14 Remove the host with the Unresponsive status from the EMW, and select Add Storage Array to add the host again. 15 If the host does not return to Optimal status, go to step 16. 16 Ensure that the host is turned on and operational and that the host adapters have been installed. 17 Check all external cables and switches or hubs to make sure that no visible damage exists and that they are securely connected. 18 Make sure the host context agent software is installed and running. If you started the host system before you were connected to the RAID controller module in the storage array, the host context agent software is not 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. 19 If 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. 20 If 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. 21 If the problem persists contact your Technical Support representative. 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.
