Adapter Properties Menu Options
Option Description
Battery Backup This entry indicates whether the selected controller has a BBU. If
present, you can click Present to view information about the BBU.
Set Factory
Defaults
Use this option to load the default MegaRAID ® WebBIOS CU settings.
The default is [No].
Cluster Mode Use this option to enable or disable Cluster mode. The default is
[Disabled]. A cluster is a grouping of independent servers that can
access the same data storage and provide services to a common set
of clients. When Cluster mode is disabled, the system operates in
Standard mode.
Rebuild Rate Use this option to select the rebuild rate for physical drives connected
to the selected adapter. The default is 30 percent. The rebuild rate is
the percentage of system resources dedicated to rebuilding a failed
drive. The higher the number, the more system resources devoted to a
rebuild.
BGI Rate Use this option to select the amount of system resources dedicated
to background initialization of virtual disks connected to the selected
adapter. The default is 30 percent.
CC Rate Use this option to select the amount of system resources dedicated to
consistency checks of virtual disks connected to the selected adapter.
The default is 30 percent.
Reconstruction
Rate
Use this option to select the amount of system resources dedicated to
reconstruction of physical disks connected to the selected adapter. The
default is 30 percent.
Adapter BIOS Use this option to enable or disable the BIOS for the selected adapter.
The default is [Enabled]. If the boot device is on the selected controller,
the BIOS must be enabled; otherwise, the BIOS should be disabled or
it might not be possible to use a boot device elsewhere.
Coercion Mode Disk coercion is a tool for forcing physical disks of varying capacities
to the same size so they can be used in an array. The coercion mode
options are [None], [128MB-way], and [1GB-way]. The default is
[None].
The number you choose depends on how much the
drives from various vendors vary in their actual size. We
recommend that you use the 1GB coercion mode option.
