Quick Post: vSphere 6.7 - Sporadic VM Resets by vSphere HA

We had a customer recently that upgraded from vSphere 6.5 to 6.7 and following the upgrade to 6.7, virtual machines were sporadically being reset by vSphere HA with the following message in the vCenter event log: Error message on <VM Name> on <Host Name> in <Cluster>: VMware ESX unrecoverable error: (vcpu-0) vmk: vcpu-0:Unable to decompress BPN(0x100018003) from frameIndex(0x3d4aa2) block 1 for VM(2103599) We got this logged with GSS quickly and after being sent on a bit of a goose chase with firmware and driver upgrades (the versions we were running we compatible, but not latest), GSS noted that 5 other cases has been logged over the past couple of days with this same issue.

vCenter Server 6.7 Appliance Backup Scheduler

This one will be a quick post, but I wanted to alert people to a new minor but useful feature that’s included in the vCenter 6.7 appliance, which is the ability to schedule backups natively within the appliance management interface. If you wanted to schedule an appliance based backup in 6.5, you would have to schedule a task to do so. Thankfully this was made easier by Brian Graf’s script, but now we have a way to build this in to the appliance configuration with no reliance on an external script.

vCenter 6.7 Embedded Linked Mode

[toc] Introduction Starting from VMworld US 2017, VMware announced their plans to support PSC replication and Enhanced Linked Mode with the vCenter Embedded deployment model, simplifying overall deployment and management requirements for a multi-vCenter environment. This feature is now included in the release of vSphere 6.7. In this post, I go over a little history for common deployment models, as well as what the new “vCenter Embedded Linked Mode” brings to the table.

vCenter 6.7 Cross SSO Domain Repointing

It’s back, finally! A new feature with vCenter 6.7 is the ability to repoint a vCenter Server to another Platform Services Controller node, that resides in an entirely different vSphere SSO domain. This functionality is huge for domain consolidation, and also domain splitting (which admittedly is a less required use case from what I’ve seen, but something that still can be a useful use case). Edit: As per a comment from Rupak, I believe this feature is only available on the vCenter Server Appliance and is not available for the Windows deployment of vCenter 6.
