What if ESX conf file is corrupted...

one of my esx hosts in cluster is not showing network config in vc..

i have to do lun migration..in this cluster..which will require to migrate vm [datatsore] on this host..when m trying for validation...showing validation failed due to resource/memory crunch on host..which may invoke for ha/drs..but that is not active on this host[esx conf file is corrupted]

is there any way if we can do migration without rebooting vm..from this host/downtime?

Let me Explain more about this issue..
Host..which is showing nothing..in Configuration-Networking--Blank Screen Only:Looks like ESX Conf file has been corrupted.
Have total 12 Hosts[Esxi 4.1] under a cluster..but max VMs[60+] are running on this host only.[HA & DRS is Active on Cluster]
 
Now what I am looking for just to migrate data store[SVmotion] of some VMs running on this Host only.[As new lun ll be presented to remove existing luns-Lun Migration]
 
And Problem m facing here is..
 
Whenever am trying to migrate VM[Change Datastore] from this host..at very 1st steps[Right Click VM-Migrate]showing everything greyed except allowing for Change data store..which is my need here..
 
But when I go to next step(To Select Resource Pool)-In compatibility window showing :Host does not have sufficient memory resources to satisfy the reservation(Showing same for all VMs on this Host Only)
 
*Status For change Host Option: Greyed:showing Vmotion not enabled on Host.
 
 
Here I would seek you expert views that is there any way to  migrate VM(at least Data store change) on/from this host..without any downtime/outage..?
 
and also how can I do Storage vmotion for a VM having Physical RDM (Independent Persistent)..?..without any downtime/outage.
