Solaris 10 Fibre Channel Management

On Solaris 10 Fibre Channel Management is easy, cos the storage foundation kit is now integrated into the base OS, name is ”fcinfo“.

”fcinfo” utility is available to view fibre channel connectivity information.
”fcinfo” is especially useful, since it provides a tool with the base Operating System to view HBA and connectivity information, include HBAs from Emulex, JNI and Qlogic.

Warning!! You should do so only when the server fibre links are online or offline, and never do it continually while you are disrupting the fibre link. else you may never be able to bring up the fibre link till you reboot the server..

# uname -a

To check the details of a particular fibre especially during setup, use luxadm to match the fibre and its WWN.
