Qualifying network LU names and commands
Qualifying LU names gives the system administrator the liberty of using the same name for LUs on different systems by adding the network identifier. This eliminates the necessity to have unique names for every LU on every system in your complex.
A network-qualified LU name consists of a network identifier of the originating system that is 1 to 8 characters long, a period, and then the LU name, which is 1 to 8 characters long. IMS™ commands that include network-qualified LU names must be enclosed in single quotes. For example: 'NETID001.LUAPPC02'. No blanks are allowed in a network-qualified LU name.
The parameter ALL for either the network identifier or the LU name cannot be substituted in a command for a network-qualified LU name. ALL cannot represent all of the LU names or all of the networks.
The LU name in the LU 6.2 descriptors can be network-qualified.
The network-qualified LU name is optional on commands that support the LUNAME keyword.
