Hi All, Can anyone explain the following problem. 1. rewind tape, dump, rewind tape 2. forward to end of 1st dump, dump, rewind tape 3. Attempt to repeat step 2. This causes the following error message. (sa0:ncr0:0:6:0): WRITE(06). CDB: a 0 0 80 0 0 (sa0:ncr0:0:6:0): ILLEGAL REQUEST asc:90,1 (sa0:ncr0:0:6:0): Vendor Specific ASC Here's a camcontrol inquiry on the device. This is an AIWA TR-5 tape. pass6: <AIWA TD-20001 0159> Removable Sequential Access SCSI-2 device pass6: Serial Number 8CB203D1 pass6: 10.000MB/s transfers (10.000MHz, offset 7) I've included the steps that caused this below. This is under 4.0 stable. --- Paul Haddad (paul@pth.com) AIM:(ETS Paul) Philadelphia is not dull -- it just seems so because it is next to exciting Camden, New Jersey. netserver/root# mt rewind netserver/root# /sbin/dump -0 -ua -b 32 -f /dev/nrsa0 /dev/da0a DUMP: Date of this level 0 dump: Tue Apr 25 17:41:24 2000 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/da0a to /dev/nrsa0 DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 27226 tape blocks.
