I updated a vCenter server to 7.0.x when logging into the newly updated vCenter one host in the cluster state the following alert.<\/p>\n
Error: “vSphere HA agent cannot be correctly installed or configured” (2056299) (vmware.com)<\/a><\/p>\n The KB didn’t sound promising. Checking the hosts event logs. a bunch of errors about \/tmp ramdisk being full…<\/p>\n The ramdisk ‘tmp’ is full – VMware ESXi on HPE ProLiant – Davoud Teimouri – Virtualization and Data Center<\/a><\/p>\n For real? Wow, not gettin’ lucky last couple weeks. Sure enough exact same issue, cleared \/tmp temporality, and downloaded the patch. When I vMotion the VMs from this host onto another host the VMs themselves showed alerts.<\/p>\n Virtual machine failed to become vSphere HA Protected and HA may not attempt to restart it after a failure.<\/a><\/p>\n I kept chugging alone in hopes I’d resolve each VM later. However as soon as I placed the issued host into maintenance mode, the alerts from all VMs disappeared. Applied to patch exactly as the HPE KB stated<\/a> for the ESXi version it was on.<\/p>\n With luck on my side, the host came up clean, and came out of maintenance mode without an issue, and all error and alerts were resolved. Woooo!<\/p>\n Hope this helps anyone doing a vCenter upgrade to 7.x<\/p>\n","protected":false},"excerpt":{"rendered":" I updated a vCenter server to 7.0.x when logging into the newly updated vCenter one host in the cluster state the following alert.
