Minidisks USERB can read data from USERA's 150 virtual disk whenever it issues a
read for data on its own 151 virtual disk.
You can link to any minidisk that is defined in theV8/370 directory
if that minidisk has a read and/or write password specified in theMDISK control statement and if the type of link you desire is allowed. Three
types of sharing may exist and, correspondingly, three passwords may be
specified in theMDISK record.
Minidisks may be shared in the following ways:• Read-only (R) indicates that all virtual machines sharing the disk
areusin9 it in read status. • Read/write (W) indicates that one virtual machine may have read/write
access and multiple virtual machines may have concurrent read-only
access.• Multi-write (MW) indicates that multiple virtual machines may issue
writes concurrently to the disk.Generally: of access requires that the virtual machines include code to control this, such
as the shared DASD support of os.See the description of the CP LINK !Qr
