Clear Cache - HP P2000 Reference Manual

clear cache

Description Clears unwritable cache data from both controllers. This data cannot be written to disk because it is
associated with a volume that no longer exists or whose disks are not online. If the data is needed,
the volume's disks must be brought online. If the data is not needed it can be cleared, in which case
it will be lost and data will differ between the host and disk. Unwritable cache is also called orphan
data.
You can clear unwritable cache data for a specified volume or for all volumes.
