ICPCON then creates and configures the new host drive and adds it to the list on the
Select Host Drive screen (see
Figure 10-102 ). All SCSI parameters are adjusted to the
optimum values.
Figure 10-102. Newly Created Host Drive
ICPCON begins the build process on the new host drive. In the example, it calculates the
parity information and writes it to the hard disks. The status during this process is
build
(for more details regarding the status definitions, refer to Section 10.4.1.2 ).
When the build is successfully finished, the status changes to ready . You can press <F10>
to refresh the screen and see the updated status of the host drive.
The type of initialization build determines how the redundancy information is calculated.
There are 2 build types, the Destructive Build and the Non-destructive Build. Only
available if ICPCON is loaded with <Ctrl>+<G>, the Destructive Build deletes any data
by writing a "0" pattern across all hard disks. This initialization process is very fast since
no read IOs or parity calculation is involved. However, the initialization build must be
successfully finished before leaving ICPCON, otherwise the build mode is automatically
changed to Non-destructive during the next boot. The Non-destructive Build reads the
data blocks, calculates the parity from the contents of the data blocks, and stores it to the
corresponding sectors on the disks. This process takes 5-10 times longer than the
Destructive Build typically, but the Non-destructive Build can run in the background, for
example, during the installation of the operating system.
Note:
After escaping from ICPCON during the first RAID 5 initialization build, ICPCON
displays the screen shown in
Figure 10-103 . Although ICPCON indicates the first RAID 5
