Online Migration

Use the Online RAID Level and Stripe-Size Migration screen to:

■Reconfigure a currently configured logical drive to a new fault-tolerance (RAID) level.

■Move an existing logical drive’s stripe size to a new stripe.

Both can be done online without causing any data loss.

Procedure—Performing Online RAID

Level Migration and Online Stripe-Size

Migration

To bypass the configuration wizard and manually perform online RAID level migration and online stripe-size migration:

1.Access the Online RAID Level and Stripe-Size Migration screen.

2.Choose a RAID level.

3.Choose a stripe size.

4.Click Done.
