Sun Blade T6340 Server Module Installation and Administration Guide • April 2010
The preceding example indicates that no RAID volume exists. In another case:
In this example, a single volume (
c1t0d0
)
has been enabled.
The 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.
■
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
GOOD
, indicating that it is online and functioning properly, or it might be
FAILED
, indicating that the disk has hardware or configuration issues that need to
be addressed.
For example, an IM with a secondary disk that has been removed from the chassis
appears as:
#
raidctl
Controller: 1
Volume:c1t0d0
Disk: 0.0.0
Disk: 0.1.0
Disk: 0.2.0
Disk: 0.3.0
Disk: 0.4.0
Disk: 0.5.0
Disk: 0.6.0
Disk: 0.7.0
#
raidctl -l c1t0d0
