This field regulates the mode of data resiliency that the
disk array will operate in. The "Normal" mode is set at the
factory when dual controllers are ordered with the array.
when only one controller is present. When enabled, the
disk array will assert a Single Controller Warning when
there are not two controllers present in the array disk
array. When disabled, no Single Controller Warning will
be indicated.
TRUE Controls the modification of the Write Cache setting.
When LCWO is set to true, then the host cannot change
the Write Cache setting. When LWCO is false, the host
will be able to change Write Cache setting.
FALSE Enables the disk array response to the Write Cache
setting. If false, NVRAM use does not depend on the
Write Cache setting, and will be enabled if no other
condition inhibits it. If true, then NVRAM is disabled when
Write Cache is disabled
TRUE Couples the use of NVRAM to the presence of an
operational dual controller. If true and no operational dual
controller is present, then NVRAM use is disabled.
Otherwise NVRAM use does not depend on the presence
of the second controller, and will be enabled if no other
condition inhibits it.
FALSE Couples use of NVRAM to the presence of an operational
UPS or BBU. At the time of printing, this field is reserved
for future functionality with UPS and is disabled in all
resiliency modes.
