Problems Causes and Solutions
Pool usage rate exceeds
the threshold.
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 which is less important or delete the
old snapshot data to decrease the usage rate of the pool. See
“ Deleting XP Snapshot Pairs ” on page 65.
• Add some pool volumes to increase the capacity of the pool. See
“ Creating New Pools ” on page 54.
• Set a lager value to the threshold of the pool. See
“ Changing the Information of the Pools ” on page 55.
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 ” on page 76.
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.
Cannot add pool-VOLs.
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. See “ Creating New Pools ” on page 54.
• Initialize the V-VOL management area. See
“ Initializing V-VOL Management Area ” on page 57.
• Add the pool-VOLs that fulfill the requirements. See
“ Volume Requirements ” on page 25.
Cannot create XP
Snapshot pairs.
Causes:
• There are not enough differential tables to create the pairs.
• The conditions to create the pair are not fulfilled.
• The volumes specified to create the pair is in SMPL(PD) status because
the pair is being deleted.
Solutions:
• Secure enough differential tables to create the XP Snapshot pairs. See
“ Calculating Maximum Number of Pairs ” on page 27.
• Fulfill the conditions to create the pair and try the pair creation again. See
“ Creating XP Snapshot Pairs ” on page 64.
• See Business Copy’s Pair Operation window and verify that the status of
the volume changes to SMPL, and then try the pair creation again.
• Execute RAID Manager’s inqraid command and verify that the volume is
not used by XP Snapshot, and then try the pair creation again.
XP Snapshot pairs are not
displayed in the volume
list.
Causes:
• XP Snapshot pairs are not created.
• Displaying of the XP Snapshot pairs is prohibited by the filtering function.
Solutions:
• Create XP Snapshot pairs. See “ Creating XP Snapshot Pairs ” on page 64.
• Change the settings in the Display Filter dialog box. See
“ Configuring the Volume List ” on page 52.
