During the past hours we upgraded our HPE blades from ESXi 6.0.0 U1 to 6.0.0 U2. During the process (using the vSphere Update Manager), the ESXi seems to be frozen on the step “About to install…”.
After 30 minutes we restarted all blades with this message thinking they were crashed/stuck… It’s been an error. The process wasn’t stuck, but only really really really slow. Perhaps it was specific to this version or to the HPE custom ISO, I don’t remember this problem before.
So if you’re see the same problem you can solve it by being patient… simply. The install will end after 35/40 minutes. I wrote this post because I noticed on other blogs than the process wasn’t working and you need to install manually the upgrade. In our case, it was wrong, just being patient.
