Symptoms

ESX 4.x host fails to boot

The boot process stops responding at the step:

store-logs

The VMkernel logs on the Alt-F12 console show a Check Condition for the boot storage device:

drivername: cmd 0x4100ba002000 has CHECK CONDITION byte 2 = 0x3
NMP: nmp_CompleteCommandForPath: Command 0x28 (0x410187ad4140) to NMP device "mpx.vmhba1:C0:T0:L0" failed on physical path "vmhba1:C0:T0:L0" H:0x3 D:0x0 P:0x0 Possible sense data: 0x0 0x0 0x0.
VMNIX: ALERT: VmkDev: 2540: Serial number 0 on disk sc0:0:0: pid=0x8047 cmd=0x3 [0:0:0:fc:0] doneFn=scsi_eh_done+0x0/0x54

Resolution

The startup fails due to SCSI commands failing to the local storage boot media. The specific failure reason can be determined from the console logging. For more information, see Understanding SCSI device/target NMP errors/conditions in ESX/ESXi 4.x and ESXi 5.0 (1030381).

For example, a SCSI command may fail with a Check Condition with Sense Key H:0x3, which translates to Medium Error. For a full list of SCSI Sense Keys, see http://www.t10.org/lists/2sensekey.htm:

drivername: cmd 0x4100ba002000 has CHECK CONDITION byte 2 = 0x3
VMNIX: ALERT: VmkDev: 2540: Serial number 0 on disk sc0:0:0: pid=0x8047 cmd=0x3 [0:0:0:fc:0] doneFn=scsi_eh_done+0x0/0x54

Note: The message may misreport a host-side error instead of sense data. For example, H:0x3 in conjunction with the Check Condition above actually indicates the same issue, Medium Error.

NMP: nmp_CompleteCommandForPath: Command 0x28 (0x410187ad4140) to NMP device "mpx.vmhba1:C0:T0:L0" failed on physical path "vmhba1:C0:T0:L0" H:0x3 D:0x0 P:0x0 Possible sense data: 0x0 0x0 0x0.

The boot disk, controller, and raidset should be reviewed for integrity and proper functionality. It is possible for an issue with any of these hardware components to affect the integrity of the ESX installation. If subsequent ESX startup attempts also fail, but no longer with the SCSI errors, consider re-installation of ESX.
