3 If you have an in-band storage array, use the following procedure. Click
Refresh after each step to check the results:
Ensure that the host context agent software is installed and running. If
a
the host is started before it is connected to the controllers in the
storage array, the host context agent software is not able to find the
controllers. If so, ensure that the connections are tight, and restart the
host context agent software.
Ensure that the network can access the host by using the ping
b
command in the following syntax:
ping <host-name-or-IP-address-of-the-host>.
If the network can access the host, continue to step c. If the network
cannot access the host, go to step d.
Remove the host with the unresponsive status from the MDSM, and
c
add that host again.
If the host returns to optimal status, you have completed this procedure.
Ensure that the power to the host is turned on and that the host
d
is operational.
If applicable, ensure that the host bus adapters are installed in the
e
host.
Examine all external cables and switches or hubs to ensure that you
f
cannot see any damage and that they are tightly connected.
If you have recently replaced or added the controller, restart the host
g
context agent software so that the new controller is found.
If a problem exists, make the appropriate modifications to the host.
4 If you have an out-of-band storage array, use the following procedure. Click
Refresh after each step to ensure the results:
Ensure that the network can access the controllers by using the ping
a
command. Use the following syntax:
ping <controller-IP-address>
If the network can access the controllers, continue to step b. If the
network cannot access the controllers, go to step c.
