page 23.) When VTS detects a mount request, it checks to see if the requested virtual tape
resides on a RAID array connected to VTS. If it does, that virtual tape is mounted on the
device specified by the mount request. If no device is specified in the backup command, the
first available virtual tape drive connected to that host is used. After the virtual tape is
mounted, the backup proceeds automatically.
The Virtual Media - Mounts and Locks page enables you to monitor mount activity and to
view current locks on pools and virtual tapes.

To view mounts and locks
1. Click Virtual Media on the navigation pane.
2. Select mounts and locks from the window menu at the top of the Virtual Media -
Operation page.
The top of the page shows the recent mount requests. Only mount requests that can be
handled by the server are displayed. You can also restart the EMS messaging service from
this page by clicking the RESTART button.
The bottom of the page shows the current locks, which ensure that virtual tapes are only
accessed by one process at a time. Pools are locked when VTS needs uninterrupted access to
any of the cartridges in a pool. Under normal conditions, manual lock maintenance is not
necessary; these locks are created and deleted by the VTS processes. Removing a lock here
should only be done if a VTS process terminated abnormally.
