Chapter 4 Troubleshooting Example 55
Check the Array Status
1. Telnet to the affected Sun StorEdgeg T3+ array (t3b2 in this example).
2. Issue the
fru stat
command to status the FRUs.
3. Issue the
port list
command to status the controllers.
4. Issue the
port listmap
command to determine the LUN mapping.
These command outputs indicate that both controllers are active, u2 owns all the
LUNs, and WWN
50020f23000003d5
corresponds to the WWN of the Master
Controller. This confirms that the problem is most likely not with the Sun StorEdge
T3+ arrays. Thus, there is probably an upstream path problem.
