LSI SYM8953U manual Is moved between adapters from different vendors

Table 3.3	Adapter Properties Fields and Descriptions (Cont.)
Field		Field Type	Descriptions
		[Value]
CHS Mapping		Configuration	Defines how the Cylinder Head Sector (CHS) values
		[SCSI Plug and Play	are mapped onto a disk without pre-existing partition
		Mapping / Alternate	information.
		CHS Mapping]	SCSI Plug and Play Mapping 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.
			Caution: Neither of these options has any effect after
			a disk has been partitioned using the FDISK
			command. The FDISK utility is a tool that the user can
			use to delete partition entries, one or all of them. If all
			partition entries are deleted, it is necessary to reboot
			to clear memory or 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		Configuration	Indicates the delay in seconds between spinups of
(Seconds)		[1 to 15]	devices attached to an adapter. Staggered spinups
			balance the total electrical current load on the system
			during boot. The default value is 2 seconds.
Secondary Cluster		Configuration	Indicates whether an adapter has one or more
Server		[Yes / No]	devices attached that are shared with one or more
			other adapters and therefore, the Symbios SCSI
			BIOS should avoid SCSI bus resets as much as
			possible.
			This option allows the user to enable an adapter to
			join a cluster of adapters without doing any SCSI bus
			resets. This is a requirement for Microsoft Cluster
			Server. The default value is No with an alternate
			option of Yes.
Termination Control		Configuration	If available, the field indicates whether an adapter has
		[Auto / Off]	automatic termination control.
			Auto means that the adapter automatically
			determines whether it should enable or disable its
			termination. Auto is the default state unless
			termination is done manually, in which case, the
			configuration is Off.
<Restore Defaults>		Executable	Press Enter to obtain default settings.
