If you started the host system before you were connected to the RAID controller module in the storage array, the Host Context Agent software will not be able to detect the RAID controller modules. If this is the case, make sure that the connections are secure, and restart the Host Context Agent software.

19If you have recently replaced or added the RAID controller module, restart the Host Context Agent software so that the new RAID controller module is recognized.

20If the problem still exists, make the appropriate host modifications, check with other administrators to see if a firmware upgrade was performed on the RAID controller module from another storage management station.

If a firmware upgrade was performed, the EMW on your management station might not be able to locate the new AMW software needed to manage the storage array with the new version of the firmware.

21If the problem persists contact your Technical Support representative.

22Determine 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 attempt 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 self- correcting because, after some TCP/IP connections terminate, the RAID controller module then becomes responsive to other connection attempts.

23If the storage array is still unresponsive, a problem might exist with the RAID controller modules. Contact your Technical Support representative.
