TABLE E-8

Advanced Adapter Properties Screen Field Descriptions

Field

Description

IRQ

The Interrupt Request Line used by the adapter. The system BIOS
assigns this value.

NVM

Indicates whether an adapter has nonvolatile memory (NVM)
associated with it. An adapter’s configuration is stored in its
associated NVM.

IO Port Address

The I/O Port Address used to communicate with the adapter. The
system BIOS assigns this number.

Chip Revision ID

The Revision ID of this adapter.

Spinup Delay

The number of seconds to wait between spinups of devices attached
to this adapter. Staggered spinups balance the total electrical current
load on the system during boot. The default value is 2 seconds, with
choices between 1 and 10 seconds.

CHS Mapping

Defines how the Cylinder Head Sector values are mapped onto a
disk without pre-existing partition information. CHS Mapping
allows two settings:
• SCSI Plug and Play Mapping (default) automatically determines

the most efficient and compatible mapping.

• Alternate CHS Mapping utilizes an alternate, possibly less

efficient, mapping that may be required if a device is moved
between adapters from different vendors.

Note:

Neither of these options has any effect after a disk has been

partitioned using the FDISK command. To change the CHS Mapping
on a partitioned disk, use the FDISK command to delete all
partitions. Then reboot the system to clear memory. Otherwise, the
old partitioning data will be reused.

Link Error Settings

• Invalid DWORDs: The number of invalid dwords that have been

received, outside of PHY reset sequences, since the last PHY Link
Error Reset.

• Loss of DWORD Sync: The number of times, since the last PHY

Link Error Reset, that DWORD synchronization was lost and the
link reset sequence occurred.

• Running Disparity Errors: The number of DWORDS with running

disparity errors that have been received, outside of PHY reset
sequences, since the last PHY Link Error Reset.

• PHY Reset Errors: The number of times the PHY reset sequence

has failed, since the last PHY Link Error Reset.

Threshold Count

Link error count threshold values. When a Link Error Count exceeds
a Threshold Count within the Threshold Time (secs) the Fusion-MPT
FW may reduce the link rate. Press Enter on any of these fields to
modify the value.
