Deleting an Enhanced FlashCopy Image Logical drive
If you no longer need an Enhanced FlashCopy logical drive, you can delete the logical drive using this
command:
delete EnhancedFlashCopylogicalDrive
When you delete an Enhanced FlashCopy logical drive the system performs the following actions:
v
Deletes all existing links with the Enhanced FlashCopy image.
v
Deletes the associated repository that exists for the Enhanced FlashCopy group (if selected).
If you want to retain the repository members, set the
deleteRepositoryMembers
parameter to
FALSE
.
Changing the Size of a Repository Logical drive
You can increase or decrease the size of a repository logical drive.
Increasing the Size of a Repository Logical drive
Typically, you use increase capacity when you receive a warning that the repository is becoming full. You
can increase the repository capacity by performing one of these tasks:
v
Adding one or more existing repository logical drives
v
Creating a new repository logical drive using free capacity that is available on an subsystem or disk
pool.
If any subsystem or disk pool does not have free capacity, you can add unconfigured capacity in the form
of unused drives to an subsystem or disk pool.
Prerequisites
You cannot increase the storage capacity of a repository logical drive if one of these conditions exists:
v
The logical drive that you want to add does not have an Optimal status.
v
Any logical drive in the subsystem or disk pool that you want to add is in any state of modification.
v
The subsystem or disk pool does not have any free capacity.
v
The subsystem or disk pool does not have any unconfigured capacity.
v
Eligible logical drives are not available.
Guidelines
v
Each of the individual logical drives in the overall repository must have the same T10PI settings as the
associated base logical drive for the storage object. For example, if a base logical drive for a storage
object is T10PI enabled, then the associated overall repository must be T10PI enabled.
v
Ensure that a base logical drive and each of the individual logical drives in the overall repository have
the same Quality of Service (QoS) attributes, specifically for the following characteristics:
– RAID Level. A repository in a disk pool is considered to have a matching RAID Level for any base
logical drive on an subsystem, regardless of the base logical drive’s actual RAID Level. However, a
repository on an subsystem is considered to have a matching RAID Level only if that RAID Level is
identical to the RAID Level of the base logical drive.
– Drive Type. A match requires that the base logical drive and the repository logical drive reside on
either an subsystem or disk pool with identical drive type attributes.
v
You cannot increase or decrease the repository capacity for an Enhanced FlashCopy logical drive that is
read-only because it does not have an associated repository. Only Enhanced FlashCopy logical drives
that are read-write require a repository
