Troubleshooting: Your Storage Array Software 243
12
For an in-band managed storage array, make sure 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 successful, see step 14, if not, 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 are 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 may not be able to locate the new AMW software needed to
manage the storage array with the new version of the firmware.

If the problem persists contact your Technical Support representative.
