HP 9000 Virtual Library System - Manual (Page 44)

1. Install the capacity licenses. See “Installing Additional Licenses” (page 46) .
Each base and capacity enclosure comes with its own capacity licenses (10 TB enclosures
require one license while 20 TB enclosures require two).
CAUTION: If a base or capacity enclosure is added to a VLS system without sufficient capacity
licenses installed, a capacity license violation will occur.
If the capacity license violation is detected during boot, this will disable the VLS storage
capacity, so that the VLS is unable to perform for read/write operations. VLS storage capacity
is re-enabled once the capacity license is installed on the VLS (without needing to reboot).
If the capacity license violation is detected when Discover Unconfigured Storage is selected,
this will prevent the new disk array enclosure from being added to the VLS. However, the VLS
will remain operational. When the capacity license is then installed, the new disk array
enclosure is automatically added to the VLS (without needing to reboot).
2. Install the base or capacity enclosure into the rack. See “Installing the Disk Array Enclosures
into a Rack” (page 22) .
3. Cable the enclosure to the VLS. See “Cabling Disk Array Enclosures” (page 26) .
4. Power on the enclosure. See Powering on VLS Arrays (page 89) .
5. Add the new disk array storage to the VLS using Command View VLS:
a.
Select the System tab.
b. In the navigation tree, select Storage LUNs.
c. Select Discover Unconfigured Storage from the task bar.
The VLS locates the new array or capacity enclosure and the screen displays the LUN
capacity that will be added to the storage pools, based on the storage pool policy, as a
result of the new enclosure.
NOTE: If the screen displays “0 storage LUN(s) discovered,” check the notifications.
You may have a problem that prevented the array from being configured or a license
violation that prevented the array from being added.
d. Click Run Pool Policy. The VLS adds the new LUNs to the storage pools.
If you opt to cancel instead, you can return later and add the new storage to the storage
pools using the Run Pool Policy task (see
“Adding New Arrays to the Storage
Pool” (page 46) ).
e. Click Return to return to the Storage LUNs screen.
Removing VLS Capacity
Remove capacity by decreasing the number of VLS disk array enclosures installed in your VLS
system. At a minimum, one disk array enclosure must be installed for every node.
Removing disk array enclosures from the system destroys all current virtual tapes in the system.
Once disk array enclosures are added to the VLS, the only way they can be removed from the a
VLS storage pool is using the following procedure:
1.
Power off the nodes.
2. Remove the disk array enclosures.
3. Power on the nodes.
4. Run the Rebuild All Storage Pools operation (see Rebuilding all Storage Pools ).
This deletes the disk array enclosures from the configuration and reformats the remaining disk array
enclosures into working capacity.
