How can I change Mom's name

[wakaka]

My machine’s hostname is ‘d003’, why I run a pbs script, the $PBS_NODEFILE display ‘d003.lan’?
My job runs abnormally because of that.

[boboshaq]

check entries in /etc/hosts

[wakaka]

The settings are correct.

Check the DNS settings; verify that nslookup <hostname> gives correct and consistent (across the nodes) answers. Also, check hostname -f. Furthermore, I believe MoM remembers the hostname when it started and isn’t updated if afterward the hostname changed for a reason; so you may need to restart the service.

I have restarted the service, it doesn’t work.

If you are using it for MPI jobs (hostsfile) you can read the contents of $PBS_NODEFILE and rewirte the file with the required hostnames

• is the machine part of the domain ?
• domainame command output

Try creating node as below:
qmgr -c "create node nodname Mom=nodename"

Delete first and add, it works.

But how can I change the order in range of d003-d005.

yes correct, if the node exists, then, you need to delete it first and add it again with the required Mom name configuration

• delete all the nodes and create them in the order you want it to be listed
