The Advanced Adapter Properties menu provides access to advanced
Device Properties and PHY Properties. To modify the Link Error Settings
Threshold Count and Threshold Time, press Enter while the cursor is on
the desired field and enter the new value.
Table 9.9 describes the
Advanced Adapter Properties menu fields.
Table 9.9 Advanced Adapter Properties 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 non-volatile 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 that does
not have 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 sys-
tem to clear memory. Otherwise, the old partitioning data will be reused.
Link Error Settings The Link Error Settings are as follows:
•
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 firmware may reduce the
link rate. Press Enter on any of these fields to modify the value.
