3DM 2 Reference Drive and choosing Properties; then on the Tools tab, click Check Now. Under Linux or FreeBSD use the fsck utility command. For example, fsck /dev/ sda1. Note: The policy Overwrite ECC is equivalent to the "Continue on Source Error" option in 3BM and the "IgnoreECC" option in the CLI. Queuing. (Not applicable for SAS drives) This policy enables or disables Native Command Queuing (NCQ) for SATA drives in the unit. By default, queuing is disabled. You can enable it, if desired. NCQ only operates when the feature is enabled at both the drive and the controller. If a drive does not support NCQ, the policy setting for the controller is ignored. Enabling NCQ can improve performance in many applications; it causes command reordering to be done on the drive itself. StorSave Profile. The StorSave feature includes an option that lets you change the StorSave Profile used for a unit. Three profiles are available: Protection, Balanced, and Performance. These profiles automatically adjust several different factors that affect protection and performance, including whether FUA (Forced Unit Access) is honored, whether Write Journaling is enabled, and whether Disable Cache on Degrade is enabled. For additional information, see "Setting the StorSave Profile for a Unit" on page 123. Note: If the write cache setting is disabled for a unit, the StorSave Profile capability does not apply and is automatically disabled. Rapid RAID Recovery. Determines which Rapid RAID Recovery option to use, All, Rebuild or Disable. All will apply the policy to both rebuilds and unclean shutdowns. Rebuild will apply only to rebuilds. You can switch between All and Rebuild settings. However, once Rapid RAID Recovery is disabled for the unit, it cannot be re-enabled. For additional information, see "Rapid RAID Recovery" on page 126. Unit Names Units can be assigned names. A name can be assigned when the unit is created and can be changed from this screen. For additional information, see "Naming a Unit" on page 115. 226 3ware SAS/SATA RAID Software User Guide, Version 9.5.1
