Updating Kernel Packages and Applying OS Update
Packages
This section explains how to update a kernel package or apply an OS update
package on a host on which HDLM is installed.
You can also update a kernel package or apply an OS update package in
single user mode.
If you create an initial RAM disk image file for HDLM, specify a file name that
is supported by the kernel after the kernel is upgraded. In addition, if you
edit the boot loader configuration file, copy the startup settings of the SCSI
device that was added after the kernel update, and then change the definition
so that the OS starts in a state in which HDLM is configured.
The following table lists the sections you can refer to for procedures that
apply to different OSs and installation environments.
