Removing PCIe SSDs From Fluid Cache Pool

To remove a PCIe SSD from a cache pool:

1. In the Server Administrator window, under the system tree, expand Storage to display the controller objects.

2. Expand the PCIe SSD SubSystem object.

3. Expand the Enclosure (Backplane) object.

4. Expand the Physical Devices object.

The Physical devices on PCIe SSD SubSystem page is displayed with the available list of physical disks.

5. 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.

6. 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?

7. 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, Storage Management 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.

PCIe SSD SubSystem Health

Indicates the roll-up health status of physical devices. The individual health status of the physical devices appears at the

respective level.
