You can find more information about the differences about each process by accessing the Information Center, searching for Installation topics using the following link: http://publib.boulder.ibm.com/infocenter/aix/v6r1/index.jsp?topic=/com.ibm.aix.bas eadmn/doc/ 2.13.2 Installing AIX 6.1 using a pre-existing installation Follow this procedure for installing AIX 6.1 using a pre-existing installation. Creating a boot disk with alt_disk_install The following procedure is based on the alt_disk_install command, cloning the operating system located on an internal SCSI disk to the storage subsystem SAN disk. Tip: In order to use the alt_disk_install command, the following file sets must be installed: ► bos.alt_disk_install.boot_images ► bos.alt_disk_install.rte (for rootvg cloning) It is necessary to have an AIX system up and running and installed on an existing SCSI disk. Otherwise, you must first install a basic AIX operating system on the internal SCSI disk and then follow this procedure: 1. Create a logical drive on the storage subsystem, big enough to contain all rootvg data, and make the appropriate zoning to see the storage subsystem from the AIX system. 2. Assuming that the source internal SCSI disk is hdisk0 and the target disk on the storage subsystem is hdisk3, you can use one of the following commands to clone hdisk0 to hdisk3: /usr/sbin/alt_disk_install –C –B -P all hdisk3 /usr/sbin/alt_disk_copy -O -B -d hdisk3 /AIX 6.1/ smitty alt_clone /appropriate input required/ Attention: The target disk must have the same or greater capacity than the source disk. 104 SAN Boot Implementation and Best Practices Guide for IBM System Storage
3. Figure 2-126 shows the result of executing alt_disk_install on our test IBM AIX 5L V6.1 system. Figure 2-126 Executing alt_disk_install Consideration: 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 2.13.3, “New Installation process for SAN Boot” on page 107. 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 it 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. See Figure 2-127.
