Check for cluster over IP

Post by brianreiter » Wed Jul 31, 2024 3:38 am

Hi Folks,

Is there an easy way to check if a cluster is using IP or not?

I'm planning to upgrade a couple of of Itanium dual nodes clusters to the latest version of VSI and I don't want to break the cluster information.

cheers

Brian

Check if the kernel parameter NISCS_USE_UDP is set to 1;

If NISCS_USE_UDP is set to 1, the PEdriver uses IP in addition to the LAN driver for cluster communication. The bit setting of 1 loads the IPCI configuration information in the configuration files, which are loaded during the boot sequence. SYS$SYSTEM:PE$IP_CONFIG.DAT and SYS$SYSTEM:TCPIPCLUSTER.DAT are the two configuration files used for IP Cluster interconnect.

Brilliant that helps a lot.

So I've got a mix of configurations for the various clusters, but at least I now know what to expect.
