ESX 3.5 Problems.. I/O Error: dev 08:02, sector 8716432. Please Help!

[Stisse-SYSteam]

Hi,

I get this error in the consol all the time and iam not able to login to the server, not on console or Virtual Center.

I/O Error: dev 08:02, sector 8716432

...

....

.....

In the emerency consol I have this Error: VSCSIFs: 235: Failed reset of virtual target

The VMs on the host is running and I can connect to them by RDP.

Have run all diagnostics test on the server but no error found (IBM x3650, 6x 146GB internal disks Raid 1+0, 2x CPU Quad core, 9GB ram).

reinstalled the server, but still got the same error?

IBM could not find any errors on the hardware, but iam not sure of them.. Isn't this pointing to an disk error or scsi error?

Hello,

Sounds like a bad block/controller somewhere within the host. I would contact your hardware support agent. But I would also take the machine offline do the following:

Ensure Firmware is up to date

Ensure BIOS is setup properly for ESX

Run vendor diagnostics for 24+ hours

Run memtest86 for 24+hours

These will help pinpoint subtle problems.

Best regards,
