Below are the master triggers conditions. Bit[3] Trigger condition for Device Removal event Bit[2] Trigger condition for TM command issued by driver Bit[1] Trigger condition for Adapter reset issued by driver Bit[0] Trigger condition for IOC Fault state During driver load: If Master trigger type bit is enabled in the Persistent Trigger Page0 then read the Persistent Trigger Page1 and update the ioc instances diag_trigger_master.MasterData with Persistent Trigger Page1's MasterTriggerFlags. This will restores the Master trigger type's triggers which are enabled before. When user modifies the Master trigger type triggers: When user sets/clears the Master trigger type triggers then driver fisrt checks whether IOC firmware supports trigger pages support or not. if firmware supports these pages then driver enables the Master trigger type bit in Persistent Trigger Page0 (if it was not enabled before) and updates the user provided trigger values in Persistent Trigger Page1.
