Delete Performance Read Cache - IBM System Storage DS3000 Programming Manual

Parameters
Parameter
allLogicalDrives
logicaldrive or logicaldrives
removesubsystem
force
schedule
retainRepositoryMembers
Notes
When you use the allLogicalDrives parameter, this command deletes logical drives until all of the
logical drives are removed or until an error is encountered. If an error is encountered, this command does
not try to delete the remaining logical drives. Deleting logical drives from different subsystems is
possible. All of the subsystems that become empty are deleted if you set the removesubsystem parameter
to TRUE.

Delete Performance Read Cache

This command deletes the Performance Read Cache. All data in the SSD cache is purged.

Description
This parameter deletes all of the logical drives on a disk
pool.
The name of the logical drive that you want to delete.
You can enter more than one logical drive name. Enclose
the logical drive name in square brackets ([ ]). If the
logical drive name has special characters, you also must
enclose the logical drive name in double quotation marks
(" ").
Deleting the last logical drive in an subsystem does not
delete the subsystem. You can have a standalone
subsystem (minus any logical drives). To remove the
standalone subsystem, set this parameter to TRUE. To
keep standalone subsystems intact, set this parameter to
FALSE.
Use this parameter to force the immediate deletion of a
logical drive even if the controllers are performing other
operations. To immediately force the deletion of a logical
drive, set this parameter to TRUE. To wait until the
controllers have finished performing other operations, do
not use this parameter or set this parameter to FALSE.
When you delete a thin logical drive, the associated
repository logical drive is deleted by default. However,
when the retainRepositoryMembers is set to TRUE, the
repository logical drive is retained. For normal logical
drives, this parameter has no effect.
