Troubleshooting 7-17 I If the array controllers have already been set to Multibus_Failover mode, then check the integrity of the components along the unseen Fibre Channel Fabric path. Do the following: G Confirm that the Compaq KGPSA device driver was properly installed. Refer to "Installing Secure Path Software for Windows 2000" in Chapter 5, "Installation and Configuration." G Check the status LEDs on the host adapter for error indications. G Verify that the Fibre Channel cable has been properly installed between the host adapter and its Fibre Channel SAN Switch. G Check the status LEDs on the Fibre Channel SAN Switch ports for error indications. G Verify that the Fibre Channel cables have been properly installed from the Fibre Channel SAN Switch to both ports on the array controller. G Use the CLI to obtain status information about the array controller. Verify that both port 1 and port 2 on each array controller are active.

■
If the array controllers have already been set to Multibus_Failover
mode, then check the integrity of the components along the unseen Fibre
Channel Fabric path. Do the following:
G
Confirm that the Compaq KGPSA device driver was properly
installed. Refer to
“
Installing Secure Path Software for Windows
2000
”
in Chapter 5,
“
Installation and Configuration.
”
G
Check the status LEDs on the host adapter for error indications.
G
Verify that the Fibre Channel cable has been properly installed
between the host adapter and its Fibre Channel SAN Switch.
G
Check the status LEDs on the Fibre Channel SAN Switch ports for
error indications.
G
Verify that the Fibre Channel cables have been properly installed
from the Fibre Channel SAN Switch to both ports on the array
controller.
G
Use the CLI to obtain status information about the array controller.
Verify that both port 1 and port 2 on each array controller are active.
For a Redundant Fibre Channel Arbitrated Loop
If the cluster node cannot see all of the storagesets that are configured to the
FC-AL paths, do the following:
■
Verify that the array controllers on the unseen path are set for
Multibus_Failover mode. If an array controller has not been set to
Multibus_Failover mode, then the cluster nodes will only see the
storagesets that are configured to the other array controller in the storage
subsystem.
