The
Unit
summary section lists all present unit and specifies their unit
number, unit type (such as RAID 5), unit status (such as INITIALIZING), %R
(percent completion of rebuilding), % V/I/M (percent completion of
verifying, initializing, or migrating), stripe size, size (usable capacity) in
gigabytes or terabytes, the write cache setting, the read cache setting (if
supported by your controller) and the auto-verify policy status (on/off)
Possible unit statuses include OK, RECOVERY, INOPERABLE,
UNKNOWN, DEGRADED, INITIALIZING, INIT-PAUSED, VERIFYING,
VERIFY-PAUSED, REBUILDING, REBUILD-PAUSED, MIGRATING, and
MIGRATE-PAUSED. Definitions of the unit statuses are available in the
3ware SAS/SATA RAID Software User Guide, Version 9.5.1
.
For controllers with read cache support (9650SE and newer controllers with
release 9.5.2 or later), the 'Cache' column displays the settings of both the read
cache and the write cache.
Below is a summary of the possible settings in the Cache column:
W - only the write cache is enabled
Rb - only the read cache Basic Mode is enabled
Ri - only the read cache Intelligent Mode is enabled
RbW - the read cache Basic Mode and the write cache are both enabled
RiW - the read cache Intelligent Mode and the write cache are both enabled
OFF - all caches are disabled
Note that when the Intelligent Mode of the read cache is enabled, the Basic
Mode features are also enabled. For details, see “/cx/ux set
rdcache=basic|intelligent|off” on page 94
.
For earlier controllers, the Cache column displays only the write cache setting
of ON or OFF
For controller models up to the 9650SE series, the
Port
summary section lists
all present ports and specifies the port number, disk status, unit affiliation, size
(in gigabytes) and blocks (512 bytes), and the serial number assigned by the
disk vendor.
For the 9690SA controller series, this section lists virtual ports, and specifies
the VPort number, disk status, unit affilication, drive type, phy number ( if
direct attached), the enclosure and slot (if expander attached), and model
number of the drive.
The
BBU
summary lists details about the BBU, if one is installed. It includes
a few important attributes such as hours left (in which the current BBU can
Note:
If an asterisk (*) appears next to the status of a unit, there is an error on one
of the drives in the unit. This feature provides a diagnostic capability for potential
problem drives. The error may not be a repeated error, and may be caused by an
ECC error, SMART failure, or a device error. Rescanning the controller will clear the
drive error status if the condition no longer exists
