Classic Object: volume

Table Row IDs

ID Format Aggregation Type Comment

This represents the construction of the row ID field, which is a single unique string that identifies a row.

{node.name}:{node.uuid}

node

This represents the construction of the row ID field in node combo object, which is a single unique string that identifies a row.

{svm.name}:{svm.uuid}

svm

This represents the construction of the row ID field in svm combo object, which is a single unique string that identifies a row.
