8.2.3 RAID action for MDisks
Internal drives in IBM Flex System V7000 Storage Node are managed as Array mode
MDisks, on which several RAID actions can be performed. Select the appropriate Array
MDisk by clicking Pools  MDisks by Pools, and then click Actions  RAID Actions
(Figure 8-47).
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 321.
