Hardware Service Procedure
SAS data cable replacement: NetBackup 5330 storage shelves
Document Number: 151
Version: 3.1 (6/14/16)
Purpose
This document describes how to remove and replace damaged or faulty NetBackup 5330 storage
shelf SAS data cables while the appliance is operating.
Affected Models
NetBackup 5330 Appliance
The NetBackup 5330 Appliance is a hardware and software storage system that scales to a total of
456TB of available backup capacity. It consists of a 2U NetBackup 5330 Appliance compute node
and one attached 4U NetBackup Primary Storage Shelf. You can add up to two optional 4U Expansion
Storage Shelves if you require additional storage.
The NetBackup 5330 Appliance compute node contains eight 3TB SAS disks, which can be accessed
from the front panel. An embedded RAID controller on the compute node's mainboard is used to
configure six of the eight disks into two RAID1 mirrored volumes, plus two hot-spare disks. These
volumes are labeled Volume 0 and Volume 1. If a disk in either RAID volume experiences a hardware
error, the appliance automatically initiates a RAID rebuild operation. During the rebuild operation, the
appliance randomly selects a hot-spare disk, and then rebuilds the RAID volume.
The disks in slot 6 and slot 7 are reserved for future use, while the slots 8 through 11 are empty.
A small control panel is on the right side of the front panel. It contains system LEDs and operations
buttons, including the power button.
