what situations can casue fabric lock

Dear All,

There are 5 Switch in my single fabric.

I have no idea when I actived the IVR zoneset, it showed the fabric lock.

What situations can cause the fabric lock?

Thank you,



Re: what situations can casue fabric lock

Fabric lock is a function of CFS.

A fabric lock is issued when when one switch in the fabric attempts to configure a CFS enabled application.

The fabric lock is released when the change is committed to the fabric.

You can learn more about it by reading this link -

Re: what situations can casue fabric lock

Thanks for your infomation.

In my configrations, I can not active IVR zoneset due to existing Qlogic SANBox switch.

And I found some information as following:

Be sure to add IVR virtual domains if the following conditions apply:

?When an IVR zone set is not active.

?If Cisco SN5428 or Qlogic SANBox switches exist in the VSAN.

So, I need to add some domains (domain id?) to IVR configurations, right?

Re: what situations can casue fabric lock

Yeah, that is a nice piece of the puzzle.

The issue is covered in this link -

But in essence, there is a name resolution problem.

If you define a virtual domain in your ivr config (howto is in the link) it will allow the two fabrics to become fully aware of each other.
