|
|
# This is a program to save the xCAT tables to the /install/xcatmigrate directory;
|
|
# then close and export the /install LVM
|
|
#
|
|
# The reverse process on the other system can be done if the LVM disks are
|
|
# writeable and online. The zxcatmigrate script can be used for that.
|
|
# It will issue pvscan, vgimport, vgchange -ay, mkdir, then mount commands.
