Although I was not the one with the problem originally, I had the same issue and discovered a problem with networking settings. Specifically, it was an IP conflict with the vmotion IP address and another host on the network. As soon as I fixed it, it worked immediately.
This looks very helpful. What if you have VMs with multiple disks, and some of those disks are located on other datastores? Will it still register properly? Thanks -N

Well, I have not had the same luck with setting our citrix servers to a single vCPU, even when providing 4GB to each VM. User experience is severly impacted, as well as overall %cpu usage within the VM. I do not want to set CPU affinity so we can utilize Vmotion. One suggestion that was made was to place all multi-proc VMs on the same Host(s). This way, the cpu scheduler didn't have to 'work' as hard providing cpu 'slices' to multi vs dual proc systems. It did help a little. Even Citrix' best practices guide says that you throw more memory at VMs, not virtual CPUs; it just didn't help in my case. Unfortunately, we use many custom apps that may not work well under single CPU conditions. I'd guess there are over 30 apps installed per machine. FYI - we are running 2 dualcore 3.06 ghz Xeons with 16GB each. Three Citrix VMs per host at this point. Any other suggestions would be welcome Thanks
If I perform a fresh installation, will I have to manually present the LUNS again, or will just an HBA scan do the trick? I hard-zoned the switchports. -N

I am getting ready to upgrade our 3.0.1 farm to 3.0.2. I have all the needed components, have all my steps documented, etc. What I would like to know is: Is it recommended to disconnect the HBAs from the switches before performing the upgrade? Are there any remote datastore components that need to be 'touched' by the upgrade, other than locally-based config files? All VMs will be migrated to other hosts before the upgrade, obviously. Virtual Center will be running at 2.0.2 as well... Also, is it recommended to use the CD vs 'esxupdate' from the extracted tarball? I'm comfortable with the cmd-line having patched many hosts manually, installing HP Insight Agents, etc. I know there are probably threads that touch on a few of these points, but any information you can provide would be greatly appreciated. Thanks in advance for your input. -Nate

yeah - I've tried that, too. I was able to connect to the cluster through a 3rd server, and all nodes looked good initially. When I began testing (i.e. drain stops, etc), the node(s) would not reconverge when bringing it back to the original state. FWIW, I'd just like to get an idea of other's configurations: 1) Single NIC 2) Multiple NIC 3) Unicast 4) Multicast Thanks

First of all, let me state that I despise windows NLB. Given that - I'd like to know how I can get it working when each guest node is 'living' on separate ESX hosts. I have tried unicast with multiple NICs, multicast, etc. I cannot get it working. Once I enable it, one host cannot reach the other. I have read a few articles on configuring it, but they are of no help. These refer mainly to disabling 'notify switch' settings. Anyone ever configured this before on VI3? Thanks
Thank you both for your help. Both of these are very helpful.
Thanks everyone. Your input has been extremely helpful for a N00b like me. -N

We all know that VMotion and DRS won't work when virtual machines have devices mapped to host or remote media (/dev/cdrom, client device, etc). In the interest of optimizing cluster resources, ensure DRS and Vmotion will work for any VM, I'd like to run a script periodically to disconnect or remove all mappings on all VMs. Has anyone built a script to do this? If so, I'd GREATLY appreciate if you could share. I know this would be a 'use at your own risk' script... Thanks in advance -N

This should be a simple question for all y'all experts (and regular-types) out there. I added a new LUN / VMFS datastore to my 4-node cluster and would like to move a few of my existing VMs to that new datastore. What is the easiest method? I know you can't just copy the VM files over and re-regstier... Thanks Nathan
