Description
Notice that each instance has its own copy of the z/VM disks; they are in separate directories,
/z1 and /z2.
ISLINK
An ISLINK creates an ISFC (Inter-System Facility for Communications) connection. It is the
easiest link because it involves only CP commands and does not require a virtual machine or
userid. The VM system identifiers of the two connected systems must be different. Using the
devmaps shown above, the following commands (issued by MAINT, for example) activate the
link:
CP ACTIVATE ISLINK 0720 (command on ibmsys1)
CP ACTIVATE ISLINK 0720 (command on ibmsys2)
This should result in the message HCPALN2702I Link 0720 came up. The command Q ISLINK
can be used to display the status of the connection.
