Initial storage configuration
The disks in HP StoreOnce 4900 44 TB Capacity Expansion kits must be added to specific bays
in the drawers within the disk enclosure according to the sequence in which the disk set is being
added. Each drawer has a label that specifies the sequence in which each set of 11 disks must
be installed. This sequence is mandatory for StoreOnce software support.
