Hello again!
I turned out that the clu_bdmgr program has a bug.
It shifts the h partition off the disk by getting
a wrong disk size somewhere from a cache. This
occured when we upgraded from ACS8.5 to ACS8.6
(which, by the way, caused our controllers to
permanently reboot after patch 3, because it
conflicts with existent stripesets. We had to
clean out our complete EMA12000 to get that
working !). Compaq is currently working on it.
The only way to move a member boot_disk is to edit
the new disk by hand so that the cnx partition is h,
2048 bytes long and exactly aligned with the end of
the disk. After that, we configured the disk with the
clu_bdmgr -h dskxx /cluster/members/memberxx/boot_partition/etc/clu_bdmgr.conf
command for member boot with the old information.
It's also mandatory to safely zero out disklabels
with disklabel -rz on the HSG80 before writing them
with disklabel -rw and edit with disklabel -er,
otherwise unpredictable behaviour will occur.
