Migrating RAID level and stripe size online

Using CPQONLIN, you can modify both the RAID level and stripe size of an
existing logical drive while online. To migrate a drive:

1. Select the drive setting option under the logical drive menu for the drive you

intend to modify.

2. Select the new RAID level and/or stripe size from the choices presented. If

the new settings are valid, the migration begins when you save the changes.
