INFO PROCESS Command
ZPATH-ENT (path entry) is a structure that contains informa-
tion describing a particular path to the called system. This
structure is repeated 40 times. It contains the following
fields:
ZPATH-NUM is the path number of this path.
ZNOPASS-THRU is reserved for Tandem use only.
ZNEIGHBOR-NUM is the system number of the system immedi-
ately adjacent to the called system over this path.
ZPATH-LDEV is the logical device (LDEV) number of this
path.
ZTIME-FACTOR is the time factor of this path, which depends
on the number of lines per path and the configured line
speeds. (For more information about the time factor, refer
to the EXPAND Reference Manual .)
ZPATH-CPU-PIN is the CPU number (in bits 0 through 7)
and PIN number (in bits 8 through 15) of the line-handler
process that manages this path.
ZNUM-OF-LINES is the number of lines that make up this
path.
ZLINE-STATUS is a structure that describes a line in this
path. Since an EXPAND network allows a maximum of eight
lines in a path, this structure is repeated eight times.
ZLINE-STATUS consists of the following fields:
ZLINE-LDEV is the logical device (LDEV) number of this
line. A value of zero means that this is an empty entry
(there are no more lines).
ZSTATUS is the status of this line. This field can have
the following values:
ZEXP-VAL-READY The line is ready.
ZEXP-VAL-NOT-READY The line is not ready.
ZDOWN-CAUSE provides additional information about this
line if it is not ready. If the line is ready, the
value of this field is zero. If the line is not ready,
the value is a file-system error number indicating why
the line is not ready.
