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:
See
“Physical Disk Slot Numbers, Physical Device Names, and Logical Device
Names for Non-RAID Disks” on page 53
.
The preceding example indicates that no RAID volume exists. In another case:
In this example, a single IM volume has been enabled. It is fully synchronized
and is online.
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:
■
OK
– Indicating that the RAID volume is online and fully synchronized.
■
RESYNCING
– 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.
■
FAILED –
Indicating that volume should be deleted and reinitialized. This
failure can occur when any member disk in an IS volume is lost, or when both
disks are lost in an IM volume.
The Disk Status column displays the status of each physical disk. Each member
disk might be OK, indicating that it is online and functioning properly, or it might
be FAILED, MISSING, or otherwise OFFLINE, indicating that the disk has
hardware or configuration issues that need to be addressed.
