Menu Advanced Setup: Configure Array Drives, Create New Array Drive - ICP RS Series User Manual

J.4.6.13 Menu Advanced Setup: Configure Array Drives, Create new Array Drive
After pressing ENTER, ICPCON lists all free Logical Drives, which are free (not yet part of
Array / Host Drives). The selection bar can be moved with the cursor up/down keys and the
Logical Drives can be selected/deselected with the SPACE bar.
The "M" means Master. For a striping array (RAID 0, 4, 5, 10), this is the first Logical Drive in
the array. For a RAID 1 (mirroring) array this is the Logical Drive which contains the valid
data and which should be copied to the second Logical Drive. After pressing ENTER
ICPCON displays a list of possible RAID levels. ICPCON
will ask you for the Stripe Size. This is the size of the
stripes into which the data is divided. Valid values are
16KB, 32KB, 64KB or 128KB. The default is 128KB.
The Build Type decides how the redundancy information is
created. The Destructive Build (which is only available if
ICPCON was loaded with <CTRL><G> ) fills all hard disks
with "0" and no further parity calculation is necessary. This
build method is pretty fast, but the build must be successfully finished before you can
leave ICPCON (otherwise the build mode is automatically changed to Non-destructive
during the next boot). The Non-destructive build really calculates the redundancy informa-
tion from the contents of the data stripes. It takes longer, but can run in the background,
i.e., during the installation of the operating system.
This security request has to be taken seriously. If you confirm with <Y> all data are lost.
If necessary you can limit the Array Drive's capacity. For this example we take the complete
capacity.
