Problems with "show device" command

I have a DS25 and when i run "show device" don't appear my 'dka.....' and 'dkb....' devices, but i know they must be there, where could be the error? what can i do to see them?

Ummm, is this a HP-UX question? What is a DS-25? Into which program are you using a "show devices" command? What is a dka and dkb? I have never heard of any of this... :confused:

Digital from what I googled.

A DS25 is a DEC box. He already posted this in another forum, can a moderator please close this?
