4-50 Configuring Your Server
Create RAID via allows you to select between the different creation methods for RAID0
and RAID1. The following table gives examples of when each is appropriate.
RAID level Create RAID
via How to create
RAID0 No Init Creates a RAID0 on new drives.
RAID0 Migrate Adds a new drive to the existing drive that contains data
(migration). The server does not support [Migrate] feature.
RAID1 Build* Copy the data in the existing drive and creates RAID1
drive.
RAID Clear Clears all the data in the drive and creates new RAID1
drive.
RAID1 Quick Init Fastest way to create a RAID1 drive.
* When you start creating RAID, a window to select the copy source drive (existing drive)
appears. The data in the selected drive is copied to the new drive to configure RAID. Note
that the data in the destination drive is erased.
IMPORTANT:
The server does not support Migrate option.
NOTES:
„
Before adding a new drive to an existing array, back up any data
contained on the new drive. Otherwise, all data will be lost.
„
If you stop the Build process on a RAID1 from ACU, you can only
restart it from Adaptec Storage Manager - Browser Edition or
Adaptec Storage Manager.
„
A RAID1 created using the Quick Init option may return some data
miscompares if you later run a consistency check. This is normal
and is not a cause for concern.
„
The ACU allows you to use drives of different sizes in a RAID1.
During a build operation however, only the smaller drive can be
selected as the copy source or first drive.
„
We do not recommend that you build an array on Windows dynamic
disks (volumes), as it will result in data loss.
