Put an ESX host in maintenance mode.

Put an ESX host in maintenance mode.

Sometimes when I put ESX host in maintenance mode, some VMs do not move to another ESX host.
some of the VMs have CD/DVD drive1 connected to ISO Image on Local Disk.
Some don't have the CD/DVD connected, but still do not move

we have 6 hosts, and there are enough resources for vmotion

If I remember Hanccocka explained that to me..I cannot remember where I put the notes (:)

Thanks

Try to move one of the VM's manually and have a look on the error you get.

Make sure ALL your VMs which are ON, are disconnected from

1. floppy disks and floppy disk images
2. cdroms and cdrom ISO images

VMs which are OFF do not move, unless you Tick the Box to move them, but this should not affect Maintenance Mode, because ALL VMs have to be OFF.

if I understand , VM running on snapshot still can move to another ESX host.



the only thing was showing when I clicked on CD/DVD Drive 1,  was "connect to iso image on local disk"

was not sure how to disconnect it.

Correct, because it's the VM process that moves, NOT the virtual machine disk, it stays on the storage.

that will stop a vMotion, and VMs moving off a host.

CDROM either untick connected or it's easier just to select Client Device

@jskfan - yes, rt-click VM > Edit Settings and deselect ISO Image as your CD Device option & choose Client.

Yes, you need to edit the settings of the VM.
