So the day finally came: time to upgrade one of our VxRail clusters from 7 to 8. On paper, it looked simple. Run the pre-check, hit upgrade, sip coffee, and bask in the glory of being done before lunch.
Spoiler: that didn’t happen.
(And yes, we’re still on good ol’ vSphere. Don’t laugh. Hopefully one day soon, we’ll have a shiny VCF setup. I’m already daydreaming about VCF 9.1, where VMware promises the VxRail upgrade path will finally feel less like a haunted house tour.)
The Plot Twist: vCenter Said “Nope”
Everything looked good until the vCenter upgrade step:
- GUI Error: Failed to upgrade VMware vCenter Server Appliance
- CMD Error: Could not found system credential with name psc_root_
Because of course, nothing screams “fun” like errors that sound like they were written by a cryptic fortune cookie.
Meanwhile, In Appliance Land…
Even though the upgrade bombed, I poked around on the new vCenter appliance anyway. Powered it on, ran through the wizard, got to the pre-check, and was greeted by another beautiful error.

A quick search later, I stumbled across Broadcom KB 312122:
vCenter Server preupgrade check error explained
Followed their fix, went back to VxRail Manager, resumed the upgrade, and… miracle of miracles, it worked.
My “Unofficial” VxRail 7 → 8 Upgrade Checklist
- History lesson – If someone else managed your environment before you, get the backstory. Ghost PSCs are real.
- Run your pre-checks – Don’t just trust the green check marks; actually read the details.
- VXverify – This one is critical. Run it. Love it. Respect it. Make sure to get the newest version – https://www.dell.com/support/kbdoc/en-us/000021527/vxrail-how-to-run-vxverify#downloadlatest
- Passwords – Double-check your account creds. Nothing like a forgotten password to turn an upgrade into a therapy session.
Bonus Round
- Reboots matter – If your hosts haven’t been rebooted in forever, give them some love. Same for the VxRail Manager appliance.
- Dell ProSupport Plus – If you’ve got it and don’t feel 100% confident, open a ticket. No shame in phone-a-friend.
- Local updates > Internet updates – Trust me, you’ll sleep better.
Final Thoughts
Upgrading VxRail should be “push button, drink coffee.”
But in reality? It’s more like “push button, panic, Google error, find obscure KB, try again, finally succeed, then finally drink coffee.”
And hey… maybe once VCF 9.1 lands, this process won’t feel like an escape room with bad lighting. One can dream.
