I am new to HACMP V5.4 in AIX5.3.Please let me know how to get the virtual IP address configured for a HACMP cluster.
Is this the correct way to identify it?
If i give ifconfig -a the first ip address displayed is the real address of the host.So the other one can be VIP.

Hello,
I would like to know if anyone has faced this problem. Whenever there is a duplicate IP address, HACMP goes down infact HACMP ( PowerHA ) takes the whole system down.
Does anyone know how to solve this problem ? (3 Replies)

Hi
I'm a little rusty with HACMP, but wanted to find out if it is possible to remove a disk heartbeat network from a running HACMP cluster.
Reason is, I need to migrate all the SAN disk, so the current heartbeat disk will be disappearing. Ideally, I'd like to avoid taking the cluster down to... (2 Replies)

crm_uuid
CRM_UUID(8) [FIXME: manual] CRM_UUID(8)
NAME
crm_uuid - get a node's UUID
SYNOPSIS
crm_uuid [-w|-r]
DESCRIPTION
UUIDs are used to identify cluster nodes to ensure that they can always be uniquely identified. The crm_uuid command displays and modifies
the UUID of the node on which it is run.
When Heartbeat is first started on a node, it creates a UUID (in binary form) in /var/lib/heartbeat/hb_uuid. This file can be read and
written by means of crm_uuid.
Note
There are very rare circumstances when crm_uuid should be used to modify the UUID file. The most common is when it is necessary to set
a node's UUID to a known value when creating a new cluster.
OPTIONS
--write, -w
Write a UUID value to the /var/lib/heartbeat/hb_uuid file.
Warning
Use the -w option with care, because it creates a new UUID value for the node on which it is run. Various scripts across the
cluster might still use the old value, causing the cluster to fail because the node is no longer associated with the old UUID
value. Do not change the UUID unless you changed all references to it as well.
--read, -r
Read the UUID value and print it to stdout.

/var/lib/heartbeat/hb_uuid
