Problem with LSM when first used

Hi Managers,

we bought a DS20E running Tru64 Unix 5.1 (PK3) recently. We ordered an
additional hard drive and a LSM license to do root disk mirroring.

I checked, that the LSM software is installed, that the license is
active, that LSM is present in the kernel (via devswmgr), and I made a
backup of the root disk via vdump and vrestore.

volencap and volreconfig ran successfully. However, the machine doesn't
reboot, it can't mount the filesystems, and the following error message
appears (I'm able to read it, when I boot into single user mode):

Starting LSM in boot mode
lsm:volio:Cannot open disk dsk0a: kernel error 16lsm:vold: WARNING Disk
root01 in group rootdg: Device not found.

The /etc/fdmns directory looks like this:
root_domain/rootdg.rootvol -> /dev/vol/rootdg/rootvol
usr_domain/rootdg.vol-dsk0g -> /dev/vol/rootdg/vol-dsk0g
var_domain/rootdg.vol-dsk0h -> /dev/vol/rootdg/vol-dsk0h

and the disklabel of dsk0 looks ok, with an AdvFS dsk0a, swap dsk0b,
LSMsimp dsk0e, and LSMnoprv dsk0h,f,g.

When I do a "grep lsm /etc/sysconfigtab" in this state, then I get:
lsm:
lsm_rootdev_is_volume = 2

which is strange, as it should be either 0 or 1, but not 2.

Fortunately, I was able to edit /etc/sysconfigtab, to edit the disklabel
of dsk0, and to restore the links in /etc/fdmns, and now the machine is
online again.

Any help is greatly appreciated.

Best regards,
Ralf Eichmann
