Rename OpenVMS Node

Rename OpenVMS node. Please note: If the node you are renaming uses DECnet, you must re-configure DECnet after the name change.

1. Edit systartup_vms.com to disable starting sys$batch.

EDIT SYS$MANAGER: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 and SCSSYSTEMID values 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.
