SCF Reference Manual for the Kernel Subsystem

The owner group number and user number of the $ZZKRN process is always the super ID (255,255).Subsystem

The current object state of $ZZKRN is always STARTED.Subsystem State

Configured
The number of generic processes that currently have at least one instance of the generic process
started.

STATUS SUBSYS Examples
1. This example displays the status of the $ZZKRN subsystem manager process. Of 12 processes
that have been configured, 10 are started.
-> STATUS SUBSYS $ZZKRN
NONSTOP KERNEL - Status SUBSYS \EAST.$ZZKRN
Name State Processes
(conf/strd)
$ZZKRN STARTED ( 12/10 )
2. This example displays the detailed status of the same $ZZKRN subsystem manager process
as in the preceding example:
-> STATUS SUBSYS $ZZKRN, DETAIL
NONSTOP KERNEL - Detailed Status SUBSYS \EAST.$ZZKRN
Primary PID.......... 1 , 51 Backup PID ........ 0 , 51
Subsystem Owner...... 255, 255 Subsystem State ... STARTED
Processes Configured. 12 Processes Started.. 10
STOP Command (Sensitive Command)
The STOP command terminates the activity of a ServerNet fabric in a normal manner. Upon the
successful completion of the STOP command, the ServerNet fabric is left in the STOPPED object
state.
You must be in interactive mode to use this sensitive command.
STOP [ / OUT file-spec / ] SERVERNET $ZSNET.{X|Y}.{cpu|*}
SERVERNET $ZSNET.{X|Y}.{cpu|*}
stops a ServerNet fabric (X or Y) in one or all processors. The variable cpu is the processor
number.
Considerations
• The asterisk (*) wild-card character in a STOP SERVERNET command specifies all available
processors.
• You cannot stop both ServerNet fabrics at the same time. If you attempt to do this, the operating
system keeps up the last path from processor 0 to processor 1 in the second fabric brought
down (shown in Example Step 2).
• For complete information about using this command when adding an enclosure or upgrading
memory, see the NonStop S-Series Hardware Installation and FastPath Guide, the appropriate
NonStop NS-series hardware installation guide, or the NonStop BladeSystem Hardware
Installation Manual.
• Because of the serious effects of this command, the operating system responds to a STOP
SERVERNET command with a confirmation request.
