NAME¶

fence_azure_arm - Fence agent for Azure Resource Manager

DESCRIPTION¶

fence_azure_arm is an I/O Fencing agent for Azure Resource Manager. It uses Azure SDK for Python to connect to Azure.

For instructions to setup credentials see: https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal

Username and password are application ID and authentication key from "App registrations".

NOTE: NETWORK FENCING
Network fencing requires an additional Subnet named "fence-subnet" for the Virtual Network using a Network Security Group with the following rules:
+-----------+-----+-------------------------+------+------+-----+-----+--------+
| DIRECTION | PRI | NAME | PORT | PROT | SRC | DST | ACTION |
+-----------+-----+-------------------------+------+------+-----+-----+--------+
| Inbound | 100 | FENCE_DENY_ALL_INBOUND | Any | Any | Any | Any | Deny |
| Outbound | 100 | FENCE_DENY_ALL_OUTBOUND | Any | Any | Any | Any | Deny |
+-----------+-----+-------------------------+------+------+-----+-----+--------+

When using network fencing the reboot-action will cause a quick-return once the network has been fenced (instead of waiting for the off-action to succeed). It will check the status during the monitor-action, and request power-on when the shutdown operation is complete.

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

Fencing action (Default Value: reboot)

-p, --password=[authkey]

Authentication key

-S, --password-script=[script]

Script to run to retrieve password

-n, --plug=[id]

Physical plug number on device, UUID or identification of machine This parameter is always required.
