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>

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.

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.

If there is a cable or network accessibility problem, see step 20, if not
step 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 is 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 have been installed.
17
Check all external cables and switches or hubs to make sure that no visible
damage exists and that they are securely connected.

Make sure the Host Context Agent software is installed and running.
