Hi: I'm having a problem with my new (well new to me) SCSI tape. My tape drive is as follows: (from dmesg:) (bt0:5:0): "WANGTEK 5150ES SCSI ES41 B170" type 1 removable SCSI 1 st0(bt0:5:0): Sequential-Access density code 0x5, 512-byte blocks, write-enable or if empty: (bt0:5:0): "WANGTEK 5150ES SCSI ES41 B170" type 1 removable SCSI 1 st0(bt0:5:0): Sequential-Access density code 0x10, drive empty and when I try to write to the drive I observe: # mt status Present Mode: Density = X3.136-1986 Blocksize = 512 bytes ---------available modes--------- Mode 0: Density = 0x00 Blocksize variable Mode 1: Density = X3.136-1986 Blocksize = 512 bytes Mode 2: Density = X3.39-1986 Blocksize variable Mode 3: Density = X3.54-1986 Blocksize variable # dd if=/kernel of=/dev/rst0 dd: /dev/rst0: Invalid argument 1+0 records in 0+0 records out 0 bytes transferred in 0.016702 secs (0 bytes/sec) # tar cvf /dev/rst0 /usr/sbin tar: Removing leading / from absolute path names in the archive. usr/sbin/ usr/sbin/uuchk tar: can't write to /dev/rst0 : Invalid argument # and this is generated on the console: st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0 st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0 st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0 st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0 st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0 st0(bt0:5:0): ILLEGAL REQUEST csi:0,8,0,0 But mt erase seems to work. At least the tape runs for quite awhile. My question: why is this happening? Could it be a media problem? The tapes were previously used with a lower density Wangtek (and Archive) drive on a Sun 3/60. I have tried using mt density to reset the density to different values, but this makes no difference. Any assistance appreciated. I've already searched the FAQ, Handbook, and mailing list archives.
