Splitting the System
Splitting an NEC Express5800/ft series system divides it into two independently-functioning
systems: the Production Side, which continues to run your applications, and the Upgrade Side,
which you can safely upgrade.
Splitting the system:
•
Disables RDR mirroring between the internal disks in each CPU/IO module enclosure
•
Detach the Upgrade Side from system resources such as the network, any user-specific
application data disks, and any external PCI resources (such as an external storage).
•
Disables any user-specified applications and services on the Upgrade Side so they cannot
restart if you restart the operating system on the Upgrade Side.
•
Queues any ActiveService Network alerts generated on the Upgrade Side until the system is
merged.
You can split a system only if it meets the prerequisites for the Active Upgrade process and has
passed the readiness check.
IMPORTANT:
1.
When in split mode, the Upgrade Side has no access to the network; the Upgrade Side can
only access to the Production Side. If you need a network resource to obtain any software
installation packages you intend to run, transfer the software to the system
before
you
initiate split mode. Furthermore, put the software on one of the system disks, as these are
the only disks you can access on the Upgrade Side while the system is in split mode.
2.
Split the system only when you are sitting at the console for your NEC Express5800/ft
series system. The Active Upgrade Console is not supported over remote connections.
CAUTION:
Do not perform any hardware maintenance, including the removal of either CPU/IO module,
after you have initiated the Active Upgrade process (by clicking Split).
