Fibre Channel failed not seeing redundant path

Question

Hi I recently started noticing the following issue in my messages file
Mar 17 16:23:00 pine genunix: [ID 408114 kern.info] /scsi_vhci/ssd@g290000602200
443c6257455730303138 (ssd12) online

It would be worth doing a physical check of the 69x0 VE engines and server side switches diagnostic LEDs.
You should also check StorADE and/or /var/adm/messages on the MSP for failure messages.
Cabling should be checked if these check out ok.
Check the output of cfgadm -al and make sure you have at least 2 fc-fabric controllers.
You can then run 'luxadm -e dump_map /dev/cfg/c<num>' to see if you can actually see the storage devices.
For a 69x0 you should see two active paths under luxadm display.
