How to Detect New Fiber Channel (FC) LUNs in Solaris Without Rebooting

There will be a Knowledgebase document on this topic forthcoming.

----

1) Wait several minutes to see if the system detects the new LUNs by itself.

The devfsadmd daemon will be running in the background and constantly checking for the presence of new hardware, so often times the device will be found right away.

2) Issue "devfsadm -c disk" command.

3) Issue "cfgadm -al" or "cfgadm -o show_FCP_dev -al" command.

If the system is doing normal I/O then the luns should just show up without running any commands.  But if the system is not doing any I/O, you can use 'cfgadm -al' to tickle the wire and the system then picks up the new devices.
