Backups won't start and server_log contains NDMP_DEVICE_BUSY_ERR errors

Hi,

We're having an issue where backupexec tries to start backup jobs, but for some reason they stay queued forever.

Checking server_log, we saw that we have errors on the library:

Error opening SCSI device: c80t0l2 NDMP_DEVICE_BUSY_ERR

here's the output of server_devconfig:

jbox2               c80t0l2      jbox  DELL PV-132T 310D310D GY004

It looks like restarting the server/tape library will get the job to start, but won't necessarily complete successfully.  Everything worked fine up to now, nothing changed in the setup.

We use a NS480 with code 5.6.44-4

Anyone has a guess on what we should check?

thanks

    How is the robot control configured in BU?  Are running BU 12.5 with Shared Storage?  Does the backup fail at a media swap or some other point?  Does BU have anything useful in the log (maybe a control timeout or some such)?

    Thanks!

    Hi,

    are you using DDS ( Dynamic Drive Sharing ) ? If yes, set the param NDMP scsiReserve to "0". ( check with command server_param server_2 -f NDMP -i scsiReserve -v ). This might cause the device_busy errors.

    Other possible cause is the drive index does not match the Celerra order. If this is the case, run a rescan ( server_devconfig server_2 -c -s -n ), and try again.

    I hope it helps you.

    Gustavo Barreto.

    After the rescan make sure the backup software device configuration vs. Celerra tape device configuration matches before retesting.
