HPE STOREONCE 5500

Disks in StoreOnce 5500 System 44 TB Capacity Expansion kits are 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.

Ordering the correct replacement disk for a failed disk
IMPORTANT:
HPE strongly recommends replacing a failed disk with a fresh disk from the factory. Do not substitute a
disk from another RAID set.
It is important to identify whether the disk is in the head unit or the attached shelf, because different disks are
used in the two locations and the carriers are different.
Always quote the serial number and product number for the enclosure that contains the failed disk so that
HPE Support can replace the correct part.

Identifying when a disk fails
WARNING:
It is important to replace a failed or predictive failed disk as soon as possible. Multiple disk failures within
the same array will result in complete data loss.
ALL enclosures of storage must be working for the system to operate; if the RAID fails on any one
enclosure due to exceeding the maximum number of failed disks in a pool then ALL data is lost.
