, the cache pool high availability changes from True to False indicating that the cache pool is Write Through capable only and the operational cache mode for any Fluid Cache disk configured for Write Back changes to Write Through.

    When the last PCIe SSD is removed from the Fluid Cache pool, the operational cache mode for all Fluid Cache disk changes to Pass Through.
