We actually only had an issue with early (ie v1.0 ?) devices, which
wouldn't have any WWID. And we didn't have a 'wwid' sysfs attribute to
boot, making it hard for us to print out any wwid without the SCSI
translation layer.

However, this has been fixed now, so I'm game with dropping it.

Someone should tell HPe, though; apparently they are using it for
firmware download ...

Cheers,

Hannes
