VMS7.3-2 Impersonator

[Deepak kumar_3]

In VMS 7.3-1, the following command

$ ucx show interface/cluster

gives the node which is impersonator when issued only on the impersonator node.

but in VMS 7.3-2, this command is not working.

So could u please respond with how to find the impersonator node in the VMS 7.3-2. Hope someone will turn up soon.

Thanks & Regards
Deepak

Hi Deepak,
you could post TCP/IP version too.
Remember TCP/IP suite since V5.0 has renamed from UCX to TCPIP, so your command line could be:
$ tcpip show interface/cluster
About your trouble, VMS documentation has not made any change, so it seems qualifier /cluster works again.
Also, TCP/IP suite has inherit functionality by unix so you could use unix-style command as
$ TCPIP IFCONFIG -A
or if you have executed TCPIP$DEFINE_COMMANDS
$ ifconfig -a
You can receive furthermore help after you post TCP/IP version.

Bye

Yes now it is tcpip show interface/cluster
but in VMS 7.3-2 its giving error that
$ tcpip show inter/clus
%TCPIP-E-INTEERROR, error processing interface request
-TCPIP-I-NOMORE, parameter or qualifier CLUSTER no longer supported; see the doc
umentation for valid options and re-enter command.
but no were i am finding document how to get impersonater node .
$tcpip ifconfig -a will not give information regarding impersonater.

From the tcpip v5.4 RELEASE notes
http://h71000.www7.hp.com/doc/732FINAL/DOCUMENTATION/PDF/TCPIP054_RELNOTES.PDF

3.14 TCP/IP Management Command Restrictions
The following restrictions apply to the TCP/IP management commands:
â ¢ TCP/IP Services version 5.4 introduces failSAFE IP, which obsoletes the
IP cluster alias address. Consequently, the following TCP/IP management
commands are no longer supported:
â ¢ TCPIP SET INTERFACE /NOCLUSTER
â ¢ TCPIP SHOW INTERFACE /CLUSTER
To show interface addresses, including IP cluster alias addresses, you must
use the following sequence of DCL commands:
$ @SYS$MANAGER:TCPIP$DEFINE_COMMANDS.COM
$ if

yes with above(ie tcpip ifconfig -a) command we can find out the cluster alias IP for the same we can use this command also
$tcpip show config interface/cluster
with this can get cluster alias IP
But we can't get IMPERSNATOR node IP . Here in VMS 7-3.2 my problem is how to get impersonater node name/ip.

in this article
http://h71000.www7.hp.com/openvms/journal/articles/tcpip.html
it suggests doing the TCPIP SHOW INT/CLUS
command on every node in the cluster to determine which is the current cluster impersonator. Parhaps the same applies to the new command.

[Deepak kumar_3]

yes this document is saying that we can find out the impersonater node with this command but error is giving that it is not supported .

$ TCPIP SHOW INTERFACE/CLUSTER
%TCPIP-E-INTEERROR, error processing interface request
-TCPIP-I-NOMORE, parameter or qualifier CLUSTER no longer supported; see the doc
umentation for valid options and re-enter command

$ sh sys/noproc

have you tried
MCR SYSMAN SET ENV/CLUS
SYSMAN> do mcr SYS$SYSTEM:TCPIP$IFCONFIG.EXE "-a"
