Renaming OpenVMS host

[ajbrehm]

I must have become rusty.

I am trying to rename an OpenVMS machine. modparams.dat change is done, sys$node_* is changed, net$configure.com and tcpip$config.com did their job, and ctrl-t confirms the new node name.

However, all devices still insist in being named after the old node name, including nodename$dka0 and several logicals use the old node name and refuse to change. What did I overlook?

   That's why people write stuff down.  And this new Inter-Web thing
makes finding such written-down stuff possible/practical.

   Hardware?  Software?

   My first guess:

      mcr sysgen show scsnode

      https://www.digiater.nl/openvms/freeware/v70/vmsfaq/vmsfaq_007.html

   Look for: "5.7 How do I change the node name of an OpenVMS System?"

No, did all that. Node name is changed, ctrl-t shows new node name.

Thanks for the tip about things written down. But the problem is what to do AFTER following those instructions with the symptoms described above?

For what it's worth, the problem was a combination of problems caused by queues and a problem with systartup_vms.com which does not reach starting TCP/IP if it runs into a missing queue first.

This method works:

Rename OpenVMS node
1. Edit systartup_vms.com to disable starting sys$batch.
• EDIT SYS$LOGIN:SYSTARTUP_VMS.COM
• Look (F1) for sys$batch and comment out
• $ START /QUEUE SYS$BATCH
• to look like
• $! START /QUEUE SYS$BATCH
• ctrl-z
• This is necessary for systartup_vms.com not to crash when the queue is missing.
2. Remove all queues, like sys$batch.
• STOP/QUEUE/NEXT SYS$BATCH
• DELETE/QUEUE SYS$BATCH
3. Modify SCSNODE value in modparams.dat and run autogen.com.
• EDIT SYS$SYSTEM:MODPARAMS.DAT
• ctrl-z
• @DKA0:[VMS$COMMON.SYSUPD]AUTOGEN
4. Rename node.
• RUN SYS$SYSTEM:SYSGEN
• SHOW SCSNODE
• SET SCSNODE “NEWNAME”
• WRITE CURRENT
• EXIT
5. Rename identifier sys$node_oldname to sys$node_newname.
• RUN SYS$SYSTEM:AUTHORIZE
• RENAME/IDENTIFIER SYS$NODE_OLDNAME SYS$NODE_NEWNAME
• EXIT
6. Reboot.
• REBOOT
7. After the reboot, log in via serial console and configure TCP/IP.
• @SYS$LOGIN:TCPIP$CONFIG
• Follow the menus, best to configure options 1-4 by pressing “A”
• Do not start TCP/IP until it is fully configured.
• Enable ssh client and server.
8. Log in via ssh and ctrl-t to test new name. Recreate batches like sys$batch.
• INIT/QUEUE/BATCH SYS$BATCH
• EDIT SYS$LOGIN:SYSTARTUP_VMS.COM
• Look (F1) for sys$batch and uncomment the line
• $! START /QUEUE SYS$BATCH
• to look like
• $ START /QUEUE SYS$BATCH
• ctrl-z
