Considerations
•
The ALTER command is a sensitive command and can be used only by a super-
group user (255, n) ID.
•
If the FABRIC attribute is specified, the command requires confirmation by the
user.
•
Wild cards are not supported for the ALTER SWITCH command.
•
Only one attribute specification (FABRIC, LOCATOR, or BLINK) can be specified in
a single ALTER SWITCH command.
•
The BLINK ALL attribute specification blinks the LEDs of all ports, including the
fault LED, on the ServerNet II Switch component of the specified cluster switch.
ALTER SWITCH Command Examples
The following example changes the fabric setting of the nearest Y-fabric cluster switch
to none, meaning that the cluster switch can support neither the X nor the Y fabric:
> ALTER SWITCH $ZZSMN, NEAREST Y, FABRIC NONE
This command should only be issued by Compaq trained support personnel.
Executing this command will configure the switch with the specified
fabric setting (i.e., one of X, Y, or NONE). The NONE option should
normally be used only if the switch is being removed from the cluster.
The X and Y options should be used only if the current fabric setting
of the switch does not match the external fabric the switch is on.
Do you wish to continue with this command? (Y, [N]) Y
The nearest ServerNet switch in the external ServerNet Y fabric
now has a fabric setting of NONE.
The following example sets the locator string for the nearest Y-fabric cluster switch to a
new value:
> ALTER SWITCH $ZZSMN, NEAREST Y, LOCATOR "Building 3, Room 1346"
The nearest ServerNet switch in the external ServerNet X fabric now has a
switch locator string of:
"Building 3, Room 1346"
ALL Blink all switch port LEDs, including the fault LED.
NONE Stop blinking all switch port LEDs, including the fault LED, and
restore the normal operating state of the LED. (During normal
operation, the port LED lights to indicate link alive.)
