Option 3: Connect cable to port on host SAS controller and replace existing SAS
cable
The following instructions are valid for some ProLiant servers.
NOTE:
This option is not recommended for Gen8 or Gen9 servers because you lose the use
of all four hard drive bays.
This installation uses the HPE SAS split cable to replace one of the existing SAS cables from
the host SAS controller to the server SAS hard disk drive bays. The SAS data cable has four
data paths; this configuration diverts the wiring from one of the hard disk drive bays to the tape
drive. You may lose the use of a hard disk drive bay with this cabling solution.
CAUTION:
Do
NOT
use this option with RAID configurations.
1.
Remove the plastic covers from both connectors on the supplied mini-SAS cable. You will
need to use the SAS connector on the second branch of the cable for this installation.
2.
Hewlett Packard Enterprise strongly recommends that the tape drive is connected to the
second SAS port on the host controller, which is the port that connects to the hard disk drive
bays with the highest numbers. Look at the front of the server and establish which SAS cable
is connected to the hard disk drive bays with the highest numbers.
Cable routing varies from one server to another. You may need to remove other components,
such as fan banks, while you work with the cable. Always refer to your server documentation
for server-specific cabling instructions.
CAUTION:
It is not possible to identify which disk drive bay will be lost for all servers (it
is normally the highest-numbered disk bay). The only way to be sure, is to check the disk
LEDs after installing the tape drive. For this reason, you should never attempt this installation
if you have a disk RAID configuration.
3.
Remove the existing SAS cable.
