Updating CMM Software

even if the failover configuration flag is marked "manual", if any of the above condition is met, automatic failover may occur.

23.9.1Setting Failover Configuration Flag

To set the value of the failover configuration flag, the following CLI command can be used:

cmmset -l cmm -d failoveronredundancy -v [manual/automatic]

Where:

Manual: Upon establishing redundancy between the two CMM’s, failover does NOT occur automatically to the CMM with the newer firmware version. This is the default value.

Automatic: Upon establishing redundancy, failover to the CMM with the newer firmware version occurs automatically.

23.9.2Retrieving the Failover Configuration Flag

To retrieve the value of the failover configuration flag, the following CLI command is used:

cmmget -l cmm -d failoveronredundancy

Where the return value will be: automatic, manual or an error

23.10Single CMM System

When updating CMMs in a system that only contains a single CMM, once the CMM enters the update mode, any components in that system that the CMM manages power to may power down because the CMM applications are stopped. Consult your system and board documentation to determine the effect of updating or removing the CMM from the system.

23.11Redundant CMM Systems

In systems with redundant CMMs, the update should be done first on the standby CMM. It is strongly recommended that an update is not performed on the active CMM.

Once the CMM enters the update mode, the chassis will lose redundancy for the duration of the update process. After the update is complete, initiate a failover from the active to the standby and update the second CMM which is now the standby.

Note: CMMs in a redundant system must only be updated one at a time, otherwise the chassis will become unmanaged.

23.12CLI Software Update Procedure

The CLI supports a command for an update request. The syntax of the command is as follows:

cmmset -l cmm -d update -v “[Update Package path and filename] [force]
