over the task by being able to perform each phase in isolation from the others. It
is not required to perform them all at once.
The three phases of the alternate disk install are:
1. Phase 1
• Create the altinst_rootvg, logical volumes and file systems.
• Restore or copy files to the /alt_inst file systems.
2. Phase 2
• Copy a resolv.conf file to the /alt_inst/etc file system if specified.
• Copy NIM client configuration information if specified.
• For clones, install any new filesets, updates, and fixes.
• Run any user specified customization script.
3. Phase 3
• Manipulate the ODM databases and /etc/filesystems file.
• Build the boot image.
• Unmount the /alt_inst file systems and rename the logical volumes and file
systems.
Phase two can be performed with phase one or phase three and can also be
performed on its own multiple times if required before phase three is run.
The phases performed are controlled by the new -P option that has possible
values as shown in Table 22.

The target disk name is required for all phases, even though the altinst_rootvg
has already been created.
Some standard alt_disk_install options, such as the reboot option and the no
bootlist option, are not allowed in phase one or phase two.
Specifying an exclude list (-e exclude_list) is not allowed in phase two or phase
three.
If a flag is used in a wrong phase, a warning is displayed, but the install does not
terminate.
