Reduce Disk Pool Capacity
Description
This command reduces the capacity of the disk pool by logically removing the physical disks from the
pool. This command uses the Dynamic Capacity Reduction (DCR) feature, which enables you to remove
selected physical disks from a disk pool and re-use the removed physical disks as needed.
The maximum number of physical disks that you can remove from a disk pool in a single DCR operation
is 12. You cannot reduce the disk pool to below the minimum disk pool size.
Syntax
set diskPool [diskPoolName]
removeDrives=(enclosureID1,drawerID1,slotID1
... enclosureIDn,drawerIDn,slotIDn)
Parameters
Parameter Description
diskPool
The name of the disk pool for which you want to
reduce capacity. Enclose the disk pool name in
square brackets ([ ]).
removeDrives
The physical disks that you want to remove from
the disk pool. For dense expansion enclosures,
specify the enclosure ID value, the drawer ID value,
and the slot ID value for each physical disk that you
want to remove. For non-dense expansion
enclosures, specify the enclosure ID value and the
slot ID value for each physical disk that you want to
remove. Enclosure ID values are 0 to 99. Drawer ID
values are 0 to 4. Slot ID values are 0 to 31.
Enclose the enclosure ID values, the drawer ID
values, and the slot ID values in square brackets
([ ]).
Notes
Each disk pool name must be unique. You can use any combination of alphanumeric characters,
underscore (_), hyphen(-), and pound (#) for the user label. User labels can have a maximum of 30
characters.
You might want to remove selected physical disks from a disk pool if you need to create a separate group
or remove unneeded capacity from the storage array. The removed physical disks become unassigned
