Unfortunately I just have the one drive in on index 0. I have frozen =
some tapes and started backups again.
There are things in /var/adm/messages such as  'error blocks' , 'sense =
key media error'
Then it downs the drive.

Tis all odd. Its a SEAGATE ULTRIUM LTO type drive and im wondering if =
theres any firmware patches required or anythign i dunno. Just not sure =
how to find out firmware versions. Mind you why would the other clients =
work :(

Thanks
Dave

  Check your /var/adm/messages for that particular drive (index 0), see =
if there are messages being logged there.

  =20

  I would also run a bpimmedia -d mm/dd/yyyy -e mm/dd/yyyy -U

  =20

  To see what the DWO column says for the backups that have been =
successful. It sounds like it is a device problem if none of those =
backups were written to Device Index 0.  If they have, then I would (if =
you can during the day), down all drives except Index 0 and run a few =
backup jobs to the drive.  Incidentally, keep in mind that this may in =
fact be a media issue as well.  I hope this helps.

  Has any one seen this scenario before.

  =20

  I run netbackup 4.5 MP6 on Solaris 8 using a L25 tape unit attached =
with an LTO tape drive and LTO tapes.

  =20

  Ok

  =20

  Currently i have 4 Solaris 8 UNIX clients 1 Linux client and 2 windows =
clients.

  =20

  Now,=20

  =20

  the UNIX clients backup ok, but when the backup server backs itself up =
as client it always fails with media write error. 84.

  Also the Linux client fails with media write error 84 and the windows =
clients sometimes work and sometimes give 84.

  Strange thing is the other UNIX clients seem to give status 0.

  =20

  Looking in bptm logs I see errors of "drive on index 0, I/O error"

  =20

  This seems to happen and then abort backup with media error 84.

  I tried using a different tape and same thing.

  =20

  Sometimes it gives storage unit 219 not available and i saw that NBU =
downed the drive after 3 errors.

  =20

  Any help at all?

  =20

  Dave
