The iSCSI Software Interface Driver

iSCSI Software Interface Driver Management

If the iscsiutil command is directed to the /dev/isw device file, the command is explicitly directed to the

iSCSI SWD. Most command sequences require root or super user permission. The iscsiutil command can

be used to:

• Display the iSCSI Software Interface Driver statistics:

# iscsiutil /dev/isw -s -G

-G displays the iSCSI Software Interface Driver global statistics.

• Clear the iSCSI Software Interface Driver statistics:

# iscsiutil /dev/isw -c -G

• Display the iSCSI Software Interface Driver name and version:

# iscsiutil /dev/isw

The iscsiutil tool requires the /dev/isw device file for its access to the iSCSI Software Interface Driver.

This file will be created when the iSCSI Software Interface Driver is installed.

Device files are created to access the iSCSI transport and Software Interface Drivers:

The iSCSI Software Interface Driver provides a low level interface to the network stack.

The /dev/isw device file, which is created during installation, provides an interface to the iSCSI

Software Interface Driver.
