This is very strange. We've been told by IBM that inorder run anything
higher than OS/390 2.10, we had to go to a z box. We're currently running
OS/390 2.6 on a 9672 R83.
It's mostly semanticle. z/OS requires ALS-2 which is G5(9672-Rx6) or higher.
IIRC z/OS thru 1.6 runs in 31 bit on G5's. When you go to z/OS you
originally had 31/64bit choices or bimode migration aid(pay for). z/OS 1.7 requires
z/Box and only runs in 64 bit. It's a very large jump from 2.6 to z/OS anything.
AFAIK z/OS (as well as OS/390) requires ALS-1, which is G5 or higher.
ALS-2 is z/900 or higher.
z/OS thru 1.5 runs in 31-bit on G5's. 1.6 requires 64-bit machine.
Several persons just admitted they run z/OS on pre-G5 (pre-ALS1)
machines. IBM claims z/OS requires ALS1.
IMHO it is impossible several guys don't know their machine models.
Where is the true ?
*Official IBM* version is:
z/OS 1.6 and next requires 64-bit machine - z/900, z/800, z/990, z/890,
z9 (zMachine).
z/OS 1.1 thru 1.5 can run on zMachine - obvious.
z/OS 1.1 thru 1.5 can also run on 31-bit machines, *but* ALS-1 is
required. ALS-1 means G5, G6 and MP3000.
AFAIR OS/390 2.10 also needed ALS1.
