Hi Vijaya,

Did you do a "Rescan Disks" in Disk Management?

Have you added a new SCSI card to your VM - and has the OS detected and installed this correctly?

update your VMTools, then go to device manager and 'rescan' - make sure that all drivers are installed and configured  - then reboot your VM

have a look at this how-to guide:

Hi,

Thanks for your responses..

We did rescan and installed latest vmware-tools in guest OS. Still volume is not detecting.

what about removing the rdm and reboot then re add back?

Hi,

Thanks for ur response..

The volume is showing in vSphere client but it is not came into guest OS. Is there any action have to do to come the volume into guest OS other than diskpart rescan?

Thanks,

Vijaya

i am experiencing this same issue.

any advice?

I've tried removing and readding the RDM

i've tried shutting down or restarting the VM

I cant get it to show in disk management when its added in physical mode.

If i add in virtual mode it shows up, however i dont really want to use virtual mode.

Can you please create a fresh VM and try adding the RDM to it?

Hi,

I recently faced the same problem. Had a VM running iSCSI initiator towards Dell MD3000i SAN. We decided to change this into RDM instead. When we presented the first RDM everything went smooth. But the second RDM did not show up in device manager. Did several rescans, reboots, re-add RDM etc.

Since the RDMs are presented as Dell MD3000i SCSI Disk i figured it might be some old info that disturbs, i noticed that Windows had activated MPIO for the disk that i got access too. So i did the following to get it up and running

From Add / Remove programs i removed the MPIO parts from Dell Storage Manager.

I opened up a command prompt and ran

set devmgr_show_nonpresent_devices=1

devmgmt.msc

From Device Manager select "Show hidden devices" and remove all Dell MD3000i SCSI devices

I hope this will help someone.
