To update the AlphaServer GS80/160/320 firmware with the LFU utility,
follow these steps:
1. At the console for each partition, shut down the operating system.
2. At the master SCM, turn power off to the system:
SCM_E0> power off
You can turn power off to individual partitions if you want. Ensure that
power is turned off to all partitions.
SCM_E0> power off -par 0
SCM_E0> power off -par 1
3. Use the show nvr SCM command to display SCM environment
variables. Record the hp_count and hp_qbb_maskn environment
variables as a record of the hardware partition configuration. You do
not change the hp_qbb_maskn environment variables, but record the
variables anyway.
SCM_E0> show nvr
COM1_PRINT_EN 1
HP_COUNT 2
HP_QBB_MASK0 3
HP_QBB_MASK1 c
HP_QBB_MASK2 0
HP_QBB_MASK3 0
HP_QBB_MASK4 0
HP_QBB_MASK5 0
HP_QBB_MASK6 0
HP_QBB_MASK7 0

4. Remove all hardware partitions:
SCM_E0> set hp_count 0
____________________ Note _____________________
You do not need to zero the hp_qbb_maskn environment
variables, only the hp_count.
