IRIX 6.5.7, adsmclient 3.1.0.8, adsmserver 3.1.2.40.

Filesystem /ut (136Gb) corrupt, so the scenario is: mkfs, add HSM, restore
filesystem.....

#dsmmigfs add /ut :

End of story....

We had 'only' 300Gb HSM-data.......it's now 2 am we have an empty 136GB
filesystem without any (HSM)data.......

If anyone does have a golden idea, I'll invite you for a dinner next week
in Anaheim....

Cheers,
Henk ten Have (as a couple of times before, NOT amused about HSM, not on
               IRIX and not on AIX......)
