3.10.2 Registering the HDLM Script for HACMP
To use HACMP, you need to add custom disk methods to the HDLM script for

procedure assumes that HACMP5.4 is used. The actual screen transitions for the SMIT
menu might be different depending on the HACMP version. Therefore, also refer to
the HACMP documentation.
To specify a custom disk method:
