The following document describes the alt-disk-install procedure to perform an AIX operating system update from AIX 5200-ML2 to AIX 5200-ML5. This procedure is used to migrate from the existing IBM Power4 architecture running the EGATE Production environment on S85 machines, to the new IBM Power5 architecture running on the p590 machines. This procedure is required because EGATE requires AIX 5.2 and will not run on AIX 5.3. The lowest version of AIX that will run on the p590 Power5 architecture is AIX 5200-05 and EGATE is currently running on AIX 5200-02.
This procedure creates a "mksysb" of the current mdctxudb85 production EGATE rootvg, installs this "mksysb" using the "alt-disk-install" method, and updates the "alt-disk" to AIX 5200-05.
This procedure is documented as a specific example of updating the EGATE production machine "mdcapega01" using "mdcapega01" as the p590 partition. It is assumed the "mdcapega01" partition is configured and running AIX 5.2 ML5 on the p590 and a disk is available to perform an alt-disk-install.
Perform a mksysb of the existing pre-production EGATE system to the NIM server:
mdcapnim01: exportfs -i -o 'root=*' /export/mksysb
mdcapnim01: exportfs -i -o 'root=*' /export/lpp_source
mdctxudb85: mkdir /mnt/mksysb
mdctxudb85: mount mdcapnim01:/export/mksysb /mnt/mksysb
mdctxudb85: mksysb -Xive /mnt/mksysb/mdctxudb85.mksysb
mdctxudb85: umount /mnt/mksysb
Mount the "mksysb" filesystem from the NIM server to the new p590 partition under /mnt/mksysb. Mount the "lpp_source" filesystem from the NIM server to the new p590 partition under /mnt/lpp_source:
mdcapega01: showmount -e mdcapnim01
mdcapega01: mount mdcapnim01:/export/mksysb /mnt/mksysb
mdcapega01: mount mdcapnim01:/export/lpp_source /mnt/lpp_source
Perform a PHASE 1 ONLY alt-disk-install of the mksysb on the p590 partition.

Before proceding, remove any locked eFixes that may prevent the "alt-clone" process from executing successfully. Remove the following files:
mdcapega01: rm /alt_inst/usr/emgrdata/DBS/efix.db
mdcapega01: rm /alt_inst/usr/emgrdata/DBS/files.db
mdcapega01: rm /alt_inst/usr/emgrdata/DBS/pkglck.db
Perform a PHASE 2 ONLY alt-clone install and do an "update_all" for all AIX 5.2 filesets installed on the alt-disk. Use the lpp_source "/mnt/lpp_source/5.2AllCurrent/installp/ppc" and add the keyword "update_all" to the line that says "Bundle to install":
mdcapega01: smitty alt_install

When phase 3 completes, all filesystem associated with the altinst_rootvg should be automatically unmounted and the altinst_rootvg volume group should be automatically varied off. Change the bootlist to boot from the newly built and updated alternate disk:
mdcapega01: bootlist -m normal hdisk1 hdisk0
mdcapega01: bootlist -m normal -o
Shutdown the partition and activate the partition from the HMC:
mdcapega01: shutdown -Fh
