lun
This table contains LUN-level SAN counters which are shared between 7-mode and C-mode. These counters are available for every mapped logical unit. The alias name for lun:node is lun_node.
Classic Object: lun
Table Row IDs
ID Format | Aggregation Type | Comment |
---|---|---|
{svm.name}:{instance_name}:{instance_uuid} |
(not applicable) |
This represents the construction of the row ID field, which is a single unique string that identifies a row. |
{node.name}:{svm.name}:{instance_name}:{instance_uuid} |
constituent |
This represents the construction of a row ID field for a row from a single node. |
{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. |
