Newbie question, used brocade300 not plug-and-play...?



We bought a used brocade300 switch which we were assuming would be good-to-go out of the box.... Meaning, connect multiple fibres into it and everything just works. That is not the case though, I have a server (connected to the switch) that cannot see its LUN on a SAN (that's also connected to the switch). There seems to be a laundry list of zones created on the switch, could this be the problem/ should I just delete them all? What else could be the problem?

plug and play, is a magic word for a Windows Box, and no for SAN Switches.


you have to made a lot of config in the switch included zoning


if a config is present in the switch you have to delete it, for a simple reason the WWN not matching the WWN in you environments.

Access the switch via telnet or console(serial).

Log in with an account that has admin privilege.

If you don't care about the existing config on the switch/fabic run; cfgtransabort, then cfgdisable, then cfgclear, then cfgsave. Note; this will delete ALL zoning info on all switches in the fabric. 


See the Brocade Fabric Admin guide for your FOS version from the documentation tab of for information on zoning. Your switch should now be able to 'see' all connected F ports. It is good practice to use zoning to isolate groups of devices in zones: Zone_1: Server_1 --> StoPort_1; Zone_2: Server_2 --> StoPort_2; etc. Not doing this often allows a mishmash of multi-host or multi-initiator problems.
