Dell MD3200, MD3220 owner manual 230

To recover from an unresponsive storage array:

1Check the Tree View in the EMW to see if all storage arrays are unresponsive.

2If any storage arrays are unresponsive, check the storage management station network connection to make sure that it can reach the network.

3Ensure that the RAID controller modules are installed and that there is power to the storage array.

4If there a problem with the storage array, correct the problem.

5Perform one of these actions, depending on how your storage array is managed:

•Out-of-band managed storage array—Go to step 6.

•In-band managed storage array – Go to step 12.

6For an out-of-band managed storage array, ensure that the RAID controller modules are network accessible by using the ping command to make sure that the RAID controller module can be reached. Type one of these commands, and press Enter.

•ping <host-name>

•ping <RAID controller module-IP-address>

7If the verification is successful, see step 8, if not, see step 9.

8Remove the storage array with the Unresponsive status from the EMW, and select Add Storage Array to add the storage array again.

9If the storage array does not return to Optimal status, check the Ethernet cables to make sure that there is no visible damage and that they are securely connected.

10Make sure the appropriate network configuration tasks have been performed. For example, make sure that IP addresses have been assigned to each RAID controller module.

11If there is a cable or network accessibility problem, see step 20, if not step 12.
