What about the Windows C# Client for vSphere 6?
Let’s be honest, nobody has made the full swap to the vSphere Web Client yet. I’ve been pushing my colleagues and some customers to start using the Web Client, but it just isn’t up to par with the Windows Client. And I hate to admit but when a host or VM is down and I have to quickly walk through my vSphere environment to check for active storage paths, check VM and host settings, I still use the Windows Client for this. On the VMware Community there is a thread running that burns down the vSphere Web Client very badly, which in my opinion is not necessary. In other occassions VMware has already shown their listening and improvements to the Web Client are in the works. … [Continue Reading]
Cannot open the disk and could not open change tracking file
Lately I have seen a number of VMs going down after the backup has finished and snapshots get removed. At some point when cleaning the snapshot, the ESXi host decides something is wrong and then brings down the VM. After this we're unable to power on the VM and receive the error: "Cannot open the disk '/vmfs/volumes/xxxxxxxxxx/xxxxx.vmdk' or one of the snapshot disks it depends on". When you then check the event details of the VM, you'll see two messages: - "Cannot open the disk '/vmfs/volumes/xxxxxxxxxx/xxxxx.vmdk' or one of the snapshot disks it depends on". - "Could not open/create change tracking file". The fix to make the VM power on again is simple, however we still haven't been able to solve the root cause. VMware Support has suggested to bring down the number of LUNs connected to a single host and to upgrade to vSphere 5.5. … [Continue Reading]
VMware Auto Deploy with MSCS won’t work
Our environment is fully built using VMware Auto Deploy 5.1. All the clusters have their own ruleset and we're very content on how easily we update our hosts and deploy new hosts. However, recently we ran into a major issue with Microsoft Cluster Services inside VMs in combination with VMware Auto Deploy. In a scenario with an "old fashioned" MCSC cluster across boxes with Physical RDMs shared between the two cluster nodes (VMs), these RDMs seem to be stopping an Auto Deployed ESXi host from reconnecting to vCenter Server after a reboot. … [Continue Reading]

[Powershell] vCPU to Physical Core for XenApp VM
For our Citrix XenApp environment that runs on ESXi, we tend to keep a 1:1 ratio when it comes to physical cores and vCPUs. In other words, an ESXi host with 12 cores, will only be running 6 XenApp VMs with 2 cores or 3 XenApp VMs with 4 cores or any other combination, just as long as the vCPUs … [Read More...]

Time to switch your vCenter attributes to tags
VMware has been clear about it, you should switch to the vSphere Web Client and stop using the good old Windows vSphere Client. Being best kid in the class, I of course tell my customers to start using the vSphere Web Client when possible and I work with it myself most of the time. During an upgrade … [Read More...]
