Subject: Can someone explain "Data Phase Error"
Date: Fri, 17 Dec 2004 16:23:24 -0500 [thread overview]
Message-ID: <87f94c3704121713233f8499d8@mail.gmail.com> (raw)
All,
Environment:
kernel - 2.6.8-24 (from SUSE 9.2)
tape drive - IBM LTO-1 (scsi-wide)
scsi controller - Adaptec 2940
Issue:
I am trying to build a pair of new Linux based tape servers.
I have written exactly one tape on each, I then swapped the tapes
beween the units and tried to do a restore. One seems to be working
fine on this first test, but with the other I get:
Dec 17 08:52:04 linux kernel: st0: Error with sense data: Info
fld=0x40000, ILI Current st0: sense = f0 2b
Dec 17 08:52:04 linux kernel: Additional sense: Data phase error
I would suspect a bad tape, but a simple "dd if=/dev/st0 of=/dev/null
bs=256k" fails at a different number of blocks each time.
i.e. I have 130 GB of data on the tape, but I have not yet read back
more than 6 GB of it. The data itself is unimportant, I'm just
testing the process.
I am continueing to test and am now trying another tape, but I want to
understand this initial failure if I can.
Thanks for any help.
Greg
