what happens to a configured datastore on a stand alone host when you move it into a farm?
Posted on 2011-10-28
The other day I asked a question about moving a stand alone ESXi host into our existing farm and hanncocka was kind enough to give me his advice. My question included the comments I made below;
"I am not sure I understand you step one or maybe I did not explain my question properly....We have a VCENTER with a DataCenter under it then a Cluster....under the cluster we have 4 hosts. I want to remove the oldest and slowest host and bring in a newer host that has the same version of ESXi 4.1 installed on it. After doing some research I would;
1. vmotion all the VMs off the older host
2. right click the cluster and remove the older host
3. right click the cluster again and select ADD host
4. enter the IP address and root name and password of the newer host we want to bring in
5. click next and hopfully that will bring in our newer host
6. vmotion some VMs over to the new host now that it is on the farm
Is it that simple? I know you know a lot more about this then I do"
I got a postive confirmation that I had the right idea, but I started thinking about it and our host that is not on the farm has been used for VMs before, although they are currrently powered off and the NIC card is not set to reconnect on startup. But, we used this host for quite a while and it's datastores were all pointing to a Buffalo NAS, that used an iSCSI connection. Our farm has its datastores on an EQUALLOCIC SAN. Will I need to delete the datastore configuration on the old ESXi stand lone host? How will the former stand alone host know which datastores it can use once I pull it into the farm? I was hoping to go throught he procedure this weekend but want to make sure I have all the steps right and complete all the configs first...thanks
