What make/model are the AIX box FC storage adapters? Have you investigated the BIOS configuration of those?

The on-board configuration of FC storage adapters is usually critical for good transfer performance (but you probably know that).

Have you tested the storage subsystem performance?

TRM(4)							   BSD Kernel Interfaces Manual 						    TRM(4)

NAME

     trm -- Tekram TRM-S1040 ASIC based PCI SCSI host adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device trm

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   trm_load="YES"

DESCRIPTION

     The trm driver supports PCI SCSI host adapters based on the Tekram TRM-S1040 SCSI ASIC.

HARDWARE

     SCSI controllers supported by the trm driver include:

     o	 Tekram DC-315 PCI Ultra SCSI adapter without BIOS and internal SCSI connector
     o	 Tekram DC-315U PCI Ultra SCSI adapter without BIOS
     o	 Tekram DC-395F PCI Ultra-Wide SCSI adapter with flash BIOS and 68-pin external SCSI connector
     o	 Tekram DC-395U PCI Ultra SCSI adapter with flash BIOS
     o	 Tekram DC-395UW PCI Ultra-Wide SCSI adapter with flash BIOS
     o	 Tekram DC-395U2W PCI Ultra2-Wide SCSI adapter with flash BIOS

     For the Tekram DC-310/U and DC-390F/U/UW/U2B/U2W/U3W PCI SCSI host adapters, use the sym(4) driver.
