Figure 8-47 RAID actions on Array MDisks
You can choose the following RAID actions:
򐂰 Set Spare Goal: You can set the wanted number of spare drives that is required to protect
the array from drive failures. If the number of drives assigned as Spare does not meet the
configured spare goal, an error is logged in the event log that reads “Array MDisk is not
protected by sufficient spares”. This error can be fixed by either replacing failed drives,
which occupy a spare drive, or by adding additional drives as spare drives. Remember
that during the internal drive configuration that automatically spare drives are assigned
according to the chosen RAID preset’s spare goals, as described in 8.1.2, “Configuring
internal storage” on page 303.
򐂰 Swap drive: The Swap Drive action can be used to replace a drive in the array with
another drive with the status of Candidate or Spare. This action is used to replace a drive
that has failed, or is expected to fail soon. For example, as indicated by an error message
in the event log. Select an MDisk containing the drive to be replaced and click RAID
Actions  Swap Drive. In the Swap Drive window (Figure 8-48 on page 330), select the
member drive to be replaced and click Next.
