I have one New San Switch Brocade 300 Series and I want using ISL to connect it to Existing San Switch 5100 series with online installation ( Not down time ) , how to step by step configuration ISL for both switch ? Thx

Simplest way is:
Rack you New switch, after ensuring it works and setting an IP address, power it off.
Then connect a fibre cable between your new and existing switch.
Power on the new switch.
You are done !

ISL is very simple.
assign a Different Domain ID to the second Switch, ( each switch in the fabric must have a unique Domain ID ) and connect both Switch with FC Cable from One Port Switch-1 to another Switch-2
Use the command "switchshow" to verify the Domain ID.
If necessary upgrade the FOS in the NEW 300

thx for your support , but no problem with Domian ID ? ? .., because i get info that if " Domain id " on both switch is same then will replace configuration of the existing san switch ( configuration of the existing san switch will be lose ) when both san swtitch will be ISL configure ....

with the method I suggest, the Switch will negotiate a domain ID and will NOT conflict with the existing switch.
But you do also have the choice of setting a Domain ID manuall as ABBA-systems suggest,
while this is an extra configuration step, it is recommended practice.
If you zone your fabric using WWPN's then the Domain ID really is nothing you need to worry about and letting the switches sort it out is the simplest method.

you have to disable the new SW,
switchdisable , cfgshow, cfgdisable , cfgclear, configure and set the fabric.ops parametres similerly as the existing one except the DOMAIN ID(it should be unique 1-239, by default it is 1 in each new SW), cfgsave.
again disable the SW by switchdisable
connect the ISLs, then enable the SW by switch enable, The ISL ports will show you E ports. Confirm it with islshow.Also if you have trunking licenses on both the SWs, trunks will be formed if the trunking criteria meet, common speed, same portgroup.Always prefer Trunking to ISL

Even if it is a new sw, I do not understand What's wrong by putting and trying these commands.They will come to know a lot.I understand these should be tried with the used SWs, but what is harm to clear the configuration. The people, who are putting the questions here are not experienced like you.
