automatically committed.
During an automatic code upgrade, each node of a working pair is upgraded sequentially. The
node that is being upgraded is temporarily unavailable and all I/O operations to that node
fails. As a result, the I/O error counts increase and the failed I/O operations are directed to the
partner node of the working pair. Applications do not see any I/O failures. When new nodes
are added to the system, the upgrade package is automatically downloaded to the new nodes
from the IBM Flex System V7000 Storage Node.

The upgrade can normally be performed concurrently with normal user I/O operations.
However, there is a possibility that performance could be impacted. If any restrictions apply to
the operations that can be performed during the upgrade, these restrictions are documented
on the Flex System V7000 Storage Node website that you use to download the upgrade
packages. During the upgrade procedure, the majority of configuration commands are not
available.

This automatic procedure provides a unified mechanism to upgrade the entire system in a
coordinated process with no user intervention. Excluding drives, when a node is rebooted as
part of the clustered system upgrade, the system checks that it is at the correct level. When
the system detects that the hardware is not running at the expected level, the system applies
the correct firmware.

Upgrading the software manually
During an automatic upgrade procedure, the Flex System V7000 Storage Node clustered
system upgrades each of the nodes systematically. The automatic method is the preferred
procedure for upgrading software on nodes; however, to provide more flexibility in the
upgrade process, you can also upgrade each node manually.
