If you have installed to a newer version of ESXi on your Gen8 Micro Server and are now suffering from very low performance disk speed, try the following steps to downgrade to a former hpvsa-driver (scsi-hpvsa-5.5.0-88).
Just follow these simple steps:
- Download the driver and unpack the archive named hpvsa-5.5.0-88.zip
- Stop all VMs that are currently running on your machine.
- Enable SSH connections to your server in the GUI
- Copy „scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib“ to the /tmp directory (just use WinSCP for that) – In my case, this file is 699 KB.
- Start a Session to your server (using Putty)
- change directory to /tmp
1cd /tmp - Copy the vib file to /var/log/vmware
1cp scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib /var/log/vmware/ - Start the „Maintenance mode“
1esxcli system maintenanceMode set --enable true - Deinstall the running scsi-hpvsa driver
1esxcli software vib remove -n scsi-hpvsa -f - Install scsi-hpvsa-5.5.0-88
1esxcli software vib install -v file:scsi-hpvsa-5.5.0-88OEM.550.0.0.1331820.x86_64.vib --force --no-sig-check --maintenance-mode - Restart your ESXi, stop the maintenance mode, disable SSH connections and start VMs again
Hope that helps for you as well.
Hi,
Thanks for the info, I just did this process for a ESXi 5.5 update 2 March 15 on a ProLiant MicroServer Gen8 and it didn’t work unfortunately, I still get Lost access to volume 5654ffd3-a6404e75-57ae-a01d48c77d34 () due to connectivity issues. Recovery attempt is in progress and outcome will be reported shortly.

Successfully restored access to volume 5654ffd3-a6404e75-57ae-a01d48c77d34 () following connectivity issues.
every minute 🙁
This also did not work for me. Get this message when powering up my ESXI host.
Doesn’t work either for me. The command to remove the scsi drivers doesn’t do anything.
Worked perfectly on ESXi 6.5 with ProLiant ML350e G8 v2 and ProLiant MicroServer Gen8. Stupid HP drivers. Thanks man.
