Setup: All vCenter/vSphere 5.0 products
VM01 - 1st ESXi host - currently added to the vCenter cluster
VM02 - 2nd ESXi host
New vCenter Server
iSCSI SAN
I'm a new Systems Admin, taking over for a recently quit (shape up or ship out situation - he shipped out) sysadmin. The vCenter server crashed, took the DB with it with no backup, and a VM Host running esxi 5.0 (VM01) went down. HA was setup, and so all virtual machines moved over to the other vmhost (VM02).
I have since spun up a new VM, installed vCenter Server 5.0 on a VM created on VM01 host. I added that host to the cluster on vCenter, and am now planning on adding the second host VM02 to this as well.
My questions are pretty simple I'm sure (I'm coming from a Hyper-V shop previously)
I see all the other VMs on the vCenter server here, underneath VM01, as Unknown - when I migrate the VM02 to this cluster, will those show up again, or will I have to setup the DRS, vMotion, and/or HA again?
HA was previously setup, but from my reading I see that the config (or some of it at least) is on the hosts themselves, can I import that configration back, or am I better off recreating that?
I'm doing this after-hours in a maintenance window, but the shop is technically 24/7. Should I expect any real downtime?
Thanks for any help/suggestions!
