Hi.
I'm using ESXi 5.0 (without vSphere) in a Dell PowerEdge server with one SAS Tape Unit and some troubles happened.
In this host, I have two controllers, one PERC6/i to disks and one SAS5/iR to the Tape Unit. I need to put this last controller (SAS5/iR) in Pass-Through mode and then I configure this device directly to a VM. And here is the problem.
I configured the SAS5/iR to DirectPath I/O in Host/Configuration/Advanced Settings and reboot the host. After the boot, the controller configured in Pass-Through mode was the PERC6/i, not SAS5/iR.
Now, when I try to remove the PERC6/i of the Pass-Through mode, the configuration does not work. The host reboot with the PERC6/i in pass-through mode.
I read the /etc/vmware/esx.conf to try find some trouble, but everything is OK. When I remove the configuration by the vSphere Client, the line /device/..../owner="passthru" is removed, but after the reboot, it comes back.
These are the devices.
Anybody knows this problem??
Thanks very Much.
Hi Lauan
Welcome to the communites
Could you please let us know BIOS version .
As you have already done setting on config file ,it seems eother BIOS problem , after restart dont forget to corss cehck the config file .
Hi emma.
I can't reboot the server now, but it's the production server.
When I can reboot, I going to see the BIOS version and if it's up to date.
Thank's!!
If your server boots from the perc 6/i, the direct path i/o connection stops you from being able to save configuration changes.
I had this issue with a usb hub and usb memory stick i was booting from.
There is a workaround but i found it easier just to reload esxi.
