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

NAME

fence_ifmib - Fence agent for IF MIB

DESCRIPTION

fence_ifmib is an I/O Fencing agent which can be used with any SNMP IF-MIB capable device.

It was written with managed ethernet switches in mind, in order to fence iSCSI SAN connections. However, there are many devices that support the IF-MIB interface. The agent uses IF-MIB::ifAdminStatus to control the state of an interface.

fence_ifmib accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_ifmib 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: off)
Set the community string
IP address or hostname of fencing device This parameter is always required.
TCP/UDP port to use for connection with device (Default Value: 161)
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.
Set authentication protocol (MD5|SHA)
Set privacy protocol password
Script to run to retrieve privacy password
Set privacy protocol (DES|AES)
Set security level (noAuthNoPriv|authNoPriv|authPriv)
Specifies SNMP version to use (1|2c|3) (Default Value: 2c)
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: 5)
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 snmpget binary (Default Value: /usr/bin/snmpget)
Path to snmpset binary (Default Value: /usr/bin/snmpset)
Path to snmpwalk binary (Default Value: /usr/bin/snmpwalk)

ACTIONS

Power on machine.
Power off 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.
