Have you always had each of your fibercards zoned to two different storage controllers? When we had dual fibercards and we had a one-to-one mapping between our fibercards and the storage controllers. Then we used MPIO to put the 2 paths (instead of 4) together. I didn't even know doing it the way you are was even possible.

I would have expected an error message from the shell, but instead of that the shell ran the 'ls | sort' command and didn't realize the variable assignement. ... (1 Reply)

hptide
HPTIDE(4) BSD Kernel Interfaces Manual HPTIDE(4)
NAME
hptide -- Triones/Highpoint IDE disk controllers driver
SYNOPSIS
hptide* at pci? dev ? function ? flags 0x0000
DESCRIPTION
The hptide driver supports the Triones/Highpoint HPT366, HPT370, HPT370A, HPT372 and HPT374 IDE controllers, and provides the interface with
the hardware for the ata(4) driver.
The 0x0002 flag forces the hptide driver to disable DMA on chipsets for which DMA would normally be enabled. This can be used as a debugging
aid, or to work around problems where the IDE controller is wired up to the system incorrectly.
SEE ALSO
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)
BUGS
The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 30 or 33 MHz. This driver may not work
properly on overclocked systems.
