Hi Mohammed ,

This issue could be caused by a possible issue in the RAID controller however we will need to investigate a little more.

Does the KVM console reported a PSOD (Purple screen) when the issue happened?

Did you notice any error message on the SEL log reporting storage alert?

What type of RAID controller is installed in the system?

Does the VMs lose connectivity in the system?

Please check in the CIMC>Sel log events for specific error messages from RAID controller. As I mentioned before, this could be a hardware issue affecting your server but more information will be collected.

PS: I recommend you to open a TAC case for further analysis in your server.

Hope this helps you!

Could you confirm that this "datastore 1" store is local disk on this server?

If so is it RAID configuration on some adapter?

If so what's the version of firmware running on that server?

Did you install cisco customized ESXi hypervisor or official VMware one?

I would check the health of

I would check the health of your storage, including the BBU, which greatly increases the performance for writes (or degrades if not healthy).

Also if consistency checks are kicking off, those put additional storage i/o on your raid controller (although normally default schedule for 3am on Sunday, every 7 days)

Would also check to see if you are having I/O spikes on both sets of guestVMs... Make sure you don't have internal backups/exports scheduled to run all at the same time, etc.

Also make sure you have up to date firmware and drivers to match your server and ESXi version.  See https://ucshcltool.cloudapps.cisco.com/public/#

In CIMC, what faults are

In CIMC, what faults are listed?

What is the status of the storage? 

- Status of the Virtual Drive

- Status of the Physical Drives

Per Dave's recommendation, open a case with Cisco TAC's server virtualization team for further analysis

Be sure to generate the tech support log bundle for the TAC engineer to review

Steps to export the logs on C-Series:

==================================== 

  1. Log into CIMC GUI
  2. Admin tab > Utilities
  3. Click "Generate Technical Support Data for Local Download"
