Working with mirrored arrays
Among the advanced tasks possible with the ACU GUI, you can split a mirrored array and then
recombine it. This process entails breaking a RAID 1 or RAID 1+0 mirror into two identical new arrays
consisting of RAID 0 logical drives.
Support for these procedures requires the following:
• The ACU GUI must be run in offline mode ("Configuring a server using ACU located on the
SmartStart CD" on page 26).
• Select controller models must have a valid SAAP license ("About SAAP" on page 8).
• Mirrored arrays being split can have RAID 1 or RAID 1+0 configurations. Arrays with other RAID
configurations cannot be split.
Several reasons exist for splitting and recombining a mirrored array. For more information, see the "RAID
1(+0): breaking mirrors and rebuilding drives" how-to white paper on the HP website
(http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00378986/c00378986.pdf
