What hardware is ESXi running on? Rack server, Blade, etc.. What ISO did you use?
Excuse me for forgetting.
It's running on a HP ProLiant DL360 G7. I used "VMware-VMvisor-Installer-5.5.0-U3b.x86_64.iso" + last patch released "ESXi550-201609001.zip"
I didn't found a custom hp/vmware iso.
Else i did the same configuration(not the same serveur but the same iso+patch..) on another ESXi and it's perfect, i mean i get no issues.
The base image won't provide updated drivers on your server. You can also check compatibility VMware Compatibility Guide - I/O Device Search of your I/O devices with the current ESXi version you are running and get the latest verified drivers.
There are custom images provided by HP/VMware
You should also do firmware and driver upgrades
Hope this helps.
I already used the HP Service Pack Pro Liant before upgrading to the 5.5 so i think it's ok.
So, first i'm gonna try to use the Custom iso then check if my issues still be.
By the way, do you know if it's right to use last patch released with a custom iso or not ?
As long as vCenter is at the same or higher patch level. You typically want to keep everything consistent.
Thank you both of you, i didn't use the use but it seems interesting for me for automatic reservation, really thank you.
Finally i found the solution, as i have an HP3PAR Storage, i looked into the documentation and found that i need to set these values : queue-full-threshold 4 --queue-full-sample-size 32 for each devices (naa.xxxxxxx) (the command is : esxcli storage core device set --device devicename --queue-full-threshold 4 --queue-full-sample-size 32;"
I did it after using the HP Custom iso and it works normally, even faster than usual.
So it's ok now, thank you again for helping
