4. HDLM Operation
289
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.
(3) 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.
For details on how to switch the kernel mode currently being used, see (5) Switch the
Kernel Mode of 3.5.1 Preparations for a New Installation of HDLM.
(4) 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
(2) When the Path Configuration Is Changed.
