Adding or Configuring Spare Drives
When adding a spare drive to an array, there must be an unassigned drive or a drive
already assigned as a spare on another array. You can assign a single spare to any
number of arrays or assign separate spares. When you select Assign Spare Drive,
only drives that qualify will appear (for example, only those spares that are large
enough will appear). If drives that you expect to see do not appear, switch to the
physical drive view (Tab key), and check the size of the drives. The capacity of the
spare must be equal to or greater than the capacity of the smallest drive in the array.
Online RAID and Stripe Migration
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 to you.
If the new settings are valid, the migration will begin when you save the changes.
Failed Drives or Interim Recovery Mode
If a drive fails and hardware fault tolerance is enabled, operation continues. Replace
the drive as soon as possible. Select a logical drive and press the F3 key to monitor
the status of drive recovery.
