Execute the following command to display the driver configuration

information, and then refer to the instance field of the HDLM driver

obtained in step 1 (the driver name of the HDLM driver is dlmfdrv).

Identify the path used to determine the HDLM logical device file name of

the LU from the FilterPath property.

# /usr/sbin/prtconf -vP

The following shows an example of executing the command.
This example shows the information on instance 1 of the HDLM driver

(the driver name of the HDLM driver is dlmfdrv), which is contained in

the output results of the prtconf command.
The shaded portion is the physical device file name of the sd or ssd driver

of the path used to determine the HDLM logical device file name.

Switching the Kernel Mode

If you switch the kernel mode from 32 bits to 64 bits when only the 32-bit

version of HDLM is installed, you must re-install HDLM after the switch is

completed.

When the Path Configuration Is Changed in a Boot Disk Environment

When HDLM changes the path used to determine the logic device file name of

an HDLM device, perform the procedures below. If this procedure is not

performed, the disk might fail to boot because the name of the physical

device file corresponding to the logical device file changed. To obtain the path

that HDLM uses to determine the logic device file name of an HDLM device,

execute the procedure described in

When the Path Configuration Is Changed

on page 4-17
