All of a sudden drive choice errors DP 8.1

We have our backups set to use any of 14 virtual drives.  Always have.  So when a copy uses some of the drives and tape drives (for example VLS drives 10 and 11 and LTO drives 3 and 4), a backup that is set to use any drive 1-14 can pick ANY number that is open.  TODAY the software is giving the false alarm:

[Critical] From: BMA@sapbck.ssmhc.com "HP:Ultrium 3-SCSI_10_sapbck" Time: 2/8/2016 5:56:09 PM
[90:63] => UMA@sapbck.ssmhc.com@/dev/rchgr/autoch1
Cannot load exchanger medium (Target drive is busy.)

Duh! it is being used and the backup can choose from 12 other drives!  And it does BUT I get the error now.  How do I stop DP 8.1 from a false alarm on EVERY backup!  About the ONLY change that was made was the server the CM is on got bounced.

Running DP 8.1 on HP-UX 11.31

  • not sure if I got it but you may use scsi reserve release option in your changer.

    In order for the backups to work right I ended up performing the following steps:

    • Stopping the Daily Copy
    • Stopping Data Protector (omnisv.sh stop)
    • Clearing things out of /var/opt/omni/tmp
    • Moving tapes from drives back to slots via uma
    • Starting Data protector (omnisv.sh start)
    • Clearing any old session (omnidbutil -clear)

    Now the current Daily Copy AND backups are all happy again.

    Thanks for all the suggestions!

  • do you use multiple Device-Specs for the same phyiscal Device? If so make sure to use the same Lock-Name on all of those. Also check whether a previous session had an error and left the tapedrive locked and loaded, causing the fault of the copy.
