I have an Elite 9 disk and a TTi CTS-2210 DLT drive on an Alphastation
250 4/266 running OSF v3.2. Each time I attempt to perform a dump of this
disk to the DLT drive, I get the errors listed below. All other local
partitions can be dumped fine (though admittedly none are 9Gb in size) and
remote 9Gb drives dump fine to this drive. The 9Gb drive in question can be
dumped without problem to a remote exabyte drive.
I have fsck'd the drive and no errors are found. Does anyone have
any idea what's up ?
# dump 0ucf /dev/rmt0h data2
dump: Dumping from host ltaxp1
dump: Date of this level 0 dump: Wed Feb 07 19:00:10 1996 GMT
dump: Date of last level 0 dump: the start of the epoch
dump: Dumping /dev/rrz1c (/data2) to /dev/nrmt1h

dump: Write error -- wanted to write: 10240, only wrote: -1
slave_work(): write(): I/O error
dump: Write error - /dev/nrmt1h, volume 1, 8992 feet -- cannot recover
dump: Cannot fopen /dev/tty for reading
query(): fopen(): No such device or address
dump: Cannot remove shared memory
remove_shared_memory(): shmctl(): Invalid argument
dump: SIGTERM received -- Try rewriting
dump: Unexpected signal -- cannot recover
Note:
1) I have tried various combinations of dump paramters involving
blocking factor/size/density to no avail.
2) The dump fails at different points in the tape each time - it is
not always 8992 feet as in the above example.
3) I have tried different tapes with no success.
4) I have tried different emulations on the DLT drive without
success (TK50, TZ87 and no emulation).
