Where do I find the wwn of a disk in Windows / HyperV? That’s the question.
There are a number of identifiers to find out which LUN is which disk, but the only undeniably unique number to find out which disk is which LUN is by using the globally unique wwn number of a LUN. The question is: “where can I find the wwn of a disk in HyperV?”
The LUN number, as assigned by the storage array can be found by using diskpart:
In the Unity the naa numbers (wwn) are listed in the “block” section, but not in the VMware section. If you view the LUNs from the host perspective, the naa numbers are visible, but in the list of LUNs would have been easier. You can list all details from LUNs and datastores on the CLI by using the uemcli commands:
uemcli -d 10.11.12.13 -u Local\admin -p [password] /stor/prov/luns/lun show -detail > unity.txt
uemcli -d 10.11.12.13 -u Local\admin -p [password] /stor/prov/vmware/vmfs show -detail >> unity.txt
Now simply open the unity.txt file and voila: there they are!
