remote ufsdump permissions
Hi,

I have two solaris 9 boxes:
SunOS bmsapp01 5.9 Generic_118558-06 sun4u sparc SUNW,Sun-Fire-V440
and
SunOS bmsdb01 5.9 Generic_118558-06 sun4u sparc SUNW,Sun-Fire-V440.
The bmsapp01 server has a SDLT tape drive attached to it. I am trying to perform a remote ufsdump to the tape drive on bmsapp01 from bmsdb01.
I have performed this on other Sun server combinations successfully (backing up the database server to the tape drive on the application server) using the syntax from the command line as root on the database server:

ufsdump 0fuc - <filesystem> | rsh <applicationserver> dd of=/dev/rmt/0cbn

These machines are behind a very secure firewall so there has not been a problem with creating the .rhosts file in / on the application server.

However on the two Sun servers listed above, performing a remote ufsdump gives:

# ufsdump 0fuc - / | rsh bmsapp01 dd of=/dev/rmt/0cbn
DUMP: Date of this level 0 dump: Fri 09 Jun 2006 02:32:21 PM BST
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/md/rdsk/d10 (bmsdb01:/) to standard output.
dd: /dev/rmt/0cbn: open: Permission denied
DUMP: Mapping (Pass I) [regular files]
DUMP: Mapping (Pass II) [directories]
DUMP: Writing 63 Kilobyte records
DUMP: Estimated 10872978 blocks (5309.07MB).
DUMP: Dumping (Pass III) [directories]
DUMP: Broken pipe
DUMP: The ENTIRE dump is aborted.

The remote tape drive can be contacted from the database server and its status can be checked:

# rsh bmsapp01 mt -f /dev/rmt/0cbn status
Quantum Super DLT 320 tape drive:
sense key(0x7)= Write Protected residual= 0 retries= 0
file no= 0 block no= 0

The tape drive can be written to from the application server correctly using the ufsdump syntax:

bash-2.05# ufsdump 0fuc /dev/rmt/0bcn /
DUMP: Date of this level 0 dump: Fri 09 Jun 2006 02:41:04 PM BST
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/md/rdsk/d10 (bmsapp01:/) to /dev/rmt/0bcn.
DUMP: Mapping (Pass I) [regular files]
DUMP: Mapping (Pass II) [directories]
DUMP: Writing 63 Kilobyte records
DUMP: Estimated 16548348 blocks (8080.25MB).
DUMP: Dumping (Pass III) [directories]
DUMP: Dumping (Pass IV) [regular files]
DUMP: 16.95% done, finished in 0:48
DUMP: 34.01% done, finished in 0:38
DUMP: 47.56% done, finished in 0:33
DUMP: 61.64% done, finished in 0:24
DUMP: 77.43% done, finished in 0:14
etc...

So the tape can be written to locally, and its status can be checked remotely. However it cannot be written to remotely. The ufsdump is performed as root.
The entry in /.rhosts on bmsapp01 is + + and the permissions on /dev/rmt/0cbn are:

bash-2.05# ls -lt /dev/rmt/0cbn
lrwxrwxrwx 1 root other 45 May 31 2005 /dev/rmt/0cbn -> ../../devices/pci@1c,600000/scsi@1/st@5,0:cbn

The permissions on /devices/pci@1c,600000/scsi@1/st@5,0:cbn are:

bash-2.05# ls -lt /devices/pci@1c,600000/scsi@1/st@5,0:cbn
crw-rw-rw- 1 root sys 33,221 Jun 9 02:55 /devices/pci@1c,600000/scsi@1/st@5,0:cbn

Does anyone have any idea of why there is a permissions problem when performing a remote ufsdump and how this can be overcome?

Thanks in anticipation,

J
