Datastores missing after power failure

Hi,

​I have a HP Micro server at home. There are 4 4TB disk in it.  I had a power failure and  then the ESXI 5.5 wouldn't boot anymore. So I downloaded the image again and did an upgrade and now it boots again but my datastores are gone. I see in the Var/log/vmkernel.log that there is still something there because a vm that was running gives an error. I see the VM name in the error.

2020-06-12T21:05:19.876Z cpu0:36039)etherswitch: L2Sec_EnforcePortCompliance:155: client [servername] requested promiscuous mode on port 0x2000006, disallowed by vswitch policy

​I also have this error:

​2020-06-12T21:07:50.617Z cpu1:33325)NMP: nmp_ThrottleLogForDevice:2321: Cmd 0x85 (0x412e80885300, 34385) to dev "naa.600508b1001c27ae1dacdc4789853a81" on path "vmhba1:C0:T0:L0" Failed: H:0x0 D:0x2 P:0x0 Valid sense data: 0x5 0x20 0x0. Act:NONE

and

​Any advice ?

​Greetings

Welcome to the Community,

does the command esxcli storage vmfs snapshot list return any output?

see "Command Line" section at https://kb.vmware.com/s/article/1011387

Ok, so let's see what may cause this.

To start with, please provide some details about your setup:

  • which exact version/build of ESXi do you use
  • are the disks configured in a RAID set
  • which RAID controller do you use
  • what's the output of ls -lisa /dev/disks
  • in case the missing datastore is on a separate LUN (not the installation LUN), what's the output for the command in step 1 at https://kb.vmware.com/s/article/2046610?lang=en_us

After going into the Raid Setup and restarting one more time. (did multiple restarts already)

I am seeing the datastore again. I don't know why. Because I didn't applied anything in the raid setup.

(the outputs are from before the startup)

Thank for your effort André.

Greetings

Tom
