You can use Linux FailSafe to reset nodes in a cluster. This sends a
reset command to the system controller port on the specified node. When the
node is reset, other nodes in the cluster will detect this and remove the
node from the active cluster, reallocating any resource groups that were allocated
on that node onto a backup node. The backup node used depends on how you have
configured your system. Once the node reboots, it will rejoin the cluster. Some resource groups
might move back to the node, depending on how you have configured your system. To reset a Linux FailSafe node using the Cluster Manager GUI, perform
the following steps: On the left side of the display, click on the “Nodes
& Cluster” category. On the right side of the display click on the “Reset
a Node” task link to launch the task. Enter the node to reset. Click on “OK” at the bottom of the screen to complete
the task.
When Linux FailSafe is running, you can reboot a node with the following
Cluster Manger CLI command: This command uses the Linux FailSafe daemons to reset the specified
node. You can reset a node in a cluster even when the Linux FailSafe daemons
are not running by using the standalone option of the admin reset command of the CLI: cmgr> admin reset standalone node A |
This command does not go through the Linux FailSafe daemons. Linux FailSafe Administrator's Guide
