It seems it's one device: mpx.vmhba2:C0:T5:L0

How is this device configured? Does it have all paths that it should have?

Checking the config on the cli can be done with: esxcli storage core device list -d mpx.vmhba2:C0:T5:L0

Please let us know.

Hi bryan,

Thank you for your reply.
When i checked from cli with the command you provided, i got following result. It seems like mpx.vmhba2:C0:T5:L0 is a CD-ROM?

Any suggestion?

[bryanvaneeden]

Are you by any chance using that physical CD-ROM for a virtual machine at the moment? Or have you done this in the past?

You can get the VM's with connected CDROMs with the following PowerCLI command:

Get-VM | Get-CDDrive | ?{$_.Connectionstate.Connected -eq "true"} | Select Parent, IsoPath

Hi bryan,

It don't think we are using CD-ROM in any ,currently.

Also this command didn't work:
Get-VM | Get-CDDrive | ?{$_.Connectionstate.Connected -eq "true"} | Select Parent, IsoPath

[bryanvaneeden]

It didn't? What error are you receiving on that?

If I execute it I receive the following output;

PS C:\Users\Bryan> Get-VM | Get-CDDrive | ?{$_.Connectionstate.Connected -eq "true"} | Select Parent, IsoPath

Parent         IsoPath

------         -------

VM-1     [] /usr/lib/vmware/isoimages/linux.iso

And in regards to the CD-ROM, I would advise you to check with the above script just to be sure. If it's not beeing used I will have to look around what it could possibly be.
