Strange consvar problem


I've the following problem on single DS10 machine with two identical disks. On dsk1, Tru64 5.1B+PK3 is installed, on dsk0 there is a Tru64 4.0F installation. When booted on dsk1 in multi-user, I get the following error when I try to set the default boot device from dsk1 to dsk0:

# consvar -s bootdef_dev dsk0
prom_setenv:No such device:'/dev/disk/dsk0a'
Failed to set bootdef_dev

The device /dev/disk/dsk0a exists and I can't find anything wrong with.

Also, I am able to set the bootdef_dev variable correctly from the SRM console.

This problem has only occurred on a single DS10 machine- on all our other DS10 machines consvar works just fine.

Any advice is most welcome!

Please check that dsk0 is really there with:
hwmgr view device

and check that all special files are there with:
dsfmgr -VvF

Post results if not OK..

Hello Johan,

Thanks for the good advice, the hwmgr command immediately showed that there is no more dsk0c, instead it's now dsk2c.

After exchanging the devices using

dsfmgr -e dsk2 dsk0

everything works fine!
