Limit on serviceguard IP's?

[Philip Dunn_1]

Hi everyone,
Hopefully a quick question...

Is there a limit to how many IP's can be configured in the .cntl file?

I added a third and on trying to restart the package, serviceguard killed the server!

Is there anything special I need to do to add a new IP, or is it just a case of editing the .cntl file like when adding another logical volume to the cluster?

Thanks for any help

well you can certainly have more than 3 relocatable IP addresses in a package!
In fact the actual limit is up to 200 relocatable addresses per cluster, spread across however many packages you may have.
I suspect there was something else that caused your problem.

You simply add in any additional relocatabele address using the SUBNET/IP pair, remembering that it has to be set as an array, so your 3rd pair would be SUBNET[2]= and IP[2]=

Shalom Phil,

Check with your network administrator for IP's if the network is public. They tend to get crabby when IP addresses start to get used.

Thanks guys,
Maybe it didn't like me adding another LV and another IP at the same time.
We have added the LV, so will try again just adding the third IP.
I'll let you know the outcome and assign points a plenty...

Take the guessing out of why the system rebooted and investigate the crash that occured.
For instance,
- tail /etc/shutdownlog and get more detail.
- look at the bottom of OLDsyslog.log
- use q4 to analyze the dump files in /var/adm/crash that were created as a result of the crash and have HP read the analysis files. A document in the ITRC knowledge database tells how to run the q4 analyzer:

It was my fault, I was trying to add an IP to the package from a network that was not defined in the cluster config.

A quick shutdown of the cluster, added the network interface and IP on both nodes.

cmcheckconf -C .ascii
cmapplyconf -C .ascii

restart the cluster

added the new IP to the package and restarted.

Thanks for all your help
