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'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.
