Troubleshooting: Your Storage Array Software 277
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 ensure that there is no visible damage and that they are
securely connected.
10
Ensure the appropriate network configuration tasks have been performed.
For example, ensure 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.
12
For an in-band managed storage array, ensure that the host is network
accessible by using the ping command to verify that the host can be
reached. Type one of these commands, and press <Enter>.
ping <host-name>
ping <RAID controller module-IP-address>
13
If the verification is successful, go to step 14. If the verification is not
successful, go to step 15.
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 ensure that no visible
damage exists and that they are securely connected.
18
Ensure 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, ensure 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.
