Add Support For Read Only 3390 DASD When Running In LPAR

Maintenance of base and middleware on z/OS systems in my shop is performed on a master system. When new z/OS systems are created, these master volumes are copied to the new system. The cloned system LPARs quickly get out of sync with the master system. If we had the ability to make DASD read-only in LPAR, then we could simply overlay the cloned volumes with fresh copies without fear of overwriting something unique in that cloned system.

We have great success in this pattern using read-only MDISKs in z/VM.

    HCD allows for devices to be defined as READ-ONLY including Synchronous Peer-to-Peer Remote Copy (PPRC) secondary devices. Please refer to the z/OS HCD Planning documentation, chapter 2, topic ?Defining whether an I/O device is read-only? for more information.

    If this does not support your requirement, please elaborate on the functionality that is missing.

    Currently z/os does support read only devices if they are set up as a secondary in a pprc pair. The only issue is that we can't set the read only bit in the IODF without it being part of a PPRC pair. This causes issues in catalog writing serialization commands to a read only device. This should be an easy fix.
