To increase the size of an Enhanced FlashCopy logical drive repository logical drive using existing
repository of
repos_xxxx
, use this command:
v
set EnhancedFlashCopyLogicalDrive ["EnhancedFlashCopyLogicalDriveName"]
increaseRepositoryCapacity
repositorylogicaldrives=(repos_xxxx)
v
To increase the size of an Enhanced FlashCopy group repository logical drive using existing repository
of
repos_xxxx
use this command:
set EnhancedFlashCopyGroup ["EnhancedFlashCopyGroupName"]
increaseRepositoryCapacity
repositorylogicaldrives=(repos_xxxx)
Note:
v
repositoryLogicalDrive
- Can be either the name of existing repository like
repos_xxxx
or the name of
the subsystem or disk pool that the Enhanced FlashCopy group resides, and the capacity of the
repository, for example
(subsystemName capacity=00)
v
repositoryFullLimit=percentValue
- Repository capacity at which you will receive a warning that the
Enhanced FlashCopy repository logical drive is nearing full capacity.
Decreasing the Size of a Repository Logical drive
If a repository logical drive has more capacity than is needed, you can reduce the capacity of the
repository logical drive by removing member logical drives from the end of its concatenated set. A
repository logical drive must always retain at least one member after such a reduction. The member
logical drives that are removed in such an operation are effectively “detached” from the repository logical
drive, thus reducing the repository logical drive capacity. The detached logical drives can then be reused
to provide additional capacity for the same or a different repository logical drive.
You can reduce the storage capacity of an existing repository logical drive for the following storage
objects:
v
Enhanced FlashCopy group
v
Enhanced FlashCopy logical drive
v
Consistency group member logical drive
v
Consistency group member Enhanced FlashCopy logical drive
Prerequisites
You cannot decrease the storage capacity of the overall repository if one of these conditions exists:
v
The overall repository contains only one repository member logical drive.
v
If there are one or more Enhanced FlashCopy images associated with the overall repository.
v
If an Enhanced FlashCopy logical drive or a consistency group member Enhanced FlashCopy logical
drive is disabled.
Guidelines
v
You can only remove repository member logical drives only in the reverse order that they were added.
v
An overall repository must have at least one repository member logical drive.
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 logical drive.
v
When you decrease capacity for an Enhanced FlashCopy logical drive or a consistency group member
Enhanced FlashCopy logical drive, the system automatically migrations the logical drive to a Disabled
state.
