Emulex LP1150-F4 user manual Modes of Operation emlxdrv, Interactive Mode emlxdrv

Using the emlxdrv Utility

The emlxdrv utility is used for binding (associating) the Emulex emlxs (Leadville FC) driver and the Emulex lpfc (traditional non-Leadville FC) driver to the various models of Emulex FC HBAs. This allows both drivers to coexist in the same host and attach to mutually exclusive Emulex FC HBA models. In other words, the emlxs driver can be configured to attach and operate one set of HBA models, while the lpfc driver can be configured to attach and operate a different set of HBA models. However, Solaris does not allow both drivers to attach and operate the same model of HBA even if there are multiple HBAs of that model present. If the driver binding configuration is changed, the host system must usually be rebooted for the new configuration to take effect.

Modes of Operation (emlxdrv)

The emlxdrv utility program can be run in two modes:

•Interactive

•CLI

Interactive Mode (emlxdrv)

Run the emlxdrv utility program in interactive mode by typing the name of the program without any command line arguments:

# emlxdrv

After it is started, the emlxdrv program scans the host system and prepares a driver configuration table consisting of bindings (associations) between the emlxs and lpfc drivers and a list of Emulex FC HBA models. After the table is prepared, the utility displays the following:
