Device not being dismounted

[Swain]

$ dismount ALPHA$DKB600:
%DISM-W-CANNOTDMT, ALPHA$DKB600: cannot be dismounted
%DISM-W-INSTIMAGE, 5 images installed on volume
$ dismount/over=checks ALPHA$DKB600:
%DISM-I-INSTIMAGE, 5 images installed on volume
%DISM-I-MARKEDDMT, ALPHA$DKB600: has been marked for dismount
$ dismount/over=checks ALPHA$DKB600:
%SYSTEM-F-DEVNOTMOUNT, device is not mounted
$ mount/for ALPHA$DKB600:
%MOUNT-F-DEVMOUNT, device is already mounted

Why is it so, could someone explain?

Thanks,
Amaresh

$Help Dismount /Override=Checks will give you the answer

Specifically: "Note also that the file system cannot dismount a volume while any known file lists associated with it contain entries."

Until the 5 images are INSTALL REMOVEd, the disk is not fully dismounted.

Amaresh,

You should do a "install list" to see what's installed. Also, try doing a "show dev/file Alpha$Dkb600:" to see what that will show you.

You will have to un-install the images to have the disk dismount, but that may not be possible depending on what images are. You may need to shutdown the system.

None of what?

INSTALL REMOVE/DELETE makes the image unknown to subsequent image activations. Currently running images may have a reference to that (shareable) image. INSTALL REMOVE will only deinstall the image, if it is not referenced. In any other case it is "marked for deinstall". At image rundown there is a check if the reference count for such images became zero. If that's the case then, the image is deinstalled. Then you can dismount the disk.

INSTALL LIST does not list images "marked for deinstall".

show dev /files ALPHA$DKB600:
install list

Then from that information:
install remove blah blah

[Swain]

$ show dev /files ALPHA$DKB600:

The following worked.

show dev /files ALPHA$DKB600:
install list
INSTALL REMOVE

Thanks a lot to all!
