True. However, what happens if you stop all applications which have
open files (web server, whatever), then don't call SYSHUTDWN.COM at all?
This works for me. INSTALLED stuff will only be open on the node whose
system disk this is. One can dismount the system disk of a particular
node from all other nodes with no problem.
In other words, when shutting down node X:
On all other nodes, dismount all shadow sets with members with direct
connections only to node X (usually only system disks and swap/page
disks---otherwise I lose a shadow set when I lose a node, which is not
what I want).
On node X, dismount all shadow sets with members with direct connections
only to other nodes.
On ALL nodes, dismount all shadow set members with direct connections
only to node X. (If you have an ALPHA in the cluster which is not going
to reboot now, do this from that node with /POLICY=MINICOPY and make
sure that the subsequent MOUNT command (after the reboot) is also done
from an ALPHA, so that one gets a minicopy instead of a full copy.)
Depending on how fast the reboot is, what various system parameters are
set to, and whether or not WRITEs occur during the reboot, this might
not all be necessary, but I think it is sufficient.
