3. In Figure 3-74, you can see the result of executing alt_disk_install on our test AIX 5L
V6.1 system.

Considerations: If the rootvg is mirrored, remove the second copy before running the
alt_disk_install command, or alternatively, use the other mirroring method, which is
described in 3.10.3, “New installation process for SAN Boot” on page 185.
4. The alt_disk_install command can run for several minutes. It creates a new volume
group on the storage subsystem disk called altinst_rootvg and creates and copies all
logical volumes from rootvg. You can verify the result with the lspv command, activating
the volume group with varyonvg altinst_rootvg and lsvg -l altinst_rootvg
commands as shown in Figure 3-75.
