Converting SCSI From Simplex to Duplex

Convert to Duplex

To convert to duplex, perform the following steps:
Step 1. Remove the SCSI Jumper Cable. A SCSI jumper cable bridges the two SCSI connectors on the SCSI backplane
when the server is configured for simplex operation. This jumper must be removed in order to install the duplex
board and to connect the SCSI B cable. See Figure 4-18, "Removing the SCSI Jumper Cable."

Step 2. Install the duplex board. The duplex board is installed in the SCSI connector located nearest the disk drive cage.
The duplex board is shipped with a duplex board bracket attached. When the duplex board is properly installed, it
is secured to the disk drive cage by the bracket and to the SCSI backplane board by the SCSI connector sockets.
See Figure 4-19, "Installing the Duplex Board."
NOTE
66
In simplex mode, both hard disk drives, slot 0 and slot 1, are driven by SCSI channel A. When the
duplex board is installed, slot 1 hard disk drive is now driven by SCSI channel B. If HP-UX was
previously installed and "whole disk vxfs" was not used, the system will no longer boot. Refer to
the HP-UX Installation Guide for further information.
