Optional: From the drop down menu, select either
On-the-fly initialization
or
Performance evaluation
.
On-the-fly initialization
– ExaSAN RAID systems
record the initialized sectors in the bitmap. All
sectors are initialized only once. The entire
initialization process will be completed faster and
the performance will be better during the
initialization.
During on-the-fly initialization, 65-75% of the full
speed (of a created RAID) is still available. You
can still use the RAID system during the RAID
initialization.
Select this option (default) to ensure the
completeness of the array. If this option is
selected, it will recalculate the disk parity and
data organization (how it is arranged). The
amount of time required for the initialization
process varies depending on the disk volume.
Performance evaluation
– Select to evaluate the performance of the target array. Data
and parity are not initialized. (No data protection when this mode is on).
Note
Once you click
Create Array
and you have selected On-the-fly
initialization, you will see the initializing % on the Main screen.
You will be able to use and configure the array immediately if it is
created using On-the-fly initialization. However, the RAID
performance of the array will be slightly lower than usual before
the initialization is complete.
5. Assign LUN automatically
Check this box to automatically assign a LUN. You may choose to assign LUN manually
under
Options
. However, you will not be able to use the RAID volume until it has been
assigned a LUN.
6. Click
Create Array
to complete the process.
