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.

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

Forces agent to use IPv6 addresses only

-a, --ip=[ip]

IP address or hostname of fencing device This parameter is always required.

-u, --ipport=[port]

TCP/UDP port to use for connection with device (Default Value: 44444)

-m, --method=[method]

Method to fence (onoff|cycle) (Default Value: onoff)

-p, --password=[password]

--login-timeout=[seconds]

Wait X seconds for cmd prompt after login (Default Value: 5)

--missing-as-off

Missing port returns OFF instead of failure (Default Value: 1)

--power-timeout=[seconds]
