A single virtual machine can have 24,576 devices. This is an arbitrary
limit to control the amount of internal control blocks that take up main
memory below 2G.
A VM LPAR will support the number of real devices allowed to be defined via
IOCP to a single LPAR in subchannel set 0. This is
Hi,

the zVM information of the number of devices can zVM support. Will it be
any problems if I share the same IOCDS for zOS with zVM, where the number
of devices defined in the IOCDS more than 16384. (The number of
I guess it is 64K (from to ) The infoirmation probably is in

But, why define all z/OS devices to z/VM?
- It will consume some real storage in z/VM
- You might by accident format a volume in z/VM that z/OS is using.
- It costs some time to check them
I thought VP Q DASD will only show the CP and user defined owned volume list in
the system config ..
We have more than that in our disaster recovery environment and we
don't do anything to segregate VM from z/OS there.
So, VM is ok with that - it does take longer to IPL though.
For production, we separate out by LCU's (VM owns its own) and we
restrict the gen so that z/VM can't see the z/OS
Here, many of the devices (approximately 5000) are in the LPAR profile but
excluded from VM's configuration by being included in a Not_Accepted list in
SYSTEM CONFIG. That way, they do not cause the RDEVs to be built, but can be
added via command if we ever need to access them from VM.
