/cx/ux set rapidrecovery all|rebuild|disable [quiet]
This command only applies to 9000 series controllers, models SE and SA, and
only for redundant units. Firmware 9.5.1 or later is required.
This command sets the Rapid RAID Recovery policy for the specified unit.
Rapid Raid Recovery can speed up the rebuild process, and it can speed up
initialize and verify tasks that may occur in response to an unclean system
shutdown. Setting this option to
all
applies this policy to both these situations.
Setting it to
rebuild
applies it only to rebuild tasks. If the policy is set to
disable
, then none of the tasks will be sped up.
There is some system overhead from setting rapidrecovery to
all.
If you have
a BBU, you can set rapid recovery to
rebuild,
as a BBU provides protection
against data loss in the event of an unclean shutdown.
Once this attribute is set, the policy remains in effect unless it is changed or
disabled for the unit.
Note:
Once disabled, this setting cannot be changed for
the unit at a later time.
The quiet option is provided for scripting purposes, and is applicable only to
the
disable
option. (
/cx/ux set rapidrecovery=disable quiet
)
Example:
//localhost> /c0/u0 set rapidrecovery=all
Setting Rapid RAID Recovery policy on /c1/u0 to [all] ... Done.
/c

/u

set storsave=protect|balance|perform [quiet]
This feature only applies to 9000 series SX/SE/SA model controllers.
This command sets the storsave policy to be either
protect
,
balance,
or
perform
when the unit write cache is enabled. The default setting is
balance
when a BBU is installed, and
perform
whan a BBU is not installed.
The storsave policy adjusts several factors that control the balance between
protection and performance on a unit. There is a trade-off among the available
settings. The following description about the settings should help you to
decide which one is suitable to you and your application. You will find further
discussion of this setting in the
3ware SAS/SATA RAID Software User Guide,
Version 9.5.1
, under “About StorSave Profile Levels” on page 124.
Note:
When upgrading to 9.5.1, redundant units created using firmware versions
prior to 9.5.1 are assigned a Rapid Recovery Policy of disable, which cannot be
changed.
