ESXi host own

One of our three ESXi hosts just went down, and we did NOT have HA enabled.

So now we have several VMs that say (disconnected). When I right click on a VM, I don't have the option to "Migrate".

Please advise the best way to move the effected VMs to the other ESXi hosts.

Environment Background:
3 DELL PowerEdge 2950 servers using NetApp FAS 2240 on NFS volumes. All volumes connected to 3 hosts.
LVL 8

Since you have it on shared storage you can remove the VMs from inventory then browse to the datastore where they're located from a different server and browse the VM folder, right click on the .vmx file and register back into vCenter/ESXi host on a different host than the one that went down.  For this reason it's nice to have Essentials Plus as a minimum

Be sure to note the data store names that are cached and the sub-folder because from time to time we end up cloning and/or renaming the VM and forgot that it does not change the underlying folder structure.

If you click on the orphaned VM it should state which datastore it was located in and which network port group it was using.  I would make sure you're using SMVI (and have the VSC installed) so that you can restore VMs in case they get corrupted.  If you have flexclone than downtime is 10 min. if you have storage vmotion, saved my skin a few times.

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

Not sure but how would you restore a VM if it got corrupted. We use Veeam but let's pretend we don't. We do have storage vmotion, vsc, and flex clone.

Also how do these things help reduce down time to 10 min? Doesn't feel like I'm using any of them.

Install the Netapp VSC (Virutal Storage Console) and configure Backup and Recovery that is available in it (on another note it also allows you to install NFS Plugin for VAAI which enables hardware acceleration).  

So once you have installed the VSC and backup properly it runs backups of the VMs and can quiesce VMs with vmware snapshots and then Netapp snapshots.

To restore just go to restore click on a VM and it will restore it for you.  If you want to restore a VM and have it usable just mount the backup which will mount it as a flexclone which is a read write volume and will mount it to your ESXi hosts.  Once this this done you register the VM and start using it immediately although it's still dependent on the snapshot/backup.  To put it back into the production datastore we use storage vmotion to migrate back.  Even if you don't have storage vmotion you can always cold migrate it but at least you can test your backups within 5 minutes..

Netapp has a lot of integration with VMware, make sure you enable deduplication that should save a good bit of storage for you.  Perhaps the consultantant that installed it can show you what you can use, I do this for most of my customers.

Remove the VM from the Inventory

Browse the datastore

Add the VM to the Inventory of another Host.

See Step 6 in this EE Article I wrote which shows you how to add to inventory

HOW TO: Clone or Copy a virtual machine in VMware vSphere Hypervisor ESX/ESXi 4.x or ESXi 5.0

first step will suggest you that browse to that data store and see if you can access it ,if yes
then login to the host on that vm is showing disconnect.

remove from inventory, and login to another host browse the vm on shared storage select vm configuration file and right click then register the vm.

and if you not able to datastore then first look on storage part first.


please share the output
