The Operation Succeeded message displays on the status pane. Click OK. h. Repeat these steps for each disk to present to the VLS. NOTE: If needed, these disks can be unpresented. See To unpresent a LUN. If you unpresent a 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 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 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 LUNs are properly assigned and that there are two data paths for each LUN. 40 Storage configuration

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

.
c.
Select
Discover Uncon
fi
gured 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 uncon
fi
gured.
2.
Verify that the LUNs are properly assigned and that there are two data paths for each LUN.
