First, I unfortunatly don't have access to read the provided link . I guess my level of access prohibit this page to be viewed...
Well, my understand of LUNs, is that all vendors, either in the FiberChannel world, and in the iSCSI world uses LUN WWN, which would be a unique identifer of a LUN. They also provide a Serial Number, as in regular SCSI. These refers to VDP pages 0x80 & 0x83. Please correct me if I'm wrong.
I can already the the Serial Number, but I'm wondering how the LUN WWN is handled on Netapp filers, or even if such concepts exists.
How to determine which LUN on the filer is mounted as which drive on the Windows host
On the filer, use the 'lun show' and 'igroup show' commands to identify LUNs served by the filer:
filer> lun show -v /vol/vol1/lun0 40m (41943040) Serial#: "OdCvFnbbKzih" Share: "none" Space Reserved: "no" Multiprotocol Type: "windows" Exports: shpc=1 /vol/vol1/lun1 100m (104857600) Serial#: "OdCvFnbbLMFZ" Share: "none" Space Reserved: "no" Multiprotocol Type: "windows" Exports: shpc=2 /vol/vol2/lun1 50m (52428800) Serial#: "OdCvFnbbH/Kr" Share: "none" Space Reserved: "no" Multiprotocol Type: "windows" Exports: shpc=0
filer> igroup show shpc (FCP) (ostype: windows2000): 10:00:00:00:c9:2b:fd:8e
On the Windows host use the 'lputilnt' facility to determine which filer a device is served by:
Go to "Lputilnt --> Adpater --> FCP bindings". Check the ID number and Target (WWN). This ID Number and target WWN for each filer (target) will be unique, so you can identify the filer serving the LUN.
To determine which LUN maps to which device:
"Computer management --> Storage --> Disk Management".
Right click the disk number and select "Properties".
Select Check Device Target ID number for the LUN.
This target number for the LUN will be the same as the ID number from lputilnt above, so you can identify which LUN on the filer maps to the device on the host.
