Brocade LUN Level Zoning

[Matt Burgess]

What is required for LUN Level zoning on a HP B-Series 4/8 or 4/16 switch?

Is it as simple as an "Advanced Zoning" license? It's my understanding that this should be included with the switch (when you buy it from HP) but a licenshow yields only:

Web License
Zoning License
Fabric License

Am I supposed to see "Advanced Zoning License"?

Hi,

I didn't think you could zone down to LUN-level on a Brocade switch. Just physical switch ports or WWNs (Port WWN or Node WWN, not the LUN WWID). The storage system should take care of which hosts can see which LUNs.

I don't think licensing is the problem.

Regards,

You can zone based on LUN. I just can't do it on this switch right now. I've seen this working on other 4/16 B-Series switches.

Matt:

Those are the licenses HP bundles with most of their Switch Packages. If LUN zoning is a switch feature, then it is definitely something that you probably need a license for.

On the other hand, I have never seen LUN zoning on a Brocade Switch before. Why you would even want to do LUN zoning at the switch level is kinda weird to me as well since... most newer storage arrays have LUN Masking.

Are you sure you seen it before? or are you maybe confusing it with another term? LUN zoning is not even listed in the Zoning Applet on a brocade Switch, only Mixed, WWN, Port and AL_PA.

Hi Steven,
Check this out:

5th from the bottom - "LUN Level Zoning"

The functionality here is that you can hide the EVA CCL from all hosts but the SMS.

It also allows you to implement SSP on legacy storage/libraries which do not support it.

Based on that link, I would be inclined to think that you would require the Secure Fabric OS license in order to make use of such a feature. (based on the way the idea is presented and worded).


"The functionality here is that you can hide the EVA CCL from all hosts but the SMS."

Not sure if this actually gains you anything, except maybe a more secure/controlled environment meaning somone can't just install Command View and take over control.

"It also allows you to implement SSP on legacy storage/libraries which do not support it."

Yes, this is the most obvious use, but considering that the most current legacy storage equipment (at least for HP) includes some form of Selective Storage Presentation... I am not sure why anyone would buy new 4G SAN Switches to utilize older and/or more prehistoric Storage equipment except in the case where you already "have" an old SAN and you want to keep it running, but your fibre hub or Switch died and you can't locate a suitable replacement via HP or a vendor (or ebay)

Bingo. That's what I'm looking for.

Also, Compaq RA4000 has no SSP.

Thanks for your responses but it hasn't really helped. I'm looking for someone who has actually used this feature.

Careful, please. The Storage Array Controller Device is used for more things than array management. If you block access to it, any SCSI-3 REPORT LUNS command will fail and your host might not discover any disks.
