wwnhandler

Simple Python module to decode Fibre Channel WWN

Inspired by https://github.com/jbrt/devicewwn.git, just in a shorter form (only one file)

Supporting:

• EMC VMAX
• Hitachi
• Netapp E-Series

Create a WWN

At first you have to create your WWN object :

>>> from wwnhandler.wwn import WWN
>>> wwn1 = WWN("60000970000296800564533030324346")
>>> wwn1
<WWN(60:00:09:70:00:02:96:80:05:64:53:30:30:32:43:46)>
>>> wwn1.wwn
'60:00:09:70:00:02:96:80:05:64:53:30:30:32:43:46'
>>>
>>>
>>> wwn2 = WWN("60:06:0e:80:12:b1:6a:00:50:40:b1:6a:00:00:00:02")
>>> wwn2
<WWN(60:06:0e:80:12:b1:6a:00:50:40:b1:6a:00:00:00:02)>
>>> wwn2.wwn_nodots
'60060e8012b16a005040b16a00000002'

Useful properties

For EMC VMAX, Netapp E-Series and Hitachi there are more propertiers supported:

• oui : extract the OUI (Organization Unique Identifier) of the WWN
• vendor : extract the vendor
• serial : extract the serial number
• lunid : extract the 'LUN ID'

>>> wwn1.oui
'00:00:97'
>>> wwn1.vendor
'EMC'
>>> wwn1.serial
'000296800564'
>>> wwn1.lunid
'002CF'
>>>
>>> wwn2.vendor
'Hitachi'
wwn2.serial
>>> wwn2.serial
'45418'
>>> wwn2.lunid
'00:02'
