You prevent reservation conflicts by having ONE host managing the access. So in TSM terms thats a library manager. "reserve_6" is now the default reservation type on AIX, and no atm I don't know what the difference is.
What is the difference between "reserve_6" and "persistent" reservation
types for tapes? How to prevent reservation conflict when more than one AIX
host share a SAN-attached tape drive/library?
# lsattr -Rl rmt0 -a reserve_type
reserve_6
persistent
