Scenario like this:
we have Vsphere 5.5 with multiple clusters, the cluster have multiple hosts, which is anyway common.
recently HP released a bug on few generation of Proliant server, http://kb.vmware.com/kb/2085618
, this bug is not allowing migration, vmotion with the affected hosts, and unfortunately our clusters are with these affected physical machines.
New we wanted to patch these physical hosts, with very minimal impact to VM.
So we thought we migrate VM to next host, and patch the server, and move back, but unfortunately cannot migrate the VMs to different host due to this bug. All the hosts in the cluster are same type of hardware, and all the hosts had same issue its not allowing migration.
So i need your advice to fix this issue with minimal impact.
