One specific adapter in the system has perfor-
mance issues, while all other adapters in the sys-
tem are okay.
Errors similar to the following occur when the sys-
tem is booted up. In addition, the ALT+Q QLogic
BIOS banner is not shown; or FlashUTIL! is hang-

Troubleshooting Tip
The password is config.
Ensure that the adapter is plugged into a slot that
allows the adapter to use the full bandwidth avail-
able. Also check that the bus the adapter is on is
not shared by other high bandwidth PCI cards.
There are too many devices taking up extended
BIOS data area (EBDA) memory resources. To
free up enough resources to allow the adapters to
work properly, you can disable unused onboard
services such as Wake on LAN, PXE boot, and so
on.
QLogic recommends that you assign the target
numbers of the devices in the same order on multi-
ple adapters. For example, if controller A of an
array is assigned to target 0 on HBA0, you should
assign controller B of an array to target 0 on HBA1,
and then continue this same methodology for all
targets and adapters. Note that the driver and OS
must be reloaded for the changes to take effect.
# esxcfg-rescan vmhba<X>
You can find the vmhba value corresponding to
an adapter port by examining the
/var/log/vmkernel log, where the adapter is
assigned a vmhba<X> vector.
