Switching The Kernel Mode; When The Path Configuration Is Changed In A Boot Disk Environment - Hitachi XP P9500 User Manual

2 Obtain path information from the instance number of the HDLM driver.
.
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.
For details on how to switch the kernel mode currently being used, see

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
on page
3-41.
