Hello,

I am new to windows,  this windows server is a VM and it is running on Vmware.  There are 4 RDMS attached to this VM.
How do I find the lun number from the OS?  These RDMs are coming from IBM storage.

how is the storage presented to the VM ISCSI, HBAS?

ISCSI look at the administrative tool ISCSI initiator there you will see the ID information that you can then use in the INM storage to identify the LUN.
If using HBAS, there should be an application installed through which you can see the presented resources that plan be used on the IBM storage to match to the allocated LUn.

HBAs,  Does it mean I we need a drive to detect the lun number?

You have to see how the VM is setup.  does the VMWARE host gets the LUN which are then assigned to the VM as disks. or is the VM directly interacts with the storage space.

What type of storage are you using FC meaning there is a fibre connection between the IBM storage and the VMWARE host, or is it an iscsi whereby on the windows 2008 VM, look at the administrative tool iscsi initiator.

You could look on the IBM storage, presumably the LUNS/Hosts will be defined such that you can see what luns are assigned to a specific host.

You would still need to identify the specific LUN to a specific resource which can only be done either on the host if that is where the storage resources terminated, or within the VM.
