The following table lists the migrations supported by Adaptec Storage Manager.

Some operating systems for example, Windows XP, Windows 2000, Windows NT and Novell NetWare, support Online Capacity Expansion (OCE). This allows you to use the additional capacity when the array expansion is completed without having to reboot the system. If you are using these operating systems, refer to your operating system documentation for instructions on using the additional capacity.

Array Modification Rules

  1. The capacity of the new array must match or exceed the capacity of the current array.

  2. If the capacity and/or RAID type of the new array requires greater total drive capacity than the current array, the additional capacity must be on drives that are not already used in the current array.

Modifying an Array

To modify an array:

  1. Click the Modify in the Logical Devices view.

  2. Select the array that you want to modify.

  3. Select the RAID level that you want to migrate the array to, or
    if you want to expand the capacity of the existing array, select the current RAID level.

  4. Optional. Click Advanced to select a new stripe size for the new or existing array.

  5. If necessary, select the additional drive(s) required for capacity expansion, or necessary to support the new RAID level.

  6. Optional. Click Advanced to change the priority for the task.

  7. Click Finish.
