To remove a schedule, use the
create EnhancedFlashCopyGroup
command or the
create
consistencyGroup

enableSchedule
parameter to
FALSE
. The
enableSchedule
parameter set to
FALSE
turns off the schedule, not the creating of Enhanced FlashCopy images.
Syntax
The following command will create a schedule for creating Enhanced FlashCopy images for
enhancedFlashCopyGroupName Enhanced FlashCopy group two times a day, on Mondays and Fridays of
the week, starting with the first image at 2:00 AM and the second image 720 minutes after the first image;
the start date is May 20th, 2012 with no end date:
create enhancedFlashCopyGroup
userLabel="enhancedFlashCopyGroupName"
purceLogicalDrive="BaselogicaldriveName"
repositoryLogicalDrive="repos_0001"
repositoryFullPolicy= purgeEnhancedFlashCopyImages
rollbackPriority=highest
repositoryFullLimit=50
enableSchedule=TRUE
schedule startDate=05:20:12

Deleting an Enhanced FlashCopy Image Group (with options)
When you delete an Enhanced FlashCopy image from an Enhanced FlashCopy group, the system
performs the following actions:
v
Deletes the Enhanced FlashCopy image from the storage subsystem.
v
Releases the repository’s reserve space for reuse within the Enhanced FlashCopy group.
v
Disables all the associated Enhanced FlashCopy logical drives that exist for the deleted Enhanced
FlashCopy image.
For an Enhanced FlashCopy consistency group you can delete:
v A single Enhanced FlashCopy image.
v
Multiple Enhanced FlashCopy images that have the same sequence number and creation timestamp.
When an Enhanced FlashCopy image(s) is deleted from an Enhanced FlashCopy consistency group, the
system performs the following actions:
v
Deletes the Enhanced FlashCopy images from the storage subsystem.
v
Releases the repository’s reserve space for reuse within the an Enhanced FlashCopy consistency group.
v
Moves any member logical drive, associated with the deleted Enhanced FlashCopy image(s), to a
Stopped state.
v
Disables the member Enhanced FlashCopy logical drives associated with the deleted Enhanced
FlashCopy image(s).
To delete the Enhanced FlashCopy image, use this command:
delete EnhancedFlashCopyImage
Optionally you can choose to keep a number of Enhanced FlashCopy images with either of these
parameters:
v deleteCount
– This parameter deletes the oldest Enhanced FlashCopy image first and continues to
delete the Enhanced FlashCopy images in the order of creation, until reaching the number that you
enter. If the number that you enter is greater than the number of Enhanced FlashCopy images, then all
of the Enhanced FlashCopy images are deleted.
