It may be the case that the drive is faulty, I would just recommend checking these things before jumping to that conclusion, in case there is something else happening.

Hello,

How is the storage set up? Is this drive internal storage or external? Is it a member of a virtual disk, or is it being passed straight through to ESXi? What PERC is controlling the storage?

If you can acquire a PERC log, it may be helpful because it may yield some information on why the drive is getting an IO error. You can also run "esxcli hardware ipmi sel list > SEL.txt" to export the server's hardware log to see if the system is logging any hardware issues relating to storage.

Hi it is a virtual disk but on its own, its using the dell T410 built in Raid. Also its a local disk. the command you gave returns this : Unable to get IPMI System Event Log data : No records or incompatible version or read failed :

If you're talking about the on-board PERC, that should be the S300. That controller is only meant for use with Windows operating systems. You could look at going into BIOS and turning RAID mode off and setting it to AHCI. If it is set to RAID mode, that would activate the software PERC, and that may be part of the problem. 

As for the SEL, the only other way to get that would be either by accessing the iDRAC, or by booting to the live support image and launching OpenManage there. The S300 doesn't maintain a storage log, unfortunately.

I would recommend confirming that you are in AHCI mode, confirming the SEL is clear, and running the diagnostics on the server from the Lifecycle controller.
