This command displays the history of changes to the support and node serial numbers. The node serial number and the support serial number of an ONTAP system are generally the same and do not change over time. However, when capacity pools licensing is used, the support serial number is that of the capacity pool license serial number and the node serial number is generated by the license manager. Also, when a cluster is upgraded or converted from capacity tiers licensing to capacity pools licensing, its support serial numbers as well as its node serial numbers change.

Parameters

{ [-fields <fieldname>,…]: If you specify the -fields <fieldname>, … parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.
| [-instance ] }: If you specify the -instance parameter, the command displays detailed information about all fields.
[-seqnum <Sequence Number>] - Sequence number: Event sequence number
[-node {<nodename>|local}] - Node: Selects the node names that match this parameter value.
[-date <MM/DD/YYYY HH:MM:SS>] - Date: Selects the dates of serial number changes that match this parameter value.
[-reason <text>] - Reason for change: Reasons for serial number changes.
[-support-serial-number <text>] - Support Serial Number: Selects the support serial numbers that match this parameter value.
[-node-serial-number <text>] - Node Serial Number: Selects the node serial number that match this parameter value.

Examples

The following example displays the serial number change history of a four node capacity pools cluster. Its two HA pairs were originally assigned to capacity pools 390000101 and 390000102, and then both were reassigned to another capacity pool 390000103:
