I got some clarification on why my HSM client data
can't be migrated from an MVS ADSM server to a UNIX
server.  According to the Tivoli guys a UNIX server is
not going to be able to read the EBCDIC tape format
from the MVS system - so apparently *all* data on the
tapes will be poo-poo.   We'll be starting from
scratch - all history will be lost.  Doesn't seem
right.
