ADR

The Station Address of the •target" node for which the command is

 

intended. This address may apply to a local or remote node. When

 

specified, it is a 6"byte value and entered as 6 pairs of hexadecimal digits

 

separated by hyphens.

FileAddress

The File Server node's station address. This address may apply to a local

 

or remote node. When specified, it is a 6"byte value and entered as 6 pairs

 

of hexadecimal digits separated by hyphens.

LU#

The Logical Unit number of the card through which a command is

 

delivered to the target node (specified by ADR). LU# is always an LU in the

 

local system from which the command originates.

 

When you start NMGR (typically done in the Welcome file), it searches the

 

system I/O tables and builds a table of LAN LUs found on the system.

 

Thereafter, when you enter a Node Manager command without specifying

 

an LU, the lowest LU found in the LAN LU table is used as the default

 

value.

Each parameter applies to a particular LANIC card. In a given command, each parameter may, or may not be specified. The complexities arise because, for multiple LANIC cards installed, the default of one may depend on the value specified for another. Also, it may depend on whether the specified value applies to a local or remote node.

The defaults were designed to minimize network access or to make some logical sense. Note that most systems will contain a single LANIC card where command defaults are greatly simplified.

Group I: Commands Not Containing the FileAddress Parameter

One group of commands, referred to as Group I commands for discussion purposes, utilize the ADR and LU# parameters only (FileAddress is not a parameter in these commands). These commands are: RC, SC, UC, IM, DM, TC, EL, TEST, XID, RS, and ZS (for quick reference, see Appendix B).

Table 5"1 provides the ADR and LU# parameter defaults for this group of commands.
