Virtual TapeServer 8.4 Configuration Guide

176 | Virtual TapeServer Configuration Guide
l From the NonStop server, enter STATUS *, USER (username) to see if the EMSDIST process is
active.
l Check /usr/local/tape/log/ems.log. Go to the bottom of the log to look for problems.
l View the Virtual Media - Mounts and Locks page. View the list of locked virtual tapes. If you
are certain that a particular virtual tape is not in use but VTS indicates that it is locked,
remove the lock here.
Virtual tape operations
If you are unable to manually mount a virtual tape, perform the following:
l Check the color of the virtual tape label. Gray indicates the virtual tape is in use by
Import/Export or is remotely mounted.
l Verify that the autoloading library containing the virtual tape is not in use.
l Verify that Data Encryption is enabled and configured properly in a cluster environment. The
mount will fail, for example, if the key server is not configured on all servers.
If virtual tapes are mounted as read-only or write failures occur, verify that licensing has not been
exceeded (for the VTD or Capacity license).
If you cannot import a physical tape, perform the following:
l Check the tape drive for power.
l Check the tape drive for tape ready indicators.
l Check the SCSI cable to the tape drive.
l Check file system Free (Pct).
If you cannot export a virtual tape or an export failed, perform the following:
l Check the tape drive for power.
l Check the tape drive for tape ready indicators.
l Check the SCSI cable to tape drive.
l Check that the tape is in the drive.
l Check the media write-protection.
If you cannot access a virtual tape because it is locked, perform the following:
l Check MEDIACOM for label in use.
l Check other VTS systems for remotely mounted virtual tapes.
l Reboot VTS to clear all local file locks.
If an autoloading pool did not recycle, verify that Autoloading or Recycle is selected on the Pool
Maintenance page. If virtual tape operations failed to a remote server, verify that licensing has not
been exceeded (for VTD or Capacity licenses).
