Mapping [SCSI
Plug and
Play
Mapping/
Alternate
CHS
Mapping] without pre-existing partition information.
SCSI Plug and Play Mapping (default) automatically determines the most
efficient and compatible mapping.
Alternate CHS Mapping uses an alternate, possibly less efficient, mapping
that may be required if a device is moved between adapters from different
vendors.
CAUTION: Neither of these options has any effect after a disk has
been partitioned using the FDISK command. FDISK is a tool that you
can use to delete one or all partition entries. If you delete all partition
entries, you must reboot to clear the memory. Otherwise, the old
partitioning data will be reused, thus nullifying the previous
operation. Use care to ensure that the correct disk is the target of an
FDISK
command.
Spinup
Delay
(secs) Configuration
[1 to 15]
Indicates the delay in seconds between spinups of devices attached to an adapter.
Staggered spinups balance the total electrical current load on the system during
boot. The default value is 2 seconds.
NOTE: Your hard disk drives may require a jumper to be installed
before this setting will work. Please refer to your hard disk drive
documentation.
Secondary
Cluster
Server Configuration
[Yes/No] Indicates whether an adapter has one or more devices attached that are shared
with one or more other adapters. Therefore, the Fusion-MPT SCSI BIOS should
avoid SCSI bus resets as much as possible.
This option allows you to enable an adapter to join a cluster of adapters without
doing any SCSI bus resets. This is a requirement for the Microsoft Cluster Server.
The default value is No.
Termination
Control Configuration
[Auto/Off] If available, the field Indicates whether an adapter has automatic termination control.
If not available, its current status is either Auto or Off.
Auto (default) means that the adapter automatically determines whether it
should enable or disable its termination.
Off means termination on the adapter is off and the devices at the ends of
the SCSI bus must terminate the bus.

Device Properties Menu
The Device Properties menu allows you to view and update individual device settings for an adapter. Table 2-4. lists
