Examples for configuring re-IPL

Typical examples include configuring re-IPL from an FCP device and specifying parameters for re-IPL.

  • To configure an FCP re-IPL device 0.0.5711 with a LUN 0x1711000000000000 and a WWPN 0x5005076303004715 with an additional kernel parameter noresume: 
    # echo 0.0.5711 > /sys/firmware/reipl/fcp/device
# echo 0x5005076303004715 > /sys/firmware/reipl/fcp/wwpn
# echo 0x1711000000000000 > /sys/firmware/reipl/fcp/lun
# echo 0 > /sys/firmware/reipl/fcp/bootprog
# echo 0 > /sys/firmware/reipl/fcp/br_lba
# echo fcp > /sys/firmware/reipl/reipl_type
  • To set up re-IPL from a CMS NSS:
    1. Set the reipl_type to nss: 
      # echo nss > /sys/firmware/reipl/reipl_type
    2. Set up the attributes in the nss directory: 
      # echo CMSNSS > /sys/firmware/reipl/reipl_type/nss/name
# echo "AUTOCR" > /sys/firmware/reipl/reipl_type/nss/parm
