Hello
I have had this problem before and found a script that monitors the drives
and tries to bring them up again if they are down. The nice part is, it will
email you if the drive status changes.
I have added this into my crontab to look every 15 min's:
-----------------------------------------------------------
# Execute Tape Library Monitor Script every 15 minutes
15,30,45,00 * * * * /Admin/drivewatch.sh >/dev/null 2>&1
-----------------------------------------------------------
Here's the script: - drivewatch
-------------------------------------------------------------------------
#!/bin/sh
#
#********************************************************************
#Copyright 1998, DataStaff, Inc.
#
# Filename: drivewatch
#
# Purpose: This script uses the results of vmoprcmd -d ds
#          to determine if a drive is in a DOWN state.
#          If the drive appears to be down, it will attempt to
#          set it to an up state and email the someone_who_cares
#          variable to notify them of the potential problem.
#          Should any of the drives be down, this script will report
#          that to a log /tmp/drivecheck.SERVERNAME and attempt to
#          place the DOWN'd drives to an UP state.
#
# Caveat:  The command vmoprcmd will only apply to media servers.
#          Therefore, if this is running on a master only, you
#          will need to use the -h option to designate which media
#          server to query.
#
#          This script also assumes all servers are also media servers.

# Revision History:
# 01/26/98      Initial Creation
#               - David Chapa
# 02/25/99      Updated design and added more functionality
#               -David Chapa
# 10/14/00      Added functions to support more than one server
#               -David Chapa
#
# 6/28/01       Now we get all VALID server names by using
#               bpstulist and sorting unique.  Prior to this
#               we would may have gotten administrative clients
#               (pc's).
#               -David
#
# 02/26/02      Variable-ized the robot type. RTYPE should be
#               modified depending on the type of tape library
#               you have.  ie. TLD, ACS, TL8, TL4, etc.
