DDS 4 - problem with writing set marks

[zblazer]

HP Proliant ML350 G3, OpenServer 5.0.5, HP StorageWorks DAT 40 - can't write set marks to the tape correctly. I can write files to tape fine using cpio. When I issue the command 'tape wsm' nothing is reported back as an error. When I issue the ' tape rsm' command, I get the following error:

"tape:unable to 'rsm' command on '/dev/xct0' :I/O error"

If I put in a tape written on a DDS 3 drive, it will read the set marks just fine.

Where is the problem? Tape drive firmware? SCO stp driver?

Anyone?

does it give you the same error if you rewind the tape in between the wsm and rsm commands?

this is dds2 or larger media?
