Workflow for registering virtual volumes
Use the following workflow to register virtual volumes:
1. (Optional) Edit the SSID of the V-VOL you want to register to the pool-VOL’s paired volume
(see
“Editing the SSID for virtual volumes” (page 42) ).
2. (Optional) Change the V-VOL settings (see “Changing LDEV settings” (page 44) ).
3. Register the V-VOL (see “Creating LDEVs” (page 51) ).
Editing the SSID for virtual volumes
Before registering a V-VOL, you may need to edit the control unit’s (CU) SSID, which you use to
create new LDEVs. Use the Change SSIDs window to edit a V-VOL’s SSID.
Prerequisite: The SSID must be newly allocated (SSID Changeable status is Yes.)
For more information about registering V-VOLs, see “Creating LDEVs” (page 51) .
1. In the RWC main window, in the resource tree in the Explorer, click Pools.
2. In the Pools window, in the Pools tab, click Create LDEVs.
