Abstract:
1. A method to adjust error thresholds in a data storage and retrieval system, comprising the steps of: supplying a data storage and retrieval system comprising two storage controllers, each storage controller comprising a Fibre Channel switch, Fibre Channel initiator, storage logic, and memory, wherein said memory comprises a system device driver and microcode, wherein said microcode comprises one or more default error thresholds, and wherein said storage logic receives host commands, and host data payloads, and directs said host commands and host data payloads to a Fibre Channel switch with commands to provide said host commands to a Fibre Channel initiator, and to provide said host data payloads to one or more designated data storage devices, each data storage device comprises two Fibre Channel ports; determining if said memory comprises one or more operational error thresholds; operative if said memory comprises one or more operational error thresholds, operating said data storage and retrieval system using said one or more operational error thresholds; operative if said memory does not comprise one or more operational error thresholds, reading one or more default error thresholds from said microcode and setting those one or more default error thresholds as one or more operational error thresholds; wherein said default error thresholds comprise a maximum number of power system errors permissible during a designated time interval.
