Enabling Virtual Fabrics on a switch already in use


Hi,

IHAC who wishes to enable Virtual Fabrics on an already active physical switch, create several logical switches and then migrate some of the already-connected ports to these new logical switches.

The customer was wondering whether zoned ports migrated between (for example) the default logical switch and a new logical switch on the same chassis would have their zones migrated at the same time? If not, is it necesary to delete the zone prior to migrating the ports?

Specifically, these are Brocade 5300 switches running FOS 6.3.1.

Thanks in advance

Re: Enabling Virtual Fabrics on a switch already in use

Hi,

First off enabling VF is disruptive to the fabric.

Once enabled all port belong default to the DS (ie Default Switch with FID128).

AFAIK the zoning database is switch to DS as well.

After that you can create a logical switch.

But each logical switch has, among other things its own zoning database.

So no port being moved between LSsen and or DS which are zoned don't migrate their zone as well.

And no its not necessary to delete a zone prior to moving it, but you'll be left with hanging members.

Ideally zoning is done with pwwn and not as DID/PID.

You need to notice the ISL's issues in VF environment.

You can use whether shared ISL's (that all virtual switches in the same chassis can use) that belongs to the base switch (it is not the default switch, and it can't be the default), or to dedicate own ISL to each virtual switch.

Also, in FICON environment you have additional limitation.
