Disk hung in "mounted dismount" state OPENVMS

[Karen Lee_3]

I have an openvms 7.3-2 system - I was trying to dismount a disk to make a change. there was an file open on that disk when I tried to dismount it. Now is says the state of the disk is "mounted dismount"...I cannot dismount it or remount it. Is there anything I can do other than reboot?

Karen,

The dismount should complete if/when you "close" the open file. What type(s) of file was open when you issued the dismount? If it was a user file, track down the "user" and have them close the file or $stop/id ;-). Page and swap files can be deinstalled. Installed images can be removed.

Karen,

You have to do show dev/files on all nodes to find the users of the disk.
And even when there is nothing, there might be other invisible things like spool files.

Did you try to DISMOUNT/ABORT ? This command cancels any outstanding IO.
Better is stop all processes which have some open files on the disk.

Users finally tracked down and files closed. Disk unmounted and remounted now

Thanks for all your help

Karen,

attached is a small DCL Routine, that when called with a diskname as P1 creates 3 DCL routines in SYS$LOGIN:

- UD_node_disk.INSFILES
deinstalles all installed images
- UD_node_disk.PROCESSES
stops all processes, which have files open on disk
- UD_node_disk.USER
does a reply to all users, which have open files

(messages are in german, but easy to change)

regards Kalle
