Configure to boot from a SAN-attached disk by using AIX to copy the current root volume group onto a LUN.
- If you install the Oracle FS Path Manager (FSPM) on the system before cloning the current boot LUN onto a Oracle FS System LUN, FSPM is installed and running when you boot from the LUN.
- If you clone a system that does not have FSPM installed, then install FSPM on the new boot LUN after booting from it.
- In the Oracle FS System Manager (GUI), create a LUN and map it to the system.
- If FSPM is not installed on the system, ensure that there is only a single path connected between the host and the new LUN.
- Enter the cfgmgr command and verify the LUN is visible to the system.
- Run the following command:
smit alt_clone
Note: If smit does not have the alt_clone shortcut, you must load the bos.alt_disk_install.rte fileset from the AIX installation CD.
- In the template, enter the target disk to install.
Most of the remaining fields should stay at their default values, but you may want to change the following settings (optional):
- Verbose Output
- Reboot when Complete
- Set bootlist to boot from this disk on next reboot
Refer to the AIX documentation for more information.
- Press Return to begin the copy process.
After the copy finishes, you can boot from the destination LUN. When you are ready to boot from the new LUN, use the bootlist command to make sure that the LUN comes first in the list, and then reboot the system. Additional information on AIX bootlist is provided in this document.
