Cartridges marked unavailable

[Lawrence Clark]

Hi:
I seeing a new situation where a number of volumes (K-type) are being set unavailable. 
This is stoppping reclamation of copypool volumes.

I generate a list, then mark then readw, then initiate a reclamation. The volumes then 
reset to unavailable, and the reclamation does not complete.

Any suggestions as to the reason wht.

Should I  check these out and mark these as destroyed?
