Looking for guidance on installing a SLIC in a VNX2.  We have an FCoE card installed by default, and are adding a 4port FC card (to get SANcopy ability).  I have found good guides for replacing/upgrading cards, but I have not found good guidance on simply adding a SLIC to a system.  I know I added iSCSI slic's to a VNX5300 years ago, but I can't remember if I did it hot (with the system powered up) or if I shut it down to install, or if there was a reboot process for the heads that allowed me to do the installation.  The SolVe Desktop app doesn't give me a good indicator of what the process is if I'm just adding an additional SLIC.  Any suggestions?
