STOP Command
STOP Command
The STOP command terminates the execution of the operational firmware in the
specified ServerNet/FX adapter. The LBU is reset to the STOPPED summary state.
STOP is nearly identical to the ABORT command. Unlike ABORT, however, STOP
terminates a ServerNet/FX adapter only if the adapter is in a STARTED state. STOP is
a sensitive command.
The STOP command syntax is
OUT file-spec
causes any SCF output generated for this command to be directed to the specified
file.
LBU
is a keyword specifying that an LBU name comes next on the command line.
LBU-name
is the name of the LBU ($ZZFOX.#X or $ZZFOX.#Y) associated with the
ServerNet/FX adapter to be stopped.
Considerations
•
STOP terminates activity in the ServerNet/FX adapter only if the adapter is in the
STARTED summary state. Use the ABORT command for all summary states
except UNKNOWN. Refer to Figure 4-1 on page 4-18 to see the ABORT and
STOP commands compared to the DISCONNECT and CONNECT commands.
•
If the processor is still powered on, a stopped ServerNet/FX adapter still passes
packets through to its neighbor, but the ServerNet/FX adapter doesn’t
resynchronize or otherwise process the packets. This procedure is called hardware
passthrough mode. If you issue the DISCONNECT command for the left and right
sides of the ServerNet/FX adapter, then no packets passthrough the ServerNet/FX
adapter.
Example
To fully stop a FOX cluster, issue the following two commands:
SCF> STOP LBU $ZZFOX.#X
SCF> STOP LBU $ZZFOX.#Y
STOP [ /OUT file-spec/ ] LBU LBU-name
