Hi There,
For anyone looking for an example code of how to do this using the DataONTAP PowerShell Toolkit
(download the PowerShell toolkit from here: http://support.netapp.com/NOW/download/tools/powershell_toolkit/)
See example code below which contains functions to convert the LUN Serial number from Hex/ASCII to display the VMware NAA number.
Happy Coding.
Cheers Matt
Example Output:
PS C:\Scripts\PowerShell\Projects\GetLunInfo> .\GetLunInfo.ps1 -HostName "netapp1"
netapp1,/vol/vol1/luna,True,True,HnWOlJWxYNtV,naa.60a98000486e574f6c4a5778594e7456,1024,832,vmware,True
netapp1,/vol/vol2/lunb,True,True,HnWOlJWxYczq,naa.60a98000486e574f6c4a577859637a71,1024,992,vmware,True
netapp1,/vol/vol3/lunc,True,True,HnWOlJPRSzsu,naa.60a98000486e574f6c4a5052537a7375,250,233,vmware,True
