# Example config for PXE based on GRUB2 booting on PPC64/PPC64LE # (instead of PXE legacy that is not supported on PPC64/PPC64LE) # see https://github.com/rear/rear/pull/1339 # Default is to create Relax-and-Recover rescue media as ISO image # set OUTPUT to change that # set BACKUP to activate an automated (backup and) restore of your data. # Possible configuration values can be found in /usr/share/rear/conf/default.conf # SAN and multipath and boot over SAN specific part on PPC64/PPC64LE: # There is no direct link between multipath/boot-over-SAN and PXE (even on POWER). # Multipath is used in this example because PowerVM LPARs usually need multipath. # There is nothing special on PowerVM LPAR with single VIOS but that is not commonly used. # In contrast PowerVM LPAR with DUAL VIOS (HA configuration) needs multipath # for dual disk access (vscsi over 2 VIOS) or NPIV (Fiber Channel virtualization). # And NPIV (which is quite popular) needs also BOOT_OVER_SAN.
