6.8 Sparing Strategy

It is recommended that you reserve a spare disk in the configuration of the system

for use as a replacement when a hardware error occurs on another disk in the

system. The Sparing Strategy screen is used to set (or modify) the strategy used

and to assign (or unassign) a disk as a spare.

The sparing strategies available are:

 Global - A disk that can be used by any RAID on the system that has

global sparing strategy selected.

 Local - A disk that can only be used by the RAID in which it was added to.

NOTE: A RAID that has a local spare cannot use the global spare.

 None - The RAID selected cannot use the global spare and does not have a

local spare assigned. The RAID cannot be re-built automatically.

6.8.1 Creating a Hot Spare

Select/change a sparing strategy from the RAID Functions Î Create Hot Spare

screen as follows:

1. If a global spare is required, select the row where the Global option is

listed. If a local spare is required for a particular RAID, select the according

row by ticking the radio button for that row.
