Changing The Settings Of A Snapshot Virtual Disk
Use the Change Snapshot Virtual Disk Settings option to modify the repository settings that were configured when you
created the snapshot virtual disk. You can modify the maximum percentage for the snapshot virtual disk repository to set
a warning when the capacity of a snapshot virtual disk repository reaches the defined percentage.
1.
From the AMW, select the Storage & Copy Services tab.
2.
Select a base virtual disk, and then select Copy Services → Snapshot Virtual disk → Change Settings.
The Change Snapshot Virtual Disk Settings window is displayed.
3.
Modify the repository full settings as required.
4.
Click OK to apply the changes.
Disabling A Snapshot Virtual Disk Or Consistency Group Snapshot Virtual Disk
Use the Disable option when you want to invalidate a snapshot copy or a consistency group snapshot virtual disk. If the
snapshot virtual disk or consistency group snapshot virtual disk is designated as read-write, this option also allows you
stop any further write activity to its associated snapshot repository virtual disk.
Use the Disable option if one of these conditions applies:
•
You are finished with the snapshot virtual disk or consistency group snapshot virtual disk for the time being.
•
You intend to re-create the snapshot virtual disk or consistency group snapshot virtual disk (that is designated
as read-write) at a later time and want to retain the associated snapshot repository virtual disk so that it does
not need to be created again.
•
You want to maximize the storage array performance by stopping write activity to the snapshot repository virtual
disk.
If you decide to re-create the snapshot virtual disk or consistency group snapshot virtual disk, you must choose a
snapshot image from the same base virtual disk.
If you disable the snapshot virtual disk or consistency group snapshot virtual disk, the system performs the following
actions:
•
Retains the World-Wide Name (WWN) for the snapshot virtual disk or consistency group snapshot virtual disk.
•
Retains the snapshot virtual disk or consistency group snapshot virtual disk's association with the same base
virtual disk.
•
Retains the snapshot virtual disk or consistency group snapshot virtual disk's associated repository (if the virtual
disk is designated as read-write).
•
Retains any host mapping and access (any read-write requests will fail).
•
Removes the snapshot virtual disk or consistency group snapshot virtual disk's association with the current
snapshot image.
•
For a consistency group snapshot virtual disk, disables each member's snapshot virtual disk.
NOTE: If you are finished with the snapshot virtual disk or consistency group snapshot virtual disk and do not
intend to re-create it at a later time, you must delete the virtual disk, instead of disabling it.
1.
From the AMW, select the Storage & Copy Services tab.
2.
Select the snapshot virtual disk or consistency group snapshot virtual disk that you want to disable and then select
one of the following:
–
Copy Services → Snapshot Virtual disk → Disable. The Confirm Disable Snapshot Virtual Disk window is
displayed.
