Setting Change After Configuring The N+M Cold Standby - Hitachi Compute Blade 2000 User Manual

Setting change after configuring the
N+M cold standby
(1) Partitions in Basic mode
When you change the EFI settings using the BMC' server blade Web console
after configuring the N+M cold standby, the new EFI settings take effect the next
time the EFI starts. If N+M switching occurs before the new settings are applied,
the system will switch over according to the EFI settings from the previous EFI
start.
(2) Partitions in LP mode
If you change the LPAR configuration (processors, memory, or device
assignment) after configuring the N+M cold standby, make sure that you press
F9: Save Configuration on the LPAR manager Menu screen. If not, the LPAR
manager configuration information in the management module differs from the
actual LPAR manager settings and N+M switching may fail.
Changing CNA after configuring the
N+M cold standby
If restoring iSCSI is required after CNA is changed in the configuration where
CNA is used with iSCSI for Personality, you need to configure the following
settings depending on the N+M cold standby.
Active server blade not
