Does anybody know whether or not the SNIA HBA API library is available
for IRIX (and the Qlogic HBAs they OEM)?

I got a few web hits saying SGI was going to embrace it, but that was
dated 2001. If anybody has the latest version of IRIX, then perhaps
they are bundled with the O/S? (look for /etc/hba.conf to see if it
is at least configured).
