▼ Create a Hardware Mirrored Volume
1. Verify which hard drive corresponds with which logical device name and
physical device name, using the raidctl command:
See “Disk Slot Numbers” on page 35.
The preceding example indicates that no RAID volume exists. In another case:
In this example, a single volume (c1t0d0) has been enabled.
The SPARC Enterprise T5140 or T5240 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:
■ OPTIMAL – Indicating that the RAID volume is online and fully synchronized.
■ SYNC – Indicating that the data between the primary and secondary member
disks in an IM are still synchronizing.
■ DEGRADED – Indicating that a member disk is failed or otherwise offline.
