Decommission a vCMP guest and reallocate its cores to remaining guests
We're planning to delete a vCMP guest that is not in use anymore, to reallocate its cores to other remaining guests. (Viprion C2400 with 3 x B2150)
I was wondering if any of you have already tried deleting a vCMP guest. Does this require changing it to Configured state before we can delete it? Is there also a need to delete its Virtual Disk?

- you can delete a vcmp guest in any state (also running)
- the virtual disk won't be deleted, it will be de-associated. You can delete it in the vCMP / Virtual Disk List menu if you wish.

Fore removeving Guest you can do it without restriction. Once you remove Guest you have to remove Virtual Disk:
- On the Main tab, click vCMP > Virtual Disk List.
- Locate the Virtual Disk List area of the screen.
- In the Name column, locate the name of the virtual disk that you want to delete.
- To the left of the virtual disk name, select the check box.
- Click Delete. The system prompts you to confirm the delete action.
- Click Delete.
however, when you will reallocate its cores to other remaining guests, you must pay attention:
If you have a guest that's actively processing application traffic and you decide that it needs additional CPU cores than its original core allocation, you can increase the number of cores per slot for the guest. To do this, you'll need to temporarily disable the guest while you add cores, and then re-deploy the guest.

@youssef rhazi thank you! on the part of reallocating cores to remaining guests, if the guests are configured for HA, will the HA pairs' status turn to Disconnected or Changes Pending after the core reallocation? Or will they still remain In Sync after?
Sorry, can't simulate this in lab as we don't have a spare device with vCMP license. But I'm assuming that they should still be In Sync after core reallocation. Would like to know if anyone has had experience with this. 😊
