To prepare to upgrade SFCFS on an alternate disk

1. Make sure that the SFCFS installation media is available.

2. On the nodes that you want to upgrade SFCFS, create an alternate boot disk identical to the primary boot disk with the same size and partitions as the primary boot disk.

3. Check the status of the physical disks on your system.

   Note:

   The alternate disk must have a physical identifier and must not contain any mounted volume groups.

   # lspv
   Output similar to the following displays:
   hdisk0         0009710fa9c79877    rootvg   	active
   hdisk1         0009710f0b90db93    None

   If the alternate disk does not have a physical identifier, set the physical identifier for the disk:

   # chdev -l hdisk1 -a pv=yes

4. Make sure that the following filesets are installed on the primary disk: bos.alt_disk_install.boot_images, bos.alt_disk.install.rte

5. Mount the SFCFS installation media.

   Determine the filesets you want to install on the alternate disk by running the following command:

   # ./installsfcfs -install_option

   where install_option is one of the following:

   -minpkgs: For installing the minimum set of packages

   -recpkgs: For installing the recommended packages

   -allpkgs: For installing all packages

   Copy the required filesets to a directory on the primary boot disk, for example /usr

   If you are upgrading the operating system along with SFCFS, copy the necessary operating system filesets and the SFCFS filesets to a directory on the primary disk, for example /usr.
