3. Click “
“. There will pop up a confirmation page.
4. Choose “OK”
5. Done. The VG is deleted.
Tips : The action of deleting one VG will succeed only when all of the related UDV(s) are deleted in this VG.
Otherwise, it will encounter an error when deleting the VG.
Step 9:
Free global spare disk.
To free global spare disks, please follow the procedures.
1. Select
“/ Volume config / Physical disk”
.
2. Select the global spare disk by clicking the checkbox in the row, then click “
“ to free
disk.
Step 10:
Done, all volumes have been deleted.
• Example 2
Example 2 is to create two UDVs in one VG. One UDV shares global cache volume, the other uses
dedicated cache volume. First, dedicated cache volume should be created; it can be used in creating
UDV. Eventually, delete them.
Each UDV is associated with one specific CV (cache volume) to execute the data transaction. Each CV
could have different cache memory size. If there is no special request in UDVs, it uses global cache
volume. Or user can create a dedicated cache for indivifual UDV manually. Using dedicated cache
volume, the performance would not be affected by other UDV’s data access.
The total cache size depends on the RAM size and then set all cache size as global cache
automatically. To create a dedicated cache volume, first step is to cut down global cache size for the
dedicated cache volume. Please follow the procedures.
Step 1:
Create dedicated cache volume.
