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.
