Hi
Maybe You can help me out with this one...
I have hp DLT connected to an adaptec SCSI board.
This is a part of dmesg output:
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.6
<Adaptec (Compaq OEM) 3960D Ultra160 SCSI adapter>
aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs
scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.6
<Adaptec (Compaq OEM) 3960D Ultra160 SCSI adapter>
aic7899: Ultra160 Wide Channel B, SCSI Id=7, 32/253 SCBs
Vendor: BNCHMARK Model: DLT1 Rev: 5032
Type: Sequential-Access ANSI SCSI revision: 02
The "BNCHMARK DLT1" is actually a hp DLT.
When rewinding this tape, using "mt -f /dev/nst0 rewind" with a reasonable
amount of data on the tape (~2 Gigs), i get the following in
/var/log/messages:

This does not happen with small amount of data on the tape, only when
rewind takes a *long* time
