SCF Reference Manual for the Kernel Subsystem
cpu
is a processor number or an asterisk (*) for starting all processors.
st
indicates the status of the path between the two processors and has one of these values:
(disabled) A ServerNet fabric is down at the “TO”
location. As a result, the path from the “FROM” processor
DIS
to the “TO” processor is down for receiving, which
means that the “TO” processor cannot receive from any
other processor or from I/O devices on that fabric. DIS
overrides UP and DN.
(down) The path from the FROM processor to the TO
processor is down because the path is failing. The FROM
DN
processor cannot communicate with the TO processor
on that fabric.
(across a row) The FROM processor is down or
nonexistent.
<-DOWN
The ServerNet fabric unexpectedly returned file-system
error nnn regarding the path from the FROM processor
to the TO processor.
Ennn
(across a row) The FROM processor unexpectedly
returned file-system error nnn to the ServerNet fabric.
ERRORnnn
For information about the file-system error, see the
Guardian Procedure Errors and Messages Manual.
(unavailable) The link from the FROM processor to the
“TO” processor is down because the TO processor is
down or nonexistent. UNA overrides all other values.
UNA
The path from the FROM processor to the TO processor
is up.
UP
START SERVERNET Examples
1. This example shows the results of starting the ServerNet X fabric in processor 0. Only the first
four processors are up in the system.
