John,

I have seen this problem before. Did you add HSM on a alrady full filesystem?
I saw thta the reconcile never ended in that way.

Anyway did you hear the news that HSM on IRIX is no longer supported in TSM. So
i''l guess that you have to find something else. Same as us. How much data do
you have migrated that way?
We have about 800 GB in HSM.

Good luck,
