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

NAME

fence_zvmip - Fence agent for use with z/VM Virtual Machines

DESCRIPTION

fence_zvmip is a Power Fencing agent for z/VM SMAPI service via TCP/IP.

The z/VM SMAPI service must be configured so that the virtual machine running the agent can connect to the service, access the system's directory manager, and shortly thereafter run image_deactivate and image_activate. This involves updating the VSMWORK1 NAMELIST and VSMWORK1 AUTHLIST VMSYS:VSMWORK1 files.

The NAMELIST entry assigns all the required functions to one nick and should look similar to this:

:nick.ZVM_FENCE
:list.
IMAGE_ACTIVATE
IMAGE_DEACTIVATE
IMAGE_STATUS_QUERY
CHECK_AUTHENTICATION
IMAGE_NAME_QUERY_DM

The AUTHLIST entry authorizes the user to perform all the functions associated with the nick, and should look similar to this:

Column 1 Column 66 Column 131

| | |
V V V

XXXXXXXX ALL ZVM_FENCE

where XXXXXXXX is the name of the user in the authuser field of the request.

Refer to the official z/VM documentation for complete instructions and reference materials.

fence_zvmip accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_zvmip 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)
-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: 44444)
Method to fence (onoff|cycle) (Default Value: onoff)
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 SSL connection with verifying certificate (Default) (Default Value: 1)
Use SSL connection without verifying certificate
Use SSL connection with verifying certificate
Login name This parameter is always required.
Don't use SSL
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)
Missing port returns OFF instead of failure (Default Value: 1)
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: 5)
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 gnutls-cli binary (Default Value: /usr/bin/gnutls-cli)

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.
