FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)

NAME

fence_wti - Fence agent for WTI

DESCRIPTION

fence_wti is an I/O Fencing agent which can be used with the WTI Network Power Switch (NPS). It logs into an NPS via telnet or ssh and boots a specified plug. Lengthy telnet connections to the NPS should be avoided while a GFS cluster is running because the connection will block any necessary fencing actions.

fence_wti accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_wti can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.

PARAMETERS

Fencing action (Default Value: reboot)
Force Python regex for command prompt (Default Value: ['RSM>', 'MPC>', 'IPS>', 'TPS>', 'NBB>', 'NPS>', 'VMR>'])
Identity file (private key) for SSH
-4, --inet4-only
Forces agent to use IPv4 addresses only
-6, --inet6-only
Forces agent to use IPv6 addresses only
IP address or hostname of fencing device This parameter is always required.
TCP/UDP port to use for connection with device (Default Value: 23)
Login password or passphrase
Script to run to retrieve password
Physical plug number on device, UUID or identification of machine This parameter is always required.
Use SSH connection
SSH options to use
Login name
Disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog.
Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity.
Level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e., on stdin).
Write debug information to given file
Display version information and exit
Display help and exit
Separator for plug parameter when specifying more than 1 plug (Default Value: ,)
Separator for CSV created by 'list' operation (Default Value: ,)
Wait X seconds before fencing is started (Default Value: 0)
Disable timeout (true/false) (default: true when run from Pacemaker 2.0+)
Wait X seconds for cmd prompt after login (Default Value: 10)
Test X seconds for status change after ON/OFF (Default Value: 20)
Wait X seconds after issuing ON/OFF (Default Value: 0)
Wait X seconds for cmd prompt after issuing command (Default Value: 3)
Sleep X seconds between status calls during a STONITH action (Default Value: 1)
Count of attempts to retry power on (Default Value: 1)
Path to ssh binary (Default Value: /usr/bin/ssh)
Path to telnet binary (Default Value: /usr/bin/telnet)

ACTIONS

Power on machine.
Power off machine.
Reboot machine.
This returns the status of the plug/virtual machine.
List available plugs with aliases/virtual machines if there is support for more then one device. Returns N/A otherwise.
List available plugs with aliases/virtual machines and their power state if it can be obtained without additional commands.
Check the health of fence device
Display the XML metadata describing this resource.

The operational behavior of this is not known.
Validate if all required parameters are entered.
