Setting Unit Policies

• Override ECC (Continue on Source Error When Rebuilding).
Determines whether ECC errors are ignored when they are encountered
during a rebuild. (ECC errors are an indication of errors that have
occurred on a particular drive since it was last read.) When not enabled, a
rebuild will abort upon encountering an ECC error and the unit will be set
to Degraded. For details, see “Setting Overwrite ECC (Continue on
Source Error When Rebuilding)” on page 108.
• Queuing. Determines whether command queuing is enabled for the unit.
When enabled for drives that support it, this policy can improve
performance. For details, see “Enabling and Disabling Queuing for a
Unit” on page 110.
• StorSave Profile. Determines what StorSave profile is used for the unit.
Three profiles are available: Protection, Balanced, and Performance. For
details, see “Setting the StorSave Profile for a Unit” on page 111.
• 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, but, once Rapid RAID
Recovery is disabled for the unit, it cannot be re-enabled. For details, see
“Rapid RAID Recovery” on page 113.
