Alphabetical list of commands
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.
Syntax
clear cache [volume
volume
]
Parameters
volume
volume
Optional. Name or serial number of the volume whose cache data should be cleared. For volume
syntax, see
Command syntax
on page 22. If this parameter is omitted, the command clears any
unneeded orphaned data for volumes that are no longer online or that no longer exist.
Example
Clear unwritable cache data for volume
V1
from both controllers:
# clear cache volume v1
Success: Command completed successfully - If unwritable cache data existed, it
has been cleared. (2012-01-18 14:21:11)
