Option 3: Connect cable to port on host SAS controller and replace existing SAS
cable
The following instructions are valid for some HP ProLiant servers.
This installation uses the HP 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 data paths;
this configuration diverts the wiring from one of the hard disk drive bays to the tape drive. You
should be aware that 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. HP 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 installating 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.
