Refer to the “Create Enhanced FlashCopy Group” on page 3-70 section for more information.
Additionally, optional parameters include the following:
v Setting a repository full policy that defines whether you want to fail writes from the base logical drive
or to delete (purge) Enhanced FlashCopy images.
v
The priority for rollback operations when you want to restore from the Enhanced FlashCopy images.
You can choose the amount of system processing to devote to rollback that ranges from a minimal
impact to host I/O processing to a high impact that reduces host I/O processing.
v
Warning limits for when the repository logical drive is approaching full. The limit is a percentage of
the capacity of the repository logical drive.
v
A minimum number of Enhanced FlashCopy images that you want to delete if you have chosen to
delete the Enhanced FlashCopy images as the method for managing the repository full policy.
v
Enabling and defining a schedule for capturing Enhanced FlashCopy images.
Deleting an Enhanced FlashCopy Image Group
When you delete an Enhanced FlashCopy group the system performs the following actions when an
Enhanced FlashCopy group is deleted:
v
Deletes all existing Enhanced FlashCopy images from the Enhanced FlashCopy group.
v
Deletes the associated repository that exists for the Enhanced FlashCopy group (if selected).
v
Disables all the associated Enhanced FlashCopy logical drives that exist for the deleted Enhanced
FlashCopy images.
To delete the Enhanced FlashCopy group and its associated repositories, use this command:
delete enhancedFlashCopyGroup
["enhancedFlashCopyGroupName"]
deleteRepositoryMembers=TRUE;
If you want to retain the repository logical drives, set the
deleteRepositoryMembers
parameter of the
above command to
FALSE
.
See the “Deleting an Enhanced FlashCopy Image Group” for more information.
Creating an Enhanced FlashCopy Image
To create a new Enhanced FlashCopy image use the
create enhancedFlashCopyImage
command. This
command creates a new Enhanced FlashCopy image in one or more existing Enhanced FlashCopy
groups. Before you can create an Enhanced FlashCopy image, you must first have at least one Enhanced
FlashCopy group into which you can place the Enhanced FlashCopy image.
The only parameters that you need to enter with this command are the names of the Enhanced
FlashCopy groups.
To create an Enhanced FlashCopy Image of Enhanced FlashCopy Group to
enFCGName
, use the following
command:
create enhancedFlashCopyImage
enhancedFlashCopyGroup="
enFCGName";
See the “Create Enhanced FlashCopy Image” on page 3-76 for more information.
