• If the SCSI device name has been changed by using the udev function,
see Settings for Using an HDLM Device as a Boot Disk on page 3-137 and
Upgrade Installation in an Environment Where an HDLM Device Is Used as
a Boot Disk on page 3-147 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.
