Hi admins,
Thanks to Andreas Maagdenberg for their replies.
Original question:
I have a two node Alpha cluster running Tru64 Unix v4.0D and TruCluster
Available Server v1.5
They both have two network cards, one network card is connected to the LAN,
and the other is only used as a heartbeat and so is connected to the other
node using a cross-over SCSI cable. The network configuration in the
cluster is as follows (changing names and IPs for security) :
Member name: node1
Member IP address: 196.4.82.100
Daemon communication use: Primary
Member aliveness ping use: Primary
Monitor interface setting: monitor
Member name: node2
Member IP address: 196.4.82.101
Daemon communication use: Primary
Member aliveness ping use: Primary
Monitor interface setting: monitor
(above taken from asecdb)
ASE Network Configuration
Member Name Interface Name Member Net Monitor
___________ ______________ __________ _______
node1 node1 Primary Yes
node2 node2 Primary Yes
(Taken from asemgr)
The public IPs are 171.42.44.1 for node1 and 171.42.44.2 for node2.
Besides we have a disk service named service1 and with IP 171.42.44.3
I wish to change the public IPs and the service IP to another subnet.
I know how to change the service IP but only it runs when the new IP is in
the same subnet that the other nodes IPs. I suppose I have to change the
nodes IPs and service IP to the new subnet at the same time.
Solution from Andreas:
"I suggest putting the service off-line.
Edit the hosts-file on both nodes. change the ip of the service.
As I see, you haven't configured the public network in ase and it's not
the hostname-network either so you can proceed with netsetup to
re-configure the public network.
After that you can bring the service online again.
I suggest (for private-net failover) that you also configure the public
network in ase as a backup network."
A remark:
I had also to change the IPs from /etc/hosts in each node that made
reference to the other node before that bring the service online. Netsetup
only changed the IPs for each node itself.
Best regards,
Jorge Grijalba
