EMC Fibre Channel with QLogic HBAs in the Linux x86 Environment
Installing and Configuring the HBA and Driver
Here is an example of this behavior:
To avoid this behavior and the delay that is incurred by Linux trying
to spin up the device, it is necessary to disable both the FailOver-
Mode and ArrayCommPath bit settings if PowerPath is not being
used.
If PowerPath is being used, ensure that both the FailOverMode and
ArrayCommPath bit settings are enabled. These settings are required
for PowerPath use.
Refer to the Navisphere Management software documentation for
instructions on how to disable these bit settings.
