/cx show
The /cx show command shows summary information on the specified
controller /cx. This information is organized into a report containing two or
three parts:
• A Unit summary section listing all present units
• A Port summary section listing of all ports (or virtual ports) and disks
attached to them.
• A BBU summary section listing, if a BBU is installed on the controller.
The Unit summary section lists all present units and, for each one, 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, the write cache setting, the read cache setting (if
supported by your controller) and the autoverify 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 SATA+SAS RAID Controller Card Software User Guide, Version 10.2.
For controllers with read cache support, the Cache column shows 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 82.
This section lists the ports or virtual ports present, and for each port, specifies
the port or vport number, drive status, unit affiliation, drive type, phy number
Note: An asterisk (*) next to the status of a unit indicates there is an error on one of
the drives in the unit. This feature provides a diagnostic capability for potential
problem drives. The error might not be a repeated error, and might be caused by an
error correction code (ECC) error, Smart Monitoring Analysis and Reporting
(SMART) failure, or a device error. Rescanning the controller clears the drive error
status if the condition no longer exists
