Preparing for RAID160 SA Controller Installation
Before installing a RAID160 SA controller in a server, backup all data. This step is mandatory if the disks
were not previously configured on a RAID160 SA controller, because the data format will not be recognized
and the existing data will not be preserved.
Also, if you are connecting non-arrayed SCSI disk drives to a RAID160 SA controller, you must backup all
data, because data is not preserved when RAID controllers are connected to non-arrayed disk drives.
NOTE If your server supports Online Addition and Replacement (OL*) of the RAID160 SA controller
and you plan to do an online installation, see “Online Addition and Replacement” on page 39.
See the HP Smart Array RAID Controllers Support Matrix to find out if your server supports
OL*.
To prepare a server that does not support OL*, or if you would prefer to install the RAID160 SA controller
offline, follow these steps:
Step 1. Close all applications.
Step 2. Power down the server.
Step 3. Power down any peripheral devices that are attached to the server.
Step 4. Unplug the AC power cord from the outlet, and then from the server.
CAUTION In systems using external data storage, be sure that the server is the first unit powered down
and the last unit to be powered back up. Doing this ensures that the system will not
erroneously mark the disk drives as “failed”.
WARNING To reduce the risk of personal injury or damage to the equipment, consult the safety
information and user documentation provided with your server before attempting
installation.
Many computers are capable of producing energy levels that are considered
hazardous. These computers are intended to be serviced by qualified personnel
trained to deal with those hazards. Do not remove enclosures or attempt to bypass
any interlocks that may be provided for the purpose of removing these hazardous
conditions.
CAUTION Electrostatic discharge (ESD) can damage electronic components. Be sure that you are properly
grounded before continuing the installation procedure. See Appendix D, “Electrostatic
Discharge, on page 109, for ESD information.
The RAID160 SA controller contains electronic components that can easily be damaged by
small amounts of static electricity. To avoid damage, follow these guidelines:
Store the controller in its antistatic plastic bag until you are ready to install it
Work in a static-free area, if possible
