Table 32 Troubleshooting for XP Snapshot
Causes and Solutions
Problem
Causes:
•
Shared memory for the V-VOL management area is not installed.
•
Shared memory is not set for the V-VOL management area.
•
Shared memory for the differential tables is not installed.
Solutions:
•
Call HP technical support and check if the shared memory for the V-VOL
management area and the differential tables is installed.
•
Call HP technical support and check if the shared memory for the V-VOL
management area is set correctly.
Cannot install XP
Snapshot.
Causes:
•
The pool is blocked.
Solutions:
•
Implement the measures described in
“Procedure to Recover a Blocked Pool”
.
Pool information is not
displayed.
Causes:
•
The pool-VOLs are blocked.
Solutions:
•
Implement the measures described in
“Procedure to Recover a Blocked Pool”
. In addition, after the problems are solved, you need to complete
the SIMs. If you do not complete the SIMs, no new SIM can occur even if a
pool is blocked again. For details about the procedure to complete SIMs,
see
“Procedure to Complete the Pool-Related SIMs” (page 102)
A pool is blocked.
Causes:
•
Too much snapshot data is stored in the pool.
•
Capacity of the pool is insufficient.
•
Threshold of the pool is too low.
Solutions:
•
Delete the snapshot data that is less important or delete the old snapshot
data to decrease the usage rate of the pool.
•
Add some pool volumes to increase the capacity of the pool.
•
Set a larger value to the threshold of the pool.
In addition, after the problems are solved, you need to complete the SIMs. If
you do not complete the SIMs, no new SIM can occur even if the usage rate
exceeds the threshold again. For details about the procedure to complete SIMs,
see
“Procedure to Complete the Pool-Related SIMs” (page 102)
.
NOTE:
You need unused volumes to add the pool volumes. If there is no
unused volume, you need to create new volumes or ask HP technical support
to add the hard disks. Therefore, it may take time to solve the problem.
Pool usage rate exceeds
the threshold.
Causes:
•
1,024 pool-VOLs are already set in the pool.
•
The available pool management block in the V-VOL management area
(which is in the shared memory) is insufficient.
•
The requirements of the pool-VOLs are not fulfilled.
Solutions:
•
Add pool-VOLs to another pool.
•
Initialize the V-VOL management area.
•
Add the pool-VOLs that fulfill the requirements.
Cannot add pool-VOLs.
