Troubleshooting: Your Storage Array Software

To recover from an unresponsive storage array:

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

unresponsive.

2 If any storage arrays are unresponsive, check the storage management

station network connection to make sure that it can reach the network.

3 Ensure that the RAID controller modules are installed and that there is

power to the storage array.

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

6 For 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 .
• ping
• ping

7 If the verification is successful, see step 8, if not, see step 9.
8 Remove the storage array with the Unresponsive status from the EMW,

and select

Add Storage Array to add the storage array again.

9 If 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.

10 Make sure the appropriate network configuration tasks are performed. For

example, make sure that IP addresses are assigned to each RAID controller

module.

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

step 12.
