22 Determine if there is an excessive amount of network traffic to one or more RAID controller modules. This problem is self-correcting because the EMW software periodically retries to establish communication with the RAID controller modules in the storage array. If the storage array was unresponsive and a subsequent try to connect to the storage array succeeds, the storage array becomes responsive. For an out-of-band managed storage array, determine if management operations are taking place on the storage array from other storage management stations. A RAID controller module-determined limit exists to the number of Transmission Control Protocol/Internet Protocol (TCP/IP) connections that can be made to the RAID controller module before it stops responding to subsequent connection attempts. The type of management operations being performed and the number of management sessions taking place together determine the number of TCP/IP connections made to a RAID controller module. This problem is selfcorrecting because, after some TCP/IP connections terminate, the RAID controller module then becomes responsive to other connection attempts. 23 If the storage array is still unresponsive, a problem might exists with the RAID controller modules. Contact your Technical Support representative.
