Assigning Array Properties
Once you've create a new array, you are ready to assign the properties to the ar-
ray.
*Caution: Once the array is created and its properties are assigned, you cannot
change the array properties using the ACU. You will need to use the Adaptec Storage
Manager - Browser Edition. (Refer to Adaptec's User's Guide in the enclosed CD.)
To assign properties to the new array:
1. In the Array Properties menu, select an array type and press Enter.
Note that only the available array types: RAID 0, and RAID1, are displayed on the
screen. (*RAID 0 or RAID 1 requires two drives.)
2. Under the item "Arrays Label", type in an label and press Enter. (Note: The label
shall not be more than 15 characters.)
3. For RAID 0, select the desired stripe size. (Note: Available stripe sizes
are 16, 32, and 64 KB-default. It is recommended that you do not change the default
setting.)
4. The item: "Create RAID via" allows you to select between the different creating
methods for RAID 0 and RAID 1.
The following table gives examples of when each is appropriate.
(Note:
If you select Migrate for RAID 0, or Build for RAID 1, you will be asked to
select the source drive. The contents of the source drive will be preserved. However,
the data on the new drive will be lost.)
5. When you are fi nished, press Done.
Notes:
1. Before adding a new drive to an array, back up any data contained on the new
drive. Otherwise, all data will be lost.
2. If you stop the Build or Clear process on a RAID 1 from ACU, you can restart it by
pressing Ctrl+R.
3. A RAID 1 created using the Quick Init option may return some data mis-matches if
you later run a consistency check. This is normal and is not a cause for concern.
Raid Level Create Via When Appropriate
RAID 0 No Init Creating a RAID 0 on new drives
RAID 0 Migrate
(*Note)
Creating a RAID 0 from one new drive and
one drive with data you wish to preserve
RAID 1 Build1 Any time you wish to create a RAID 1, but especially if
you have data on one drive that you wish to preserve
RAID 1 Clear Creating a RAID 1 on new drives, or when you want to
ensure that the array contains no data after creation.
