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.
