If multiple disks fail and a RAIDset is broken
In the event of multiple disk failures on a single enclosure all backup data will be lost so it is very
important that if disk failures do occur they are dealt with swiftly and disks are replaced. This
section explains how to rebuild your storage in the event of a complete data loss. This should be
done under the guidance of HP 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
2. This will clean up all filesystem configuration and delete logical drives (LUNs) on all storage
devices.
WARNING! This command will completely remove all configured storage, and will run at
any time even if the storage is healthy.
3. After the delete command has completed rebuild the storage system using the following
StoreOnce CLI commands to discover and add storage to the system
hardware discover storage
hardware add storage
This will configure both the storage in the appliance (base storage) and any attached expansion
shelves. Licenses must be present for all attached storage before the command will complete
successfully. If insufficient licenses are available, no storage will be configured.
