NOTE:
If needed, these disks can be unpresented. See Deleting Array LUNs. If you unpresent
a LUN, you must then reconfigure the LUN numbering for all LUNs on the VLS Gateway
that follow the unpresented LUN in sequential numbering.
Managing VLS12000 Gateway Capacity
There are several ways to manage the capacity of your Gateway system:
• Add external LUNs to the VLS Gateway configuration. See Discovering Array LUNs.
• Delete external LUNs from the VLS Gateway configuration. See Deleting Array LUNs.
• Create storage pools. See Configuring Storage Pools.
• Destroy storage pools. See Deleting Array LUNs
• Enable device-side data compression when creating new tape drives. See “Creating Tape
Drives” on page 132
Discovering Array LUNs
1. Discover the LUNs, either by rebooting the entire VLS Gateway or:
a. Open a Command View VLS session and log in as the administrator. See “Opening a
Command View VLS Session from a Web Browser” on page 105.
b. In the Storage tab navigation tree, select Storage LUNs.
c. Select Discover Unconfigured Storage from the task bar. This causes the VLS to recognize
all presented LUNs and return the following message: # storage lun(s) discovered.
# storage lun(s) deleted. At this point, the LUNs are still unconfigured.
