Problems getting target mode to work with isp driver

[Penta Upa]

Hi Matthew,

I changed the setup to use a solaris initiator and it worked fine then. The
solaris m/c is a different box with a 2340 card. I guess the linux box is
the culprit. I assume that it it isn't an issue with linux os (RHEL 5.2) as
it had been used as an initiator many times before and no changes were made
to that system.

Could it be that after all its a HBA issue or a cabling issue ? I'll try to
move the HBA from the linux box to the solaris box and try to confirm that.

Thanks,
Penta
