You can configure to boot from a SAN-attached disk by installing AIX from operating system media onto a LUN. (This is sometimes referred to as performing a clean installation. A clean installation is where you install the operating system for the first time and not overwrite or upgrade an existing version.)
Perform this procedure while installing the AIX operating system from an operating system media.
- In the Oracle FS System Manager, create a LUN and map it to the system.
- Enter the cfgmgr command and verify that the LUN is visible to the system.
- Use the lspv command to list the physical volumes and note the volume IDs.
- Stop AIX.
- Verify that there is only one path to the Oracle FS System by techniques including masking ports at theOracle FS System, switch zoning, or removing the Fibre Channel connections. For information on these techniques, review the Oracle Flash Storage System Administrator’s Guide.
Important! There must be exactly one path to the new boot LUN. If you boot from the LUN when there is more than one path to the boot LUN, some configuration commands might fail.
- Begin the AIX installation from the operating system media. Change the installation destination to the Oracle FS System LUN, and follow the prompts to install AIX.
- Reboot AIX.
Note: If the system boots from the internal drive, alter the bootlist to boot from the new
LUN. See
AIX Bootlist Considerations for details.
- Install any necessary AIX patches. For patch information, refer to the IBM Web site (http://www.ibm.com/support/fixcentral).
- Install Oracle FS Path Manager software.
