Cluster aliase

Hello,

We have a four nodes cluster running on openvms 7.3-2. Now we need to remove two nodes from existing cluster.

I wanted to know how shall I check cluster aliases configured on decnet and IP and the procedure for removing the same.

NETCU> show version
TCPware(R) V5.7-2 Copyright (c) 2005 Process Software

OpenVMS version V7.3-2 booted on 7-JUL-2012 12:18:29.00,
running on a hp AlphaServer ES47 7/1150.

MAS number: <none entered in configuration>

NETCU> exit
PBK_RMSPR1>mc ncl
NCL>show ver

Node 0
at 2012-09-04-06:46:00.798+01:00Iinf

Characteristics

Version = T5.0.3

Thanks.

Hi Mrityunjoy,

if you are going to be removing/renaming the 2 removed nodes, then you do not need to take any specific action. Neither the IP alias, nor the Decnet alias, are associated with a list of nodes - so the aliases would now apply only to the remaining nodes.

If you need to specifically remove the IP alias, then see the TCPWare documentation:

http://www.process.com/tcpip/tcpware58docs/html/management/ch06.htm

In there you will see:

Use the REMOVE SECONDARY command in the NETCU Command Reference to remove an alias added through ADD SECONDARY. If the system holds a cluster lock, use the /ABORT qualifier to force removal of the secondary address.

For a guide to the DECnet cluster address, see section 9.2 of this guide:

http://h71000.www7.hp.com/doc/73final/6499/6499pro_019.html

I would expect that you would run NET$CONFIGURE on the removed nodes anyway, as part of your exercise to rename/reconfigure them.

Regards,

Duncan
