QLogic Fibre Channel adapters
When configured over QLogic Fibre Channel host bus adapters, the DiskReservation agent requires the Target Reset option of the adapter to be enabled. By default, this adapter option is disabled, causing the agent to hang during failover.
To workaround this issue
-
During system startup, press ALT+Q to access the QLogic adapter settings menu.
-
Select Configuration Settings.
-
Select Advanced Adapter Settings.
-
Set the Enable Target Reset option to Yes.
-
Save the configuration.
-
Repeat step 1 through step 5 for all QLogic adapters in each system.
-
Reboot the systems.
