I guess it is 64K (from 0000 to FFFF) The infoirmation probably is in the z/VM General Information manual.
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 when z/VM is IPLed, and shut down - A CP Q DASD will yield a very long result I guess you would use address ranges for DASDs for use by z/VM, so define only these ranges to the z/VM partitions. 2008/10/31 Yee Fong Ooi <[EMAIL PROTECTED]>: > > Hi, > I am new in zVM world.
