Issue/Introduction

The datastore is missing or inaccessible.

No partition table is found on the device when running either:
  esxcli storage core device partition list -d <device naa/t10 id> 
 partedutil getptbl /vmfs/devices/disks/<device naa/t10 id>

/var/log/vmkernel.log report commands failing against the device with SCSI code:   

H:0x0 D:0x2 P:0x0 Valid sense data: 0x4 0x44 0x0 

Or

H:0x8 D:0x0 P:0x0 

/var/log/vmkernel.log may report that the device is All Path Down (APD) state.

/var/log/vmkernel.log may report I/O errors against the device.

Environment

VMware vSphere ESXi 7.0.x
VMware vSphere ESXi 8.0.x

Cause

  • SCSI code H:0x0 D:0x2 P:0x0 Valid sense data: 0x4 0x44 0x0 indicates a hardware error reported on the device:
          D:0x2 => Storage Check Condition 
          Valid sense data: 0x4 0x44 0x0 => hardware error, internal target failure
  • H:0x8 => This status is returned when the HBA driver has aborted the I/O. It can also occur if the HBA does a reset of the target.
  • SCSI code H:0x1 indicates the ESXi host is lost connection to the LUN. The LUN is no longer visible to the host.

Resolution

  •  If the device is a local disk, please engage the hardware vendor to investigate further.
  •  If the device is an FC or iSCSI disk, please engage the storage vendor to investigate further.
