Cause:
• Shared memory for the V-VOL management area is not installed.
Solution:
• Call the HP Technical Support and check if the shared memory for
the V-VOL management area is installed.
Cannot install Thin Provisioning Z.
Causes:Pool usage level exceeds the threshold.
• Too many THP V-VOLs are associated with a pool, or too much data
is stored in a pool.
• 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
(page 62).
• Set a larger value to the threshold of the pool. See (page 59).
After correcting the causes of SIM 620XXX, or 620XXX and 626XXX,
you need to complete the SIMs (see (page 61)). If you do not complete
the SIMs, no new SIM will occur even if the usage level increases and
again exceeds the threshold (target SIM codes are 620XXX, and
626XXX).
SIMs 620XXX, 625000, and 626XXX are automatically completed if
you increase pool capacity by adding pool-VOLs because the condition
that caused the SIM is removed.
Caution: You need free volumes to add as pool-VOLs. If there are no
free volumes, create new volumes or ask the HP Technical Support to
add. Therefore, it may take time to solve the problem.
Causes:Cannot create a THP V-VOL.
• Usage of the pool has reached to 100%.
• Something in the storage system is blocked.
• Too many THP V-VOLs are assigned, or Subscription Limit is too low.
Solutions:
• Add some pool-VOLs to the pool. See (page 62).
• Increase the value of Subscription Limit for the pool. See (page 59).
• Ask the HP Technical Support to solve the problem.
