problems with backup-tape under openBSD 3.6
Hi I am using a backup tape witch at the moment runs under suselinux 7.3. Now I am migrating to openbsd and try to read my data witch are written under linux from a tape that runs under openbsd 3.6. The problem is: there is only a small part of what I backuped, and during the read-process tar says: missing header for file XX -search for header I used the tape before under freeBSD 4.11 (driver: sa0) and never encountered that problem. I suspect that st only rekognises dds3 tapes. If so, what can I do? The tape hardware is hp surestore dat dds4 Configuration under openbsd: |-siop0 | \-scsibus1 | \-st0 (dmassage -t) mt status says: mt -f /dev/st0 status SCSI tape drive, residual=0 ds=3Mounted er=0 blocksize: 0 (0, 0, 0, 0) density: 38 (0, 0, 0, 0) thanks in advance, Erwin -- Lust, ein paar Euro nebenbei zu verdienen?

Dunno about st(4) and dds3 tapes, but I can think of two things to try: - Errata 001 for 3.6 fixes a scsi tape problem. - The archive was written using gnu tar. Try reading it back with gnu tar. If this succeeds, I'd really like to know what's in the archive, to see what is going wrong. -Otto
