ServeRAID ROM Update Wizard
The IBM ServeRAID ROM (read-only memory) Update Wizard is a program
designed to automatically identify and scan each ServeRAID controller installed in
your server. If the BIOS and firmware code need updating, the wizard will give you
the opportunity to do so.
Device drivers
The device drivers are located in the following directory on the IBM ServeRAID
Support CD:
e:/operatingsystem/DRIVER
where eis the CD-ROM drive and operatingsystem is the specific operating system
used in the ServeRAID installation.
The device drivers are also located on the operating-system-specific IBM
ServeRAID Support diskettes.
ServeRAID Manager program
Use this program to configure arrays and logical drives using ServeRAID
controllers. ServeRAID Manager operates in two ways: in startable-CD mode and
as an installed program. In startable-CD mode, you can configure your ServeRAID
adapter before you install an operating system.
This program is available in the following directory:
e:/operatingsystem/MANAGER
where eis the CD-ROM drive and operatingsystem is the specific operating system
used in the ServeRAID installation.

Connector locations
This section provides illustrations of the SCSI channel connectors and cable
connectors for the ServeRAID-4H, ServeRAID-4Mx, ServeRAID-4Lx, and
ServeRAID-5i controllers.
The light-emitting diodes (LEDs) on the controllers indicate activity on the SCSI
channels and provide diagnostic information for trained service technicians.
ServeRAID-4H controller
The ServeRAID-4H controller has four independent SCSI channel connectors:
Channel 1, Channel 2, Channel 3, and Channel 4. Each of these SCSI channels
supports up to 15 physical devices.
Note: In the event of a power outage or failure, the battery-backup cache protects
the data stored in the ServeRAID cache memory when using the write-back
setting of the write-cache mode.
