Hi Bob $ all,

I have the same error on 4 of my 9 autochanger Storage Tek 9710 since we
moved (march/april) from Legato 6.2 to Legato 7.1.1. and is a symptom for
a bigger problem.

The presumed cause of my error is that Legato - every time a major
incident happens (like a power outage) - has problems due to the loss of
the HW configuration. Sometimes the autochanger is not to be reached,
sometimes devices simply disappear . I experienced that after a reboot or
an HW scan of my HW sometimes plus a reconfiguration (with jbconfig) of
the HW the backups runs again.

The new backup servers are DL380 with SCSI controller provided by our
customer . Operative System is W2003 .

What I mean is : Legato cannot read the HW anymore (tapes and inquire -l
commends show a mismatch between SCSI connections and sequence of the
connections of the devices), tries to unload/load tapes but of course
failes, the tapes in the devices cannot be read anymore. Most of the time
the devices are physically empty, nevertheless tapes are shown.

Here what happened in one location and we did not touch anything:

We are investigating the HW at the moment

eventid=9&eventno=2410&source=symc8xx&phase=1

It would be a help knowing if somebody is having the same problems.

Best regards!
