->i have installed new SAN switch Brocade BR-300 24 port.
are you sure the Switch is Brocade 300 ???
1) Brocade 300 is not supported by FOS 8.x
2) in FOS 8.x is root by default disable
3) log as admin in command line and executed the command
"rootaccess --set all"
Brocade 300  is supported even by FOS 8.1.2
provide us output of command: userconfig --show -r root
--->>>Brocade 300  is supported even by FOS 8.1.2

before I replied I checked FOS 8.2.1a files and yes , it supports brcd300,5100 and 4 other older types
