230 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 Enter.
• ping <host-name>
• ping <RAID controller module-IP-address>
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 have been
performed. For example, make sure that IP addresses have been assigned to
each RAID controller module.
11
If there is a cable or network accessibility problem, see step 20, if not
step 12.
