Can't you assign each channel interface to a different LPAR? That used to work.
Aren't the assign and inassign commands for tape drives essentially the same a reserve and release for DASD? -- Shmuel (Seymour J.)

Tape drives are inherently shareable, but they do not use reserve/release. They use assign/unassign which works beyond sysplex boundaries. If a drive is assigned to one partition, it cannot be assigned by another on the same CEC or any other CEC. -- Phoenix Software International Edward E.
