FlashCopy Repository Logical Drive Capacity - Threshold Exceeded

What Caused the Problem?

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

 Caution: Risk of FlashCopy Logical Drive Failure. This failure should be resolved immediately to ensure you maintain a usable flashcopy logical drive.

Important Notes

Recovery steps

1 It will help to estimate how quickly the flashcopy's repository capacity is being used when determining whether you should increase the capacity of the repository logical drive 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 logical drive. Then, select Logical Drive >> Properties and select the Capacity tab. Record the repository's current used capacity.
b With the repository logical drive still highlighted, select View >> Go To >> FlashCopy Logical Drive. Then, select Logical Drive >> Properties. Record the flashcopy logical drive'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 logical drive. Then, select Logical Drive >> 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 flashcopy's repository capacity will be close to 100 percent during the flashcopy'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 flashcopy logical drive associated with this flashcopy repository logical drive is also a source logical drive in a copy operation and its copy status is Pending or In Progress

Go to the Copy Manager by selecting Logical Drive >> 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 flashcopy logical drive and select Copy >> Stop.

The flashcopy logical drive associated with this flashcopy repository logical drive is also a source logical drive in a copy operation and its copy status is Failed Highlight the copy pair that contains the flashcopy logical drive and select Copy >> Stop.

If... Then...
You wish to increase the repository logical drive's capacity
a Highlight the repository logical drive in the Logical View of the Subsystem Management Window. Then, select Logical Drive >> Increase Capacity.
b Select the amount of capacity you wish to add to the repository logical drive. Note that if you have unassigned drives available, you can specify an additional drive 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 logical drive capacity expansion to complete. Select Logical Drive >> Properties to monitor the capacity expansion's progress.
e Go to step 4.

You wish to increase the repository logical drive's capacity threshold warning level

a Highlight the repository logical drive in the Logical View of the Subsystem Management Window. Then, select Logical Drive >> 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.
