After a power outage the tape that was currently in the drive can not
be used anymore. If bacula tries to append data the drive seems stuck
in "seeking" mode. After a while the kernel (Solaris 10) gives the
following error message:
Jun 8 10:27:52 yangtse scsi: [ID 107833 kern.notice] Requested Block: 0
Error Block: 0
Jun 8 10:27:52 yangtse scsi: [ID 107833 kern.notice] Vendor: HP
Serial Number:
Jun 8 10:27:52 yangtse scsi: [ID 107833 kern.notice] Sense Key: Media Error
Jun 8 10:27:52 yangtse scsi: [ID 107833 kern.notice] ASC: 0x14 (recorded
entity not found), ASCQ: 0x0, FRU: 0x0
If I use the "eod" command in btape I get an MTEOM I/O error.
btape scanblocks is able to read the tape up to file ??? (is still running).
If I insert a clean tape and run btape "test" everything is o.k.
In case it's just a missing mark on the stream how could I recover from
this error and save (at least most of) the data (~250GB) on the tape?
Hardware:
HP Ultrium-2 drive, LTO-2 Tape
Any hints appreciated.
