Fibre Channel information

Command for displaying Fibre Channel information

You use the fcstat command to display the following types of information:

Link statistics for all disks on a loop
Internal statistics kept by the Fibre Channel driver
Information showing the correlation of disks with disk shelves and the relative physical positions of drives on a loop

For more information about the fcstat command, see the na_fcstat(1) man page.

Link statistics for all disks on a loop

The fcstat link_stats command displays link statistics for disks on a loop. This display includes the link failure count, the loss of sync count, the loss of signal count, the invalid cyclic redundancy check (CRC) count, the frame in count, and the frame out count.

Internal Fibre Channel driver statistics

The fcstat fcal_stats command displays internal statistics kept by the Fibre Channel driver. The Fibre Channel driver maintains statistics about various error conditions, exception conditions, and handler code paths executed.

Relative physical drive position

The fcstat device_map command displays the relative physical positions of drives on a loop and the mapping of devices to disk shelves.

Getting Fibre Channel information using the stats command

You can also get Fiber Channel information, either interactively or with a script, using the fcp object for the stats command. For more information about the stats command, see Getting storage system information using the stats command.
