Table: Response file variables specific to configuring disk-based I/O fencing

Variable

List or Scalar

Description

CFG{opt}{fencing}

Scalar

Performs the I/O fencing configuration.

(Required)

CFG{fencing_option}

Scalar

Specifies the I/O fencing configuration mode.

  • 1 - Coordination Point Server-based I/O fencing

  • 2 - Coordinator disk-based I/O fencing

  • 3 - Disabled-based I/O fencing

  • 4 - Online fencing migration

  • 5 - Refresh keys/registrations on the existing coordination points

  • 6 - Change the order of existing coordination points

  • 7 - Majority-based fencing

(Required)

CFG{fencing_dgname}

Scalar

Specifies the disk group for I/O fencing.

(Optional)

Note:

You must define the fencing_dgname variable to use an existing disk group. If you want to create a new disk group, you must use both the fencing_dgname variable and the fencing_newdg_disks variable.

CFG{fencing_newdg_disks}

List

Specifies the disks to use to create a new disk group for I/O fencing.

(Optional)

Note:

You must define the fencing_dgname variable to use an existing disk group. If you want to create a new disk group, you must use both the fencing_dgname variable and the fencing_newdg_disks variable.

CFG{fencing_cpagent_monitor_freq}

Scalar

Specifies the frequency at which the Coordination Point Agent monitors for any changes to the Coordinator Disk Group constitution.

Note:

Coordination Point Agent can also monitor changes to the Coordinator Disk Group constitution such as a disk being accidently deleted from the Coordinator Disk Group. The frequency of this detailed monitoring can be tuned with the LevelTwoMonitorFreq attribute. For example, if you set this attribute to 5, the agent will monitor the Coordinator Disk Group constitution every five monitor cycles. If LevelTwoMonitorFreq attribute is not set, the agent will not monitor any changes to the Coordinator Disk Group. 0 means not to monitor the Coordinator Disk Group constitution.

CFG {fencing_config_cpagent}

Scalar

Enter '1' or '0' depending upon whether you want to configure the Coordination Point agent using the installer or not.

Enter "0" if you do not want to configure the Coordination Point agent using the installer.

Enter "1" if you want to use the installer to configure the Coordination Point agent.

CFG {fencing_cpagentgrp}

Scalar

Name of the service group which will have the Coordination Point agent resource as part of it.

Note:

This field is obsolete if the fencing_config_cpagent field is given a value of '0'.

CFG{fencing_auto_refresh_reg}

Scalar

Enable the auto refresh of coordination points variable in case registration keys are missing on any of CP servers.
