Restarting Vls Device Emulations; Updating The Firmware - HP StorageWorks 6000 - Virtual Library System User Manual

Restarting VLS Device Emulations

Restart VLS device emulations:
• If the VLS locks up
• After destroying a virtual device (library or tape drive) on the VLS and doing so leaves a gap in
the virtual device LUN numbering on an Fibre Channel host port
• After adding a virtual tape drive and the default LUN number assigned to it is not consecutive with
the other virtual tape drives in the same library
CAUTION:
Restarting VLS device emulations changes the default virtual device LUN numbers if there is a gap in
the LUN numbering, or if there is a tape drive whose LUN number is not consecutive with the other
tape drives in the same library. The firmware changes the LUN numbers as necessary to remove the
gap or to make the virtual tape drive LUN numbers consecutive in each library, so that the virtual
device LUN numbering meets the operating system LUN requirements. When this occurs, on each
host:
• Rescan the SAN with the operating system for hardware changes.
• Rescan for new devices with the backup application and update the backup application device
files.
CAUTION:
Restarting VLS device emulations places the VLS cartridges back into the same library slots and tape
drives they were in at the time of reboot/restart. To move the cartridges from tape drives back into
the appropriate slots, use Force Unload from the task bar visible when you select the tape drive from
the navigation tree.
To restart the VLS device emulations:
1. Open a Command View VLS session and log in as the administrator. See
"Opening a Command View VLS Session from a Web
2. Click Chassis in the navigation tree.
3. Click on System Maintenance under Maintenance Tasks.
4. Click Restart Emulations in the task bar.
The Restart Emulations window opens.
5. Click Restart Emulations to confirm.
