Hello Julius,

Thanks - but it doesn't seem to work.

I installed sg3_utils and ran #scsi-rescan

but that seemed to have done nothing for some reason.

Dumb question: did dmesg even bother to notice *something* was attached?

Cheers,

Boris.

Hi Boris, Just rescan the scsi host. #scsi-rescan #if you have sg3_utils package #lsscsi Or #echo "- - -" > /sys/class/scsi_host/host[n]/scan

Zep,

Thanks - nothing insulting about asking questions.

I did run this command as root as I would never run stuff like this as any other user (or, perhaps, I'd use sudo if so forced).

dmesg did not seem to detect the device addition, no.

Cheers,

Boris.

possibly dumb question, possibly unintentionally insulting your intelligence... you know that when he said "run # scsi-rescan" that meant 'type in "scsi-rescan" as the root user', right? and not '#scsi-rescan'? #anything will always appear to do nothing as the shell thinks you're typing in a comment. I only ask because I've never seen anyone respond with "I ran #command".

While I believe that this URL has technically correct advice, it's basically doing a subset of the commands in the scsi-rescan script in the sg3_utils package.

I wonder if you need to be running the vmware tools for the kernel to detect new devices?

Jonathan,

Thanks, good point. I do have VMware tools running on the VM, though.

was the controller you added the virtual disk to an IDE or scsi controller?

It should work fine. What esxi version you are using?

It was a SCSI controller.

@Boris: If you have CentOS 6 + ESXi5.5, it should normally work fine. Have you retry the operation by adding another vDisk? monitor /var/log/messages

Eero,

I know. It is EXSi 5.5

Thanks.

Boris.

It usually works very nice here, Have you added only the disk or by accident another scsi controller? This happens (you probably know) if you select another bus while creating the disc.

Rainer,

Thanks.

It looks like I just created another disk on the same controller as I intended - and once I rebooted the VM it worked just fine - I got my disks (/dev/sda through /dev/sdd) accessible and functional.

Cheers,

Boris.
