* The logical device names might appear differently on your system, depending on the number and type of add-on disk controllers in-
stalled.

▼ To Create a Hardware Mirrored Volume

1. Verify which hard drive corresponds with which logical device name and
physical device name, using the raidctl command:
# raidctl
No RAID volumes found.

The preceding example indicates that no RAID volume exists. In another case:
# raidctl

In this example, a single IM volume has been enabled. It is fully synchronized
and is online.
The Sun Netra T5440 server's on-board SAS controller can configure as many as
two RAID volumes. Prior to volume creation, ensure that the member disks are
available and that there are not two volumes already created.
The RAID status might be:
