Snapshot Repository Virtual Disk Capacity - Threshold Exceeded

What Caused the Problem?

The snapshot's repository virtual disk capacity has exceeded a warning threshold level. If the repository virtual disk's capacity becomes full, its associated snapshot virtual disk can fail. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

 Caution: Risk of Snapshot Virtual Disk Failure. This failure should be resolved immediately to ensure you maintain a usable snapshot virtual disk.

Important Notes

Recovery steps

1 It will help to estimate how quickly the snapshot's repository capacity is being used when determining whether you should increase the capacity of the repository virtual disk or increase the repository threshold capacity warning level. The following procedures will help you estimate how quickly the repository capacity is being used.

Procedure #1
a Highlight the repository virtual disk. Then, select Virtual Disk >> Properties and select the Capacity tab. Record the repository's current used capacity.
b With the repository virtual disk still highlighted, select View >> Go To >> Snapshot Virtual Disk. Then, select Virtual Disk >> Properties. Record the snapshot virtual disk's creation timestamp.
c Use the current date to calculate the time it has taken to reach the current repository capacity level.

Procedure #2
a Highlight the repository virtual disk. Then, select Virtual Disk >> Properties and select the Capacity tab. Record the current time and the repository's current used capacity.
b Wait 10 minutes and repeat step a.
c Use the above information to calculate the current rate of repository capacity usage. Note that if the capacity has not changed you may need to increase the wait time in step b.

Use one or both of the procedures to determine if the snapshot's repository capacity will be close to 100 percent during the snapshot's expected lifetime. If it will, you should increase the repository's capacity. If not, you may want to consider increasing the repository threshold capacity warning level.

If... Then...

The snapshot virtual disk associated with this snapshot repository virtual disk is also a source virtual disk in a copy operation and its copy status is Pending or In Progress

Go to the Copy Manager by selecting Virtual Disk >> Copy >> Copy Manager. If you want to keep the data being copied, allow the copy operation to complete before going to step 3.

If you do not want to keep the data being copied, highlight the copy pair that contains the snapshot virtual disk and select Copy >> Stop.
The snapshot virtual disk associated with this snapshot repository virtual disk is also a source virtual disk in a copy operation and its copy status is Failed Highlight the copy pair that contains the snapshot virtual disk and select Copy >> Stop.

If... Then...
You wish to increase the repository virtual disk's capacity
a Highlight the repository virtual disk in the Logical View of the Array Management Window. Then, select Virtual Disk >> Increase Capacity.
b Select the amount of capacity you wish to add to the repository virtual disk. Note that if you have unassigned physical disks available, you can specify an additional physical disk to use as available capacity.
c Select the OK button and confirm your selection by typing in yes in the confirmation dialog.
d Wait for the virtual disk capacity expansion to complete. Select Virtual Disk >> Properties to monitor the capacity expansion's progress.
e Go to step 4.

You wish to increase the repository virtual disk's capacity threshold warning level
a Highlight the repository virtual disk in the Logical View of the Array Management Window. Then, select Virtual Disk >> Properties . Select the Capacity tab and adjust the threshold percentage to a value that is greater than the value currently displayed.
b Go to step 4.
4 Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.
