Hi Carl,
This sounds very much like you have problem with your (or one of yours)
ADAPTEC SCSI controller. But I guess you probably already spotted that.
That the media database can't be repaired probably indicates that the
SCSI transport is corrupted. Have you checked the controller(s)? Can
you access the devices? Have you checked the cables? The SCSI chain
length?
Regards,
David

Kernel panic working with Dell Power Edge 2800 and Dell
PV136T(adic100)library.
I have problems with my new backupserver. When I work with the library
I sometimes
get a dump Kernel panic:Fatal exception on the server. The
screen-dump talks about aic7xxx and some scsi-mod commands. At the
same time the networker media-database (mm) i corupted and it can't
be repaired.
Environment:
Server Dell Power Edge 2800 with 4 Gb memory and 4 2-channel adaptec
scsi-controllers.
The server is running Red Hat Enterprise Linux ES release 3 (Taroon
Update 3)
Kernel is 2.4.21-20.EL #1 SMP Wed Aug 18 20:34:58 EDT 2004 x86_64
x86_64 x86_64 GNU/Linux
The library is a Dell PV136T with 6 LTO-2 drives, each connected to
it's own scsi-port.
Some output from dmesg
<<<<<<<<<<<<<<<<< Dump Card State Ends >>>>>>>>>>>>>>>>>>
scsi0:0:0:0: Cmd aborted from QINFIFO
aic7xxx_abort returns 0x2002
st6: Failed to read 65536 byte block with 32768 byte read.

Could it be some of the setings on the jukebox that should be changed?
Have anyone seen something familiar.
Any help would be appreciated.
