Replacing an existing SAS hard drive cable
The following instructions are valid for some HPE ProLiant servers.
This installation uses the HPE SAS split cable to replace one of the existing SAS cables from the host
SAS controller to the server's SAS hard disk drive bays. The SAS data cable has four datapaths; this
configuration diverts the wiring from one of the hard disk drive bays to the tape drive. You might lose the
use of a hard disk drive bay with this cabling solution.
CAUTION:
Do NOT use this option with RAID configurations.
Procedure
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 (this 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.
