As usual many answers came very quickly.

Use
disklabel -e rz24c
which uses the 'c' partition instead of the 'a' partition.

Try to use the c-partition, not the a-partition, i. e.
disklabel -rw rz24c

You cannot change a partition that is currently in use. Make sure that none
of the partitions on that drive are mounted or being used as swap. You
might also have success if you use the "c" partition instead of the implicit
"a" partition the disklabel command normally uses.
disklabel -rw /dev/rz24c rz24
If that does not work, boot a Tru64 install CD. Early in the install
process -- before any writing is done -- the install software gives you a
choice which includes dropping into a root shell. Take it. Now create the
appropriate device and label it:
cd /dev
./MAKEDEV rz24
disklabel -z rz24
disklabel -rw rz24 rz24
halt
Now reboot from your backup root and restore your files.
Good luck!

I have a procedure which may help you out. This has been used extensively
by us for Dunix V4 systems. Good luck.

Now the disklabel is OK and I'm able to run everything from my backup root.
Thanks once more.
