XP Thin Provisioning Troubleshooting
Table 15 (page 74) provides troubleshooting instructions for XP Thin Provisioning operations.
Table 15 Troubleshooting for XP Thin Provisioning
Causes and Solutions Problems
Cause:
• Shared memory for the V-VOL management area is not
installed.
Solution:
•
Call HP technical support and check if the shared memory
for the V-VOL management area is installed.
Cannot install XP Thin Provisioning.
Causes: Pool usage level exceeds the threshold.
• Capacity of the pool is insufficient.
•
The threshold of the pool is too low.
Solutions:
•
Add some pool-VOLs to increase the capacity of the pool.
See
“Viewing Pool Information” (page 53) . Also, consult HP
for best practices on adding capacity.
• Set a larger value to the threshold of the pool. See “Changing
the Pool Threshold” (page 55) .
After the causes of SIMs 620XXX and 621XXX are resolved, you
will need to complete the SIMs. If you do not complete the SIMs,
no new SIMs will occur ( even if the usage level increases and
again exceeds the threshold).
SIMs 620XXX, 621XXX, and 625000 are automatically
completed if you increase pool capacity by adding pool-VOLs
because the condition that caused the SIM is removed.
For details about how to complete SIMs, see “Managing
Pool-Related SIMs” (page 78) .
You need free volumes to add as pool-VOLs. If there are no free
volumes, you need to create new volumes or ask HP technical
support to add hard disks. Therefore, it may take time to solve
the problem.
Causes: Cannot add pool-VOLs.
• 1024 pool-VOLs are already defined in the pool.
•
The CLPR number of pool-VOL that you added is different
from the CLPR number of the existing pool-VOL. In one pool,
all pool-VOLs must be assigned to the same CLPR.
•
There is no available free LDEV to add to the pool.
• Something in the storage system is blocked.
