General troubleshooting
The following table shows FS troubleshooting information.
Causes and solutions Problem
Cause: The pool is blocked. Pool information is not shown.
Solution: Recover the blocked pool. For more information, see “The workflow for recovering
blocked pools workflow” (page 66) .
Cause: A pool is blocked.
• The pool-VOLs are blocked.
•
The pool reaches full capacity.
Solution:
1. Recover the blocked pool.
For more information about recovering blocked pools, see “The workflow for recovering
blocked pools workflow” (page 66) .
2. Complete the SIMs.
For more information about completing SIMs, see “The workflow for processing pool-related
SIMs” (page 66) .
Causes: Pool usage rate exceeds the
threshold.
• You have too much snapshot data stored in the pool.
•
The pool’s capacity is insufficient.
•
The pool threshold is too low.
Solutions:
1. Complete one or more of the following:
• Decrease the pool’s usage rate. To do this, delete all of the snapshot data in the P-VOL.
• Increase the pool’s capacity. To do this, add more pool volumes.
• Increase the pool’s threshold. To do this, set a larger value for the pool threshold.
2. Complete the SIMs.
For more information about completing SIMs, see “The workflow for processing pool-related
SIMs” (page 66) .
3. Ensure that you have enough unused volumes to add the pool volumes. If you do not have
unused volume, create new volumes or contact HP Technical Support to have a representative
add the hard disks.
Note: This problem can take time to solve.
Causes: Cannot add pool-VOLs.
•
The maximum 1,024 pool-VOLs are already set in the pool.
• Available pool management block in the V-VOL management area in the shared memory is
insufficient.
•
Pool-VOL requirements were not followed.
Solutions:
•
Add pool-VOLs to another pool.
• Initialize the V-VOL management area.
•
Check pool-VOLs requirements.
