SCF Reference Manual for the Kernel Subsystem

The SERVERNET Object Type
You can use the SERVERNET object type to query and control the ServerNet X or Y fabric. The
value of object-name for the SERVERNET object type is:
{ $ZSNET | $ZSNET.{X|Y}.cpu }
$ZSNET
is the name of the ServerNet process. You use this form of object-name in the STATUS, VERSION,
and NAMES commands.
$ZSNET.{X|Y}.cpu
is the name of the ServerNet process, followed by the name of a ServerNet fabric (either X or
Y), and the one-digit or two-digit processor number of the processor logically connected to the
network. Use this form of the object-name when you want to specify a specific fabric and
processor.
Supported Commands
These commands use the SERVERNET object type:
NAMES START STATUS STOP VERSION
Consideration
Wild-card support for the SERVERNET object type is limited to use of an asterisk (*) in place of the
processor number.
Object Status
Object status for the SERVERNET object can be:
(disabled) A ServerNet fabric is down at the TO location. As a result, the path from the FROM
processor to the TO processor is down for receiving, which means that the TO processor
DIS
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 processor cannot communicate with the TO processor on that fabric.
DN
(across a row) The FROM processor is down or nonexistent.<-DOWN
The ServerNet fabric unexpectedly returned a file-system error regarding the link 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. For information about the file-system error, see the Guardian Procedure
Errors and Messages Manual.
ERROR nnn
(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
The path from the FROM processor to the TO processor was left up in order not to bring down
the last path between these two processors.

Examples
These are valid object names for the SERVERNET object type:
$ZSNET.X.0 == X fabric on processor 0
$ZSNET.Y.3 == Y fabric on processor 3
$ZSNET.Y.* == Entire Y fabric
