Does my controller support this feature? See "Appendix: Supported Features."

The Online and Offline tasks only apply to physical disks that are included in a redundant virtual disk and attached to a PERC 3/SC, 3/DCL, 3/DC, 3/QC,4/SC, 4/DC, 4e/Si, 4e/Di, 4e/DC, 4/Di, or CERC ATA100/4ch controller.

Use the Offline task to deactivate a disk before removing it. Use the Online task to reactivate an offline disk.
