2.1 Online Upgrade Considerations

This feature allows the upgrade of the InForm OS concurrently with I/O activity on the

attached hosts, provided certain conditions are met. For further information and pre-planning

Rolling Upgrades, refer to the latest version of the InForm OS Upgrade Pre-Planning Guide,

320-200158.

NOTE: Installing this Maintenance Update (MU) will likely disconnect the

management interfaces, thereby ending the CLI and InForm Management

Console (IMC) sessions and possibly generating alerts. This is expected behavior. If

the management interfaces are disconnected, reconnect and start new CLI or IMC

sessions.
