Removing a VC domain from a VCEM domain group

Removing a VC domain from a VCEM domain group

Hello,

 

we have a single c7000 enclosure and want to remove VCEM as it has no further benefit.

 

When we remove the VC domain from the VCEM domain group using the button "Remove from VC domain group ..." will there be any effect on availability, reset on the Flexmodules or similar? Do we lose any assigned WWN/MAC addresses?

 

Any hint would be greatly appreciated.

Re: Removing a VC domain from a VCEM domain group

There will be no affect on availbility (I've done it a couple of times); it's a logical change that doesn't affect the running chassis/servers.

 

If you've used VCEM to generate your WWNs/MACs; those will come over with all active profiles.  But if you recreate or delete a profile it will start to use the range that you defined (an option during the removal process), you will no longer have access to the range you were using in VCEM.  So they'll just need to be rezoned, just something to be aware of.

Thanks a lot,

 

we were guessing that it is just a logical change on management level, but we`ve made some strange experiences in the past with VCM and VCEM, so we appreciate your confirmation.

 

Do you know what happens with the server profiles which are also managed by VCEM?

Do I have to unassign them before or after the VC domain removal?

Glad to help - any assigned (even if the blade is off) profile will stay with the server and migrate into VCM, retaining the WWN/MAC/SN.  I'm pretty sure if you have any unassigned profiles those go away.

Re: Removing a VC domain from a VCEM domain group

Hello,

We have a large VCEM 7.3 implementation controlling around 80 enclosures. We have a two enclosure VC Domain group that we need to change physical networking while keeping services alive in one of the two un-modified enclosures. My intention is to remove both enclosures from the domain group to do the work then add them back into the/a domain group in VCEM when complete.

Are there any known gotchas to accomplishing this process? I assume MAC's/WWN's will keep the same ranges specified in VCEM, and when your re-import the enclosures they will continue to use the same ranges?

Thanks for any insight.
