15 Storage management
This chapter describes:
• The storage RAID configuration
• How to identify a failed disk
• How to replace a disk
• How to rebuild the RAID if several disks fail
• How to expand storage after adding a new shelf
• How to expand storage using a previously configured shelf
RAID configuration
The HP StoreOnce Series Backup system uses RAID 6 storage devices. RAID 6 provides protection
against double disk failures and failures while a single disk is rebuilding. This means that one disk
can fail within each pool or 6–disk array and the system will continue to function correctly. Once
the failed disk is replaced, the RAID rebuilds automatically.
HP StoreOnce 6500 Backup system
• Server nodes: two disks in each node mirror each other. If one fails, the system will continue
to function correctly. The failed disk should be replaced as soon as possible. The presence of
a replacement disk invokes the Smart Array Automatic Data Recovery (ADR) feature to rebuild
the replaced drive.
• Disk enclosures: the HP StoreOnce 6500 Backup system has two disk enclosures with base
storage of 11 disks for user data + 4 hot spare disks. Up to five Capacity Epansion kits may
be added to the disks in each disk enclosure to increase the backup data capacity, also RAID
6. These disks are configured in RAID 6 pools, such that two disks per pool can be lost without
loss of backup data.
HP StoreOnce B6200 Backup system:
• Server nodes: two disks in each node mirror each other. If one fails, the system will continue
to function correctly. The failed disk should be replaced as soon as possible. The replacement
disk invokes the Smart Array Automatic Data Recovery (ADR) feature to rebuild the replaced
drive.
• Storage array controllers: each controller has two arrays, each with six disks. One disk may
fail in each array without affecting system functions. The failed disk(s) should be replaced as
soon as possible.
• Capacity upgrade shelves: each shelf has two arrays, each with six disks. One disk may fail
in each array without affecting system functions. The failed disk(s) should be replaced as soon
as possible.
Identifying a leftover disk
WARNING! Recover or replace leftover disks as soon as possible. Leftover disks remain unused
by the storage system and do not provide any level of redundancy. Subsequent disk failures within
the same pool or array can result in complete data loss.
If you configured recipients for SNMP traps or email alerts, they will be notified of disk status
changes. Use the Hardware page of the GUI to find detailed information; see
“Hardware” (page 128). The disk fault LED (amber) will also be illuminated on the disk carrier.
