I had the same problem. Try this:
# /sbin/dump 0uBbf 1200000 10 /dev/nrst0 /[path]
* B = number of records per volume
* b = number of kilobytes per dump record
The above command allows me to dump all 6 partitions, about 500meg.
I too was curious as to just how many records fit on a 295 foot/
90M tape. Is this a fixed number? Specifying the BPI & total feet
on the tape won't work.
