If your system does not identify the SCSI Channel disks on your
LSI Logic Fusion-MPT adapter, check the following:
1. Is the disk enclosure powered ON?
2. Do the LEDs on the adapter indicate LVD operation? Refer to the
manual for the specific adapter to identify the correct operation of the
LED indicators.
3. Is the SCSI bus terminated at both ends (and only at the ends) with
LVD/SE terminators?
4. Does each SCSI disk have a unique SCSI ID that is different from
the host’s ID (host SCSI ID defaults to 7). For more information, see
Section 3.5, “Setting the SCSI Initiator ID,” page 10 .
5. Are all the disks on the bus LVD? If there is an HVD device on the
bus, no disks will show up and the LVD LED on the Fusion-MPT
adapter will blink.
If your system does not identify the Fibre Channel disks on your
LSI Logic Fusion-MPT adapter, check the following:
1. Is the disk enclosure powered ON?
2. Does the LED on the adapter indicate LINK? (LINK is valid only after
the device is probed.)
3. Does the LED on the switch or remote enclosure indicate LINK?
4. Does the LINK-SPEED parameter selected by the adapter match
that of the bus (1G, 2G or Auto)?
If you do not see disks, the following additional debug information may
help to identify the problem.
3.2 Verifying Correct Installation
Use this procedure to verify installation of your Fusion-MPT adapter in
the system.
1. Power on the system.
2. When the banner is displayed, press the Stop-A keys to interrupt the
boot process and stop at the ok prompt.
3. Use the show-devs command to list the system devices. You should
see an output similar to the following:
