Description: When a blade management controller, switch or the MM is reset, the inventory data is refreshed in the MM database. This includes items like IBM VPD (e.g. - serial number, UUID) and MAC address information.
Applications need to know when this information has been populated on the MM before they begin to query it using SNMP or other means. This simple flag object will return a ready or notReady indication when all blades and switches have completed initialization and the inventory information has been provided to the MM.
Note that due to components that may be experiencing a 'communication failure' or 'initialization failure' condition, this object may continue to show notReady. Therefore, any application that polls this object should also incorporate a timeout
A more granular, per-blade status is available via the bladeSystemStatusTable
What is componentInventoryReady?
This flag reports notReady(0) or ready(1) to indicate whether the MM database's inventory data, including VPD like serial number and UUID and MAC address information, has finished repopulating after a blade controller, switch, or MM reset. An administrator or a monitoring application polls this flag to know when it's safe to start querying inventory data via SNMP, rather than reading incomplete or stale values immediately after a reset. For example, a management script waits until this flag reports ready(1) after rebooting the MM before it resumes automated inventory polling.
