LUN, you must then reconfigure the LUN numbering for all LUNs on the VLS300 that
follow the unpresented LUN in sequential numbering.
Managing VLS300 capacity
There are several ways to manage the capacity of your system:
• Add external LUNs to the VLS300 configuration. See Discovering array LUNs.
• Delete external LUNs from the VLS300 config uration. 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
Discovering array LUNs
1. Discover the LUNs, either by rebooting the entire VLS300 or:
a. Open a Command View VLS session and log in as the administrator. See Opening a Command
View VLS session from Command View TL.
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.
2. Verify that the LUN s are properly assigned and that there are two data paths for each LUN.
