+.TH fence_zvm 8 + +.SH NAME +fence_zvm - Power Fencing agent for GFS on System z z/VM Clusters + +.SH SYNOPSIS +.B +fence_zvm +[\fIOPTION\fR]... + +.SH DESCRIPTION +fence_zvm is a Power Fencing agent used on a GFS virtual machine in a System z z/VM cluster. +It uses the SMAPI interface to recycle an active image. + +fence_zvm accepts options on the command line as well as from stdin. +fence_node sends the options through stdin when it execs the agent. +fence_zvm can be run by itself with command line options which is useful +for testing. + +Vendor URL: http://www.sinenomine.net + +.SH OPTIONS +.TP +\fB-o --action\fP +Fencing action: "off" - deactivate virtual machine; "on" - activate virtual machine; "metadata" - display device metadata" - describe fence agent parameters; "status" - state of virtual machine +.TP +\fB--delay\fP \fIseconds\fP +Time to delay fencing action in seconds +.TP +\fB-n --plug\fP \fItarget\fP +Name of virtual machine to recycle. +.TP +\fB-h --help\fP +Print out a help message describing available options, then exit. +.TP +\fB-a --ip\fP \fIsmapi Server\fP +\fBName\fP of SMAPI server virtual machine. To be consistent with other fence agents this name is a little misleading: it is the name of the virtual machine not its IP address or hostname. +.TP +\fB--zvmsys\fP \fIz/VM System\fP +\fBName\fP of z/VM on which the SMAPI server virtual machine resides. Optional - defaults to system on which the node is running. +.TP +\fB-h --help\fP +Display usage information +.TP +\fI-t --timeout = < shutdown timeout >\fP +Amount of \fIgrace\fP time to give the virtual machine to shutdown cleanly before being +forcibly terminated. Currently, this option is ignored. + +.SH STDIN PARAMETERS +.TP +\fIagent = < param >\fP +This option is used by fence_node(8) and is ignored by fence_zvm. +.TP +\fIaction = < action >\fP +Fencing action: "off" - fence off device; "metadata" - display device metadata; "status" - state of device +.TP +\fIport = < target >\fP +Name of virtual machine to recycle. +.TP +\fIipaddr= < server name >\fP +\fBName\fP of SMAPI server virtual machine.

Currently, this option is ignored. + +.SH SEE ALSO +fence(8), fenced(8), fence_node(8) + +.SH NOTES +To use this agent the z/VM SMAPI service needs to be configured to allow the virtual +machine running this agent to connect to it and issue the image_recycle operation. +This involves updating the VSMWORK1 AUTHLIST VMSYS:VSMWORK1. file. The entry should look +something similar to this: + +.nf +Column 1 Column 66 Column 131 +| | | +V V V +XXXXXXXX ALL IMAGE_CHARACTERISTICS +.fi + +Where XXXXXXX is the name of the virtual machine used in the authuser field of the request. This virtual machine also has to be authorized +to access the system's directory manager. + +In addition, the VM directory entry that defines this virtual machine requires the +IUCV ANY statement (or IUCV <userid of SMAPI Server>). This authorizes use of IUCV +to connect to the SMAPI server. diff --git a/agents/zvm/fence_zvmip.c b/agents/zvm/fence_zvmip.c new file mode 100644 index 0000000..b16de48 --- /dev/null +++ b/agents/zvm/fence_zvmip.c @@ -0,0 +1,1001 @@ +/* + * fence_zvmip.c: SMAPI interface for managing zVM Guests + * + * Copyright (C) 2012 Sine Nomine Associates + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
