General best practices
Note: VMware recommends you follow these best practices to avoid a vSAN cluster failure.
  • Ensure that the driver and firmware version in use is compliant per the VMware Compatibility Guide for vSAN (VCG).
  • Ensure that all drives are Dell supported drives that are validated for vSAN, and that all Dell firmware updates are applied to these drives.

    For assistance with this verification process, contact Dell support.

  • This article also includes links to the VCG for all applicable controllers, including the PERC H730 and FD332-PERC controllers.
  • Review and implement the recommendations outlined in Best practices when using vSAN and non-vSAN disks with the same storage controller (2129050).

If best-practice recommendations are not followed, the vSAN cluster may fail with an unexpected disk failure declaration. One or more behaviors may manifest in the vSAN environment:

  • When vSAN is under load, you see that vSAN status as Unhealthy:
  • Latency-related alarms may be triggered.
  • In the ESXi host /var/log/vmkernel.log file, you see entries similar to:

    WARNING: lsi_mr3: fusionReset:2565: megaraid_sas: Hardware critical error, returning FAILED.
    WARNING: ScsiPath: 7133: Set retry timeout for failed TaskMgmt abort for CmdSN 0x0, status Failure, path vmhba0:C0:T0:L0
