126 Removal and Replacement

Midplane (HP-Qualified Only)

The midplane board is replaceable by HP-qualified personnel only.

Replace the midplane based on troubleshooting results (see “Isolating Causes” in

chapter 4). Disks, LCCs, and power supply/fan modules connect to the midplane.

Caution Turning off a disk system isolates the enclosed disks from the host.

Perform recommended system administration to prevent loss of

pending I/Os to the disks.
