Hitachi Compute Blade 2000 User Manual page 1574

The N+M cold standby can be set over multiple systems.
The active and standby partitions need not exist in the
same system.
Only a partition with the same configuration as the

active partition and with the LPAR manager license
enabled is available for the standby partition to the
active partition with the LPAR manager license
enabled.
When a standby partition is shared by the active

partitions in Basic mode and LPAR manager mode,
configure the standby partition using the model with
LPAR manager that can be used in both Basic mode
and LPAR manager mode.
Implementing the N+M cold standby would require

separate installation of ServerConductor/Blade Server
Manager Plus. For details, contact the reseller from
which you purchased this product.
When you use the teaming function provided by Intel

PROSet on the server blade, it is necessary to
prepare the N+1 Teaming Kit additionally. For details,
contact the reseller from which you purchased this
product.
Different Smart Configure methods are allowed for the

active and standby partitions.
When recovering N+M cold standby, make sure that an
operating mode (LP mode or Basic mode) for the standby
server blade is the same as that for the active server blade
at N+M group registry. When changing the operating mode
for the standby server blade after N+M failover is executed,
make sure that the operating mode is returned to the
original mode before recovering N+M cold standby. If you
try to recover N+M cold standby with the standby server
blade having the changed operating mode, the following
may occur.
LPAR manager configuration may not be

recovered correctly.
Recovering N+M cold standby may fail.
