usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/sda1 on /boot type ext3 (rw)
none on /dev/shm type tmpfs (rw)

is /dev/sda1.
c. Using an editor such as vi, change the LABEL specification to an sd
device specification.
(before)
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2

d. Install HDLM.
e. After configuring the HDLM device, execute the dlmcfgmgr -o
command to exclude the HDLM device that corresponds to the boot
disk as a management target.
• If the SCSI device name has been changed by using the udev function,
see
Settings for a Multipath Boot Disk Environment on page 3-142 and
Upgrade installation of HDLM in a Boot Disk Environment on page 3-151
and perform operations while reading the SCSI device names in those
subsections as the new SCSI device names (udev name) that were
changed by using the udev function.
In an environment where HDLM has been installed, you can use the
dlmcfgmgr utility to check the correspondence between a SCSI device and
a udev name.
The following shows an example of executing the dlmcfgmgr utility with
the -v and -udev parameters specified.
Figure 3-7 Example of Executing the dlmcfgmgr Utility with the -v
and -udev Parameters Specified
The HDevName, Device, and Udev columns display HDLM devices, SCSI
devices, and udev names, respectively.
