NovaScale Blade 2021 Installation and User’s Guide
Installing a SCSI hard disk drive
The NovaScale Blade Server has two connectors on the system board for installing optional
Ultra320 SCSI hard disk drives.
Each Ultra320 SCSI connector is on the same bus. Depending on your NovaScale Blade Server, at
least one SCSI hard disk drive might already be installed. If your NovaScale Blade Server is
equipped with one SCSI hard disk drive, you can install an additional SCSI hard disk drive. These
two SCSI hard disk drives can be used to implement and manage a redundant array of independent
disks (RAID) level-1. See “Configuring a SCSI RAID array” on page 56 for information about SCSI
RAID configuration.
Attention: To maintain proper system cooling, do not operate the system unit without a NovaScale
Blade Server, expansion unit, or filler blade installed in each blade bay.
The following illustration shows how to install a SCSI hard disk drive and tray in the NovaScale
Blade Server.

Note
Do not install a SCSI hard disk drive in SCSI connector 1 (SCSI ID 1) if you intend to also install an
optional standard expansion card. The standard expansion card occupies the same area as the second
drive.
To install a SCSI hard disk drive, complete the following steps:
1. Read the safety information beginning on page iii and “Installation guidelines” on page 19.
2. Shut down the operating system, turn off the NovaScale Blade Server, and remove the
NovaScale Blade Server from the NovaScale Blade Chassis unit (see “Installing and removing
the NovaScale Blade Server from the NovaScale Blade Chassis unit” on page 20 for
instructions).
3. Carefully lay the NovaScale Blade Server on a flat, non-conductive surface.
