How to delete device special files for disks that don't exists

I'm sure this has been asked before but I can't find anything in the forums or in the Hardware Management Guide.

I have device special files for disks that don't exist. How do I delete them? I think it would be with dsfmgr but nothing I try works (dsfmgr -D dsk511*).

Here's what I see:
sobds2:/> hwmgr -v d

If the disk is not showed in hwmgr v d or hwmgr show scsi, then you can safely remove the device special files using the rm command.

Then run dsfmgr -v
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Ivan,

Didn't try 'hwmgr show scsi', that listed a disk with Device File '(null)'. Deleted that via 'hwmgr delete component -id' and those special device names were gone.

Thanks,
Vic
