Port Object Commands

/cx/px show ncq

This command applies only to 9550SX, 9590SE, and 9650SE model controllers.

This command displays the NCQ (Native Command Queueing) information for the drive attached to the specified port, including whether NCQ is supported by the drive, and whether it is enabled at the drive.

For queuing to be used, it must be enabled for the unit and supported by the drive.

Example:

//localhost> /c0/p5 show ncq /c0/p5 NCQ Supported = No /c0/p5 NCQ Enabled = No

/cx/px show lspeed

This command applies only to 9550SX, 9590SE, and 9650SE model controllers.

This command displays the maximum SATA link speed supported by the drive attached to the port and the present SATA link speed setting.

Example:

//localhost> /c0/p5 show lspeed

/c0/p5 SATA Link Speed Supported = 3.0 Gb/s /c0/p5 SATA Link Speed = 3.0 Gb/s

/cx/px show capacity

This command displays the capacity of the drive attached to the specified port in two formats—GB and blocks. Note that of this version, the GB format is computed based on division by 1000 (not 1024).

Example:

//localhost> /c0/p5 show capacity 149.05 GB (312581808 Blocks)

/cx/px show smart

This command extracts SMART (Self Monitoring Analysis and Reporting) data from the specified disk. Because the data is extracted live from the disk, this command can be used to get the most recent data about the presence or absence of a disk.

The SMART data is displayed in hexadecimal form.
