Models 9500S, 9550SX, and 9590SE The quiet attribute turns off interactive mode. /cx/ux set identify=on|off This feature only applies to 9550SX, 9590SE, and 9650SE model controllers. This feature requires an enclosure that uses an integrated AMCC/3ware CCU (chassis control unit). (Check the 3ware web site for a list of chassis vendors that support enclosure services, as they become available.) For additional information about enclosure-related commands, see “Enclosure Object Commands” on page 87. This command allows you to identify a unit within an enclosure by blinking the LEDs associated with the drive slots of the specified unit. Example: //localhost> /c0/u0 set identify=on Sending Identify request for unit /c0/u0 to [on] ... Done. /cx/ux set ignoreECC=on|off This feature only applies to 9000 series controllers. This command allows you to set the ignoreECC policy for a given unit. When ignoreECC policy is set to off, if a rebuild process encounters bad sectors on the source disk, the rebuild will fail. When ignoreECC is set to on, such errors are ignored, and the rebuild will continue. When you use ignoreECC, a file system check is recommended following the rebuild, to insure data integrity. By default, ignoreECC is off. See Table 8, “Supported Model-Unit Types for ignoreECC,” on page 42 Chapter 2. CLI Syntax Reference /cx/uxset name=string This command allows you to name the unit with an arbitrary name. You can use this name in conjunction with the unit serial number to cross-reference with the unit. The system does not check to ensure uniqueness of names, so be careful to assign different names to each unit. Note: The unit’s serial number is automatically assigned when the unit is created and is not changeable. /cx/ux set qpolicy=on|off This command applies only to 9550SX, 9590SE, and 9650SE controllers. This command sets the queue policy of the firmware. If the queue policy is on, the firmware utilizes the drive queueing policy. If some of the drives in the unit do not support any queueing policy, this policy will have no effect on those drives. By default, qpolicy is on. Example: //localhost> /c0/u5 set qpolicy = on Setting Command Queuing Policy for unit /c0/u5 to [on] ... Done. /cx/ux set storsave=protect|balance|perform [quiet] This command applies only to 9550SX, 9590SE, and 9650SE 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 protect. 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 Serial ATA RAID Controller User Guide, under “About StorSave Profile Levels” on page 117. 3ware Serial ATA RAID Controller CLI Guide Unit Object Commands protect provides the maximum data protection among the controller settings. When storsave is set to protect mode, it means: • When the unit becomes degraded, the write cache will be disabled. • Write journaling is enabled. All data flushing from controller cache will be flushed to media. • Incoming FUA (Force Unit Access) host requests will be honored unless a BBU is installed and enabled, in which case, they will be ignored. perform provides the maximum performance and least data protection of the three controller settings. When storsave is set to perform mode, it means: • When the unit becomes degraded, the write cache will not be disabled. • 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. If you set the storsave policy to perform, a confirmation message will warn you that there could be data loss in the event of a power failure. 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. quiet is used for non-interactive mode. No confirmation is given and the command is executed immediately. This is useful for scripting purposes.
