•
An Active-Active controller pair hangs during bootup drive scan (typically after
CT_Init
on the RS-232 display).
Verify that all SCSI channels are connected, cabled, and terminated porperly. Verify that the
controllers are set to their correct configuration.
•
An Active-Active controller pair hangs the host system during normal operation
or after failing over.
Verify that all SCSI channels are connected, cabled, and terminated properly.
•
An Active-Active controller pair always fails over after booting up.
Verify that the affected controller is set to its correct configuration. Verify the same SDRAM
DIMM sizes are in both controllers (Active-Active controllers require the same SDRAM DIMM
size).
•
One controller of an Active-Active controller pair displays the following message
when booting: "Other controller is attempting to reset this controller."
This message displays on failback if the failed controller has not been replaced. The message
continues to display whenever you boot the working controller and change its configuration.
To eliminate this message, replace the failed controller.
