Initialize LUNs in Background (Configuration Function Menu)
Background initialization makes uninitialized system drives consistent by setting the
parity while allowing the host to have instantly available read and write access to the
system drive. Background initialization is implemented only in version 7.75 and later
firmware.
Note: Background initialization can only be performed on valid RAID levels (RAID
levels 1, 3, 5 and 0 +1)
Background initialization is enabled by default. If the "Enable Background Init"
controller parameter is changed and set to disabled, "Initialize LUNs in Background" will
not be displayed under "Configuration Functions". The option to perform a background
initialization is still provided under the "Initialize LUN(s)" function. However, only one
LUN can be selected for background initialization at a time using this function. When
performing "Background Init" on multiple LUNs, change the "Enable Background Init"
parameter under the View/Modify RAID Controller Configuration. See Figure 3-56 on
page 93.
To initialize LUNs in the background, follow these steps:
1. Click Initialize LUNs in Background on the main menu.
The screen shown in Figure 3-42 appears.
