Reboot node intentionally

Automatic recovery of a node

If you want to reboot a node or enable some configuration change that requires a reboot and have it recovered without auto recovery, check the auto recovery wait time. The auto recovery wait time is defined by the minimum value of minDiskWaitTimeForRecovery, metadataDiskWaitTimeForRecovery and dataDiskWaitTimeForRecovery. By default, minDiskWaitTimeForRecovery is 1800 seconds, metadataDiskWaitTimeForRecovery is 2400 seconds and dataDiskWaitTimeForRecovery is 3600 seconds. If the reboot is completed within the auto recovery wait time, it is safe to unmount the file system, shut down IBM Storage Scale, and reboot your node without having to disable auto recovery.

Manual recovery of a node

When you want to perform hardware maintenance for a node that must be shut down for a long time, follow the same steps mentioned in IBM Storage Scale Rolling Upgrade Procedure and perform hardware maintenance.
