6.1.2 Online RAID Level Migration

RAID level migration allows you to migrate from a specific level of array to another one. This function allows online RAID level migration or online RAID expansion, even when the system is carrying out I/O. You do not have to restart the system. Together with mirror split, this function provides a complete system backup and repair strategy.

Notes: 1. You can not migrate major RAID levels to minor ones. A new RAID level needs to be of the same level or higher than the original array.

2.If the system fails during migration, once the system is restarted, the migration will continue.

3.If the hard disk were damaged during migra- tion, as long as both arrays before and after the migration are available with fault tolerance, no data would be lost.

4.Online RAID level migration can build a maxi- mum array capacity of 2.199TB (1MB = 1,000,000 bytes and 1TB = 1,000,000MB).

Online RAID level migration:

1.Select the array to split using the right button of the mouse.

2.On the array menu, select Transform. The Online RAID level migration window appears (as shown below).
