OK, I admit that this may be user error, and if not it's probably not an
item for this list, but here goes:
Synopsis:
4.2-RELEASE on i386
Symbios 53c875 HBA
IBM 3490E/F01 deskside changer
read from tape is fine, write to tape fails with I/O error from sa0. This
happens regardless of the tape density, tape "newness", etc. Have
verified that the drive does work on SPARCstation 10 running Solaris.
Here's relevant bits from /var/log/messages:
sym0: <875> port 0xdc00-0xdcff mem
0xfaffe000-0xfaffefff,0xfafffc00-0xfafffcff irq 9 at device 11.0 on pci2
sym0: Symbios NVRAM, ID 7, Fast-20, HVD, parity checking
sym0: open drain IRQ line driver, using on-chip SRAM
sym0: using LOAD/STORE-based firmware.
sym1: <875> port 0xd800-0xd8ff mem
0xfaffd000-0xfaffdfff,0xfafff800-0xfafff8ff irq 10 at device 11.1 on pci2

it would appear that this is a problem related to dd -
$ dd if=/kernel of=/dev/sa0
works fine, but
$ dd if=datafile of=/dev/sa0 ibs=394 cbs=393 obs=32619 conv=ibm
dd: /dev/sa0: Input/output error
83+0 records in
0+0 records out
0 bytes transferred in 0.004842 secs (0 bytes/sec)
furthermore, drop the obs from the previous command, and things roll along
fine.
Any pointers?
