I posted this to freebsd-questions last Saturday but no one answered.
I guess I'll try hardware and scsi. Please excuse me if this is not
appropriate.
I was using dump to backup to a Exabyte 8700 (actually a 8505) 8mm
tape drive hanging off a Adaptec 1510 when the system hung. I could
not get any response from the console. I could ping the box but could
not login from telnet. The command I used was:
dump 0ubBf 128 14000000 /dev/nrst0 /mnt/u0 >>& log
/mnt/u0 is a 1.5G partition. Running the same command earlier on
smaller filesystems had no problem.
