6.If either port 1 or port 2 is offline, check the GBICs and cables.

7.If a Sun StorEdge T3+ array switch port is offline, log in to the Sun StorEdge T3+

array and look at the status of the controllers and the port list, as shown in CODE EXAMPLE 9-7.

8.If either controller is in a disabled state or if either port is offline, refer to the Sun StorEdge T3+ Installation and Configuration Guide for corrective action.

9.After the problem has been corrected, repeat Step 2.

Manually Clearing and Restoring the SAN Database

It is occasionally necessary to manually clear and restore the SAN database on the virtualization engines.

Caution –This procedure clears the SAN database and removes the configuration of the disk pools, multipath drives, zoning, and VLUNs. After you perform this procedure, you must restore the virtualization map to the virtualization engine pair using restorevemap(1M). This requires a valid copy of the

v1.san or v2.san files located in the /opt/WUNWsecfg/etc/vn.map directory.
