Rebuilding storage if multiple disks fail and a RAIDset is broken
This section explains how to rebuild your storage in the event of a complete data loss. This should
be done under the guidance of HPE Support.
After the failed disks have been replaced it will be necessary to remove the old filesystem
configuration and rebuild a new one as follows:
1. Use the following StoreOnce CLI to remove all configured storage on the appliance (except
that used by the operating system):
hardware delete storage all
WARNING! This command will completely remove all configured storage, and will run at
any time even if the storage is healthy.
2. This will clean up all filesystem configuration and delete logical drives (LUNs) on all storage
devices.
