Settings for Using an HDLM Device as a Boot Disk
This subsection describes how to perform a new installation of HDLM in a
single-path boot disk environment that uses a SCSI device and how to set up
the environment.
Note that if the settings are incorrect, the OS might not start. For details
about what action to take if the OS cannot be started from an HDLM device,
see Countermeasures for Unsuccessful Startup of the OS from an HDLM
Device on page 3-150 .
The name of the boot loader configuration file used in these procedures
differs depending on the boot loader and OS. The names of the boot loader
configuration files are listed in Table 3-53 Names of Boot Loader
Configuration Files on page 3-106 .
