This syntax:
ufsdump 0fuc <appserver>:/dev/rmt/0cbn <filesystem>
works on one of our combinations of application and database server.
However on the application and database server combination that has caused me to open this thread, this what happens:
# mt -f bmsapp01:/dev/rmt/0cbn status
bmsapp01:/dev/rmt/0cbn: No such file or directory
Please note though, on the same server as mentioned originally in the call:
# rsh bmsapp01 mt -f /dev/rmt/0cbn status
Quantum Super DLT 320 tape drive:
sense key(0x0)= No Additional Sense residual= 0 retries= 0
file no= 0 block no= 0
The rsh method is successful in getting the mt -f status command to work.
However it is not possible to get ufsdump to work using rsh:
# ufsdump 0fuc - / | rsh bmsapp01 dd of=/dev/rmt/0cbn
dd: /dev/rmt/0cbn: open: Permission denied
DUMP: Date of this level 0 dump: Sun 11 Jun 2006 03:36:51 PM BST
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/md/rdsk/d10 (bmsdb01:/) to standard output.
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.
So, I can get the remote working on other combinations of application and database server, but not this one.
Does anyone have any suggestions?
Thanks in anticipation,
Jabberwocky

cvcd(1M) System Administration Commands cvcd(1M)
NAME
cvcd - virtual console daemon
SYNOPSIS
/platform/platform_name/cvcd
DESCRIPTION
The virtual console daemon, cvcd, is a server process that supports the network console provided on some platforms. The cvcd daemon accepts
network console connections from a remote host (only one host at any given time). Console input is read from this connection and forwarded
to cvc(7D) by way of cvcredir(7D).
Similarly, console output is read from cvcredir(7D) and forwarded across the network console connection. If cvcd dies, console traffic is
automatically rerouted through an internal hardware interface.
The cvcd daemon normally starts at system boot time. Each domain supports only one cvcd process at a time.
Caution: On Sun Enterprise 10000 domains, cvcd uses a configuration file (/etc/ssphostname) to determine the name of the host from
which network console connections are allowed. If the remote console host is renamed, you must edit the configuration file
to reflect that change.
OPERANDS
The following operands are supported:
platform_name The official Sun platform name used in packaging and code. For example, for Sun Fire 15K servers, the platform_name
would be SUNW,Sun-Fire-15000.

NOTES
The cvcd service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/cvc
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
