Write journaling is disabled. All data flushing from controller cache will
be flushed to disk. If a BBU is present, this essentially disables the BBU
for this unit.
Incoming FUA (Force Unit Access) host requests will be honored.
balance
provides more data protection than perform mode but less data
protection than protect mode, and provides better performance than protect
mode but less performance than perform mode. When storsave is set to the
balance
mode, it means:
When the unit becomes degraded, the write cache will not be disabled.
Write journaling is disabled, if no BBU is present, and is enabled, if a
BBU is present. All data flushing from controller cache will be flushed to
media if a BBU is installed and enabled. Otherwise, data will be flushed
to disk only.
Incoming FUA (Force Unit Access) host requests will be honored unless a
BBU is installed and enabled, in which case, they will be ignored.
For additional information, see “Setting the StorSave Profile for a Unit” in the
3ware 9550SX Serial ATA RAID Controller User Guide

This feature only applies to 9000 series controllers.
This command allows you to change the existing configuration of a unit with
type=RaidType
. You can make three types of changes:
Increase the capacity
Change the RAID level (with the same or increased capacity)
Change the stripe size
The unit that results from the migration is subject to the same rules and
policies that apply when creating a new unit with the
/cx add
command. For
example, a valid number of disks and parameters must be specified.
The destination unit must use all source disks and potentially augment the
number of disks in the
disk=p:-p
disk list. Unspecified parameters are
assigned the default values (stripe size of 64K, write cache enabled,
autoverify disabled, and ignoreECC disabled). Both source name and serial
number will be carried over to the destination unit.
