The IBM Storage Scale FPO cluster

When a node reboots due to hardware or software issues, IBM Storage Scale can be started and the file system can be mounted if autoload is configured as yes in the mmchconfig command. In a typical FPO deployment, each node has several local attached disks. When a node stops functioning, disks attached to the node are made unavailable from the cluster.

Note: Do not reboot a node if the file system is still mounted.

After the node is rebooted, the disk status of the node is uncertain. The status of the node is dependent upon the auto recovery configuration (mmlsconfig restripeOnDiskFailure) and the IO operations over the cluster.
