Unfortunately, neither of these links explain how to match storage LUN to Windows device :( At the end the only safe possibility is to match LUN GUID but this is not displayed either by NetApp or by diskpart. NetApp shows only serial number that needs to be converted into GUID (and there is no official documentation how to do it) and I'm not sure whether GUID is stored somewhere on Windows. On Linux I use sg_inq to find it.

Another way is to figure out to which HBA disk is connected and match mapping LUN number. Again not something one would want to do manually.

Use diskpart.

Guys,

Trying to map LUNs presented to a Windows host back to the source Netapp Volume/Lun using something equivilent to the 'sanlun' command I can use on Unix systems.

I tried installing the Windows HUK (Host Utilities Kit) but burried in the release notes is a cute little statment that 'sanlun' isn't available on there.

Is there *any* tool which I can use from Windows to show me the Netapp volume and lun name from the Windows side of things?

Thanks, John _______________________________________________ Toasters mailing list Toasters@teaparty.net http://www.teaparty.net/mailman/listinfo/toasters

Windows command "wmic diskdrive get serialnumber,deviceid" lists serial number of each device. It just happens to display the S/N in the same ASCII format as "lun show -v" (7-mode) and "lun show -vserver <svm> - path <path>".

C:\Users\administrator.VGIBU>wmic diskdrive get serialnumber,deviceid DeviceID SerialNumber \.\PHYSICALDRIVE2 2Ff5c]ALEUCc \.\PHYSICALDRIVE1 2Ff5c]ALEUCe \.\PHYSICALDRIVE0 6000c29019552f108aa8b158a2eb040d

f35> lun show -v /vol/luntest/l1 10.0g (10742215680) (r/w, online, mapped) Serial#: 2Ff5c]ALEUCc Multiprotocol Type: windows_2008 Maps: winluntest=1 /vol/luntest/l2 10.0g (10742215680) (r/w, online, mapped) Serial#: 2Ff5c]ALEUCe Multiprotocol Type: windows_2008 Maps: winluntest=2

(Yes, I snipped some)

You won't get the NetApp volume/LUN/host name from tools native to a host/guest operating system, since that is not presented in standard SCSI code pages (a.k.a. VPD - Vital Product Data). NetApp management IP addresses are buried in proprietary pages, which is how SANLUN, VSC and other tools discover the NetApp controller or cluster hosting the LUN. From there the tools match S/N or NAA ID (which contains the S/N), like we just did above.

Share and enjoy!

I don't think you need our PS toolkit. It's not installed on the system I tested with. (Actually a VM, but the LUNs were attached via Windows iSCSI in the guest, so look the same either way.)

This is really useful. Now I just did this on my system and I get a bunch of disks without serial numbers shown. Is this because I need to install the Netapp PowerShell extensions first? I've been distracted by other issues all day today, and just now got a chance to try this out.

This is a shame, since it looks like it wouldn't be all that hard for the info to be pulled out and presented easily enough. Oh well... getting even this much info will be a big help.

John

I dunno... I forgot to include that I'm a Unix/Linux and Netapp storage guy, not a Windows admin at all, but I need to work on getting something working.

So would the PowerShell suggestion, SnapDrive or diskpart be the better tools?
