I just attempted a generic search at Sun's corporate web page,
using keywork 'procom'.
I found this press release from 13-JUN-05 (13 months ago)
http://www.sun.com/smi/Press/sunflash/2005-06/sunflash.20050613.2.xml
That press release would suggest that you should contact
Sun's general techsupport staff for any issues,
because the Procom NAS technology is now an integral part of Sun.
So, begin here:

If your local Sun techsupport center isn't the correct place,
I would expect them to forward you to the appropriate department.
