Dissolve Shadow Set

Post by indy » Mon Sep 23, 2024 8:35 am

I am trying to dissolve a shadow set.
The disk used to be mounted at startup into a shadow set. I turned off the shadowing.
There is no shadow set defined. When I try to mount the disk, I get the message that I tried to mount a shadow set member and the disk is writelocked.
What is the solution? I do not see why this disk is "marked" as a member of a shadown set when there is no shadow set.

Assuming it is not the system disk (in that case, the procedure is slightly different) :

$ mount/over=(identification, shadow_membership) device:

SHADOW_MEMBERSHIP
"Allows you to override the write protection of former shadow set members. Applicable only if you have the volume shadowing option. See the VSI Volume Shadowing for OpenVMS. When you mount a volume with this qualifier, the volume shadowing generation number is erased. If you attempt to remount the volume in a shadow set, the volume is considered an unrelated volume and receives a full copy operation from a current shadow set member."
