# Usage:
|
||||
# xcatchroot -h
|
||||
# xcatchroot [-v] -i osimage cmd_string
|
||||
#
|
||||
#
|
||||
# WARNING:
|
||||
# Be very careful when using this script!!! Make sure you are
|
||||
# very clear about exactly what you are changing and what effect
|
||||
# it will have.
|
||||
#
|
||||
# As a precaution it is advisable to make a copy of the original
|
||||
# spot in case your changes wind up corrupting the image.
|
||||
#
|
||||
# Note:
|
||||
# There is a fix for the AIX bosboot command that is needed for
|
||||
# this script to work properly if your command involves modifying
|
||||
# the ODM. The AIX APAR information is not available at this time.
|
||||
#
|
||||
# However, it is very easy to check for and/or make the required
|
||||
# modification.
|
||||
#
|
||||
# In the bosboot code, there is a check for the creation of a boot
|
||||
# image; if the image creation is anything other than disk, the
|
||||
# odm values are not picked up. You will have to confirm that
|
||||
# the bosboot command in your spot has the check removed.
|
||||
#
|
||||
# Edit the bosboot command contained in the spot (save a backup).
|
||||
# (ex. "vi <path_to_spotName>/usr/sbin/bosboot"). Search for
|
||||
# "zap it as". The next line checks to see if the
|
||||
# device prefix is "hdisk". Comment out the line and the
|
||||
# corresponding "fi" which ends the "if" statement. Now this
|
||||
# code will always execute. Save changes.
|
||||
#
|
||||
# Note: Always run the NIM check operation after you are done updating
|
||||
# your spot.
|
||||
#
|
||||
# nim -Fo check spotName
