The clusterXL_admin script can be used to initiate a manual fail-over from a cluster member.
This shell script registers a pnote (called admin_down) and gracefully changes the state of the given cluster member to Down (by reporting the state of that pnote as problem), or gracefully reverts the state of the given cluster member to Up (by reporting the state of that pnote as ok).
The clusterXL_admin script is located in $FWDIR/bin/ directory on your cluster members.
For more information, see sk55081.
Example:
#! /bin/csh -f # # The script will cause the machine to get into down state, thus the member will not filter packets. # It will supply a simple way to initiate a failover by registering a new device in problem state when # a failover is required and will unregister the device when wanting to return to normal operation. # USAGE: # clusterXL_admin <up|down>
set PERSISTENT = ""
# checking number of arguments if ( $#argv > 2 || $#argv < 1 ) then echo "clusterXL_admin : Invalid Argument Count" echo "Usage: clusterXL_admin <up|down> [-p]" exit 1 else if ( $#argv == 2 ) then if ( "$2" != "-p" ) then echo "clusterXL_admin : Invalid Argument ($2)" echo "Usage: clusterXL_admin <up|down> [-p]" exit 1 endif set PERSISTENT = "-p" endif
#checking if cpha is started $FWDIR/bin/cphaprob stat | grep "Cluster" > /dev/null if ($status) then echo "HA is not started" exit 1 endif
if ( $1 == "up" ) then echo "Setting member to normal operation ..." $FWDIR/bin/cphaconf set_pnote -d admin_down $PERSISTENT unregister > & /dev/null if ( `uname` == 'IPSO' ) then sleep 5 else sleep 1 endif
set stateArr = `$FWDIR/bin/cphaprob stat | grep "local"`
$FWDIR/bin/cphaprob stat | egrep "Sync only|Bridge Mode" > /dev/null #If it's third party or bridge mode, use column 4 , otherwise 5 if ($status) then set state = $stateArr[5] else set state = $stateArr[4] endif
echo "Member current state is $state" if ( $state != "Active" && $state != "Standby" ) then echo "Operation failed: member is still down, run 'cphaprob list' for further details" endif exit 0 endif
