Thanks for your reply, Mike I simulated HBA failure by disabling the switch port. Before doing so, I started a batch file copy process. During the failover, the VM seemed to be in 'sleep' state where there was no activity and as soon as the second path became available, the copy process resumed. So it shows that its working. But I am still unclear if there will be any data loss or crashes etc.

Hello all, This one is more of a query than a problem! I am trying to understand the 'behind the scene' stuff for a scenario when one of the two HBAs in the host fails and the path fails over to the second one. What happens to the ongoing VM activity whilst the path is failing over? For eg. if I am copying something from a physical/virtual machine to the VM on the SAN in question, or what happens to the SQL transactions etc.? Any help to enlighten would be highly appreciated!! Cheers!
Hi Stuarty1874, The solution is to restart the hpsmhd and snmpd services. This will also fix the connection timeout errors if you are getting any. Let me know how it goes. Cheers!

Hi there, We have kind of similar situation: we were having an ESX 3.5 host on a HP ProLiant DL580 G5. We swapped the disks to a new HP DL580G5. Since the change, I am not able to make the VMKernel portgroup work. Whatever NIC I attach to the vswitch that has VMKernel portgroup, its link does not come up or if it comes up, goes down and then comes back up. Its flapping! The physical switch port is 100MB Full and I have configured the NIC to the same speed/duplex setting. But it still shows as down in VI Client and service console. The NICs are Intel PRO/1000 PT Low Profile Quad Port PCIe Gigabit Ethernet Controller. No matter which port I use on the physical NIC or which physical NIC I use, it doesn't seem to like it. Also I tried setting speed/duplex setting using esxcfg-nics command from SC, but it does not seem to taking any effect. The Service Console and Virtual Machine vswitch/portgroup works fine..its just the VMkernel.. Any help would be greatly appreciated!! Many thanks.

Hi, If you are getting this message during POST, then you can press ctrlE or altE and then go into Emulex BIOS. Once inside, you can select the HBA in question, select the option to Enable the BIOS. Once done, you can plug the FC cable in and it should be fine. Let me know how it goes. Cheers.

Hi, Because you cannot have ESX hosts registered (or added) to more than one VC Server at a time, once you have installed VC 2.5 you will need to remove the hosts from VC 2.0. In order to remove the hosts from a VC server, you will have to put them in the 'Maintenance Mode' and the host won't go in a maintenance mode unless you have shut down the VMs (or moved the VMs). AFA running VC in a VM is concerned, support should not be a problem (that's what we were told in the VMware course! me too actually I faced this problem myself) And you cannot VMotion a VM between hosts having different types of CPU. So its kind of strong dependency loop!! HTH

Hi, I have just done VC upgrade from 2.0.1 to 2.5. And there are 3 different ESX hosts in the cluster : 3.0.1, 3.0.2 and 3.5. I have got HA and DRS enabled on the Cluster. And I AM ABLE to manually migrate (hot and cold) VMs between the hosts. But I should admit that there were serious issues with our 3.0.2 host after VC 2.5 upgrade. It was completely 'messed up' in that service console was not pingable, it could not ping other hosts, the VC Agent service was crashing and the host could not even list the rpm pacakage details. Had to rebuilt the host!!! Not sure if there's a problem with VC2.5 and 3.0.2!!!

Hello chaps, I was able to VMotion this VM and it did not give any errors. The reason I am posting back the results this late is I wanted to make sure that the VM (having VC) keeps on running properly and it does. So looks like VMotion'ing VM with snapshots work! But there may be cases where it may not work (like in PeWe1201's case) and so I would use snapshots ONLY when required and then delete them.
Hi, I haven't gone ahead with the migration because this VM is our VirtualCentre. But I will give it a go as its just a test environment. Will post back my results. Cheers for your help, chaps...

Hi All, I am trying to migrate one of my VM (having a few snapshots). Both the source and destination ESX hosts are similar hardware type and attached to the same FC SAN. When I try to VMotion this VM and select the destination host in 'Migrate VM Wizard' it gives a warning in 'Compatibility' pane saying 'Reverting to snapshot would generate error (warnings) on the destination host'. I tried VMotion'ing another VM which does not have any snapshot taken and it didn't give this warning. I also tried to go for cold-migration for the problem VM, but same warning !!! Does anyone know what does this mean? And what's the way to make it work? Cheers, Kinnar
