Dear All

I've just installed a HP DDS-3 DAT drive on an Ultra 1/140
running SunOS 5.6. The DEC is running 4.0B. An attempt to
rdump from the DEC to the Solaris drive produces the following:

bash-2.01# rdump -0u -f titan:/dev/rmt/0 /dev/rrz4d
rdump: Dumping from host euler
rdump: Date of this level 0 dump: Tue Apr 28 15:22:34 1998 BST
rdump: Date of last level 0 dump: the start of the epoch
rdump: Dumping /dev/rrz4d (/export/user1) to /dev/rmt/0 on host titan
rdump: Mapping (Pass I) [regular files]
rdump: Mapping (Pass II) [directories]
rdump: Remote system is not known to be compatible for magtape
functions, output being treated as regular file
rdump: Estimate: 416168 tape blocks on disk
The available blocks(35122),is less than the estimated blocks(416168)
Dump is being aborted
rdump: SIGTERM received
rdump: The ENTIRE dump is aborted

For small filesystems (less than 35122 blocks) the dump works
OK and rrestore works fine too. For larger filesystems the
rdump fails as above. I first thought I could tell rdump the
size and density of the DAT drive, but it still fails:

bash-2.01# rdump -0u -s 30000 -d 61000 -f titan:/dev/rmt/0 /dev/rrz4d
rdump: Dumping from host euler
rdump: Date of this level 0 dump: Tue Apr 28 15:24:23 1998 BST
rdump: Date of last level 0 dump: the start of the epoch
rdump: Dumping /dev/rrz4d (/export/user1) to /dev/rmt/0 on host titan
rdump: Mapping (Pass I) [regular files]
rdump: Mapping (Pass II) [directories]
rdump: Remote system is not known to be compatible for magtape
functions, output being treated as regular file
rdump: Estimate: 416169 tape blocks on disk
The available blocks(35122),is less than the estimated blocks(416169)
Dump is being aborted
rdump: SIGTERM received
rdump: The ENTIRE dump is aborted

Notice rdump hasn't taken the slightest notice of these parameters,
maybe due to the compatibility problem mentioned.

I then tried the -B -S 300000 switches, but still no change.

Does anyone know how to fix this or can give any other suggestions ?

Many thanks

Ian
