Hello, Basically want to add the items of net\_interface into aggregate\_info or create new list/dictionary based on key value of node\_name. Looking for assistance on how i can achieve this please and thank you. Outcome of what want it listed below. **list called: aggregate\_info** { “name”: “agg\_Data1\_Cluster01”, “node\_name”: “TEST\_NA\_CLUSTER\_01-01”, “percent\_used\_capacity”: “46”, “size\_available”: 8141263818752, “size\_avaliable\_80%”: 5122753242726, “size\_total”: 15092552880128, “size\_total\_80%”: 12074042304102, “size\_used”: 6951289061376 }, { “name”: “agg\_Data1\_Cluster02”, “node\_name”: “TEST\_NA\_CLUSTER\_01-02”, “percent\_used\_capacity”: “34”, “size\_available”: 5116275568640, “size\_avaliable\_80%”: 3561215869747, “size\_total”: 7775298494464, “size\_total\_80%”: 6220238795571, “size\_used”: 2659022925824 } **list called: net\_interface** { “address”: “XX.XXX.X.XXX”, “address4oct”: “224”, “data\_protcol”: “none”, “failover\_group”: “Management”, “node\_name”: “TEST\_NA\_CLUSTER\_01-01”, “role”: “node\_mgmt”, “vserver”: “TEST\_NA\_CLUSTER\_01” }, { “address”: “XX.XXX.X.XXX”, “address4oct”: “226”, “data\_protcol”: “none”, “failover\_group”: “Management”, “node\_name”: “IQ-REG\_NA\_CLUSTER\_01-02”, “role”: “node\_mgmt”, “vserver”: “TEST\_NA\_CLUSTER\_01” } **Out Come want:** Dictionary called: aggregate\_info (original) or new name { “name”: “agg\_Data1\_Cluster01”, “node\_name”: “TEST\_NA\_CLUSTER\_01-01”, “percent\_used\_capacity”: “46”, “size\_available”: 8141263818752, “size\_avaliable\_80%”: 5122753242726, “size\_total”: 15092552880128, “size\_total\_80%”: 12074042304102, “size\_used”: 6951289061376 “address”: “XX.XXX.X.XXX”, “address4oct”: “224”, “data\_protcol”: “none”, “failover\_group”: “Management”, “role”: “node\_mgmt”, “vserver”: “TEST\_NA\_CLUSTER\_01” }, { “name”: “agg\_Data1\_Cluster02”, “node\_name”: “TEST\_NA\_CLUSTER\_01-02”, “percent\_used\_capacity”: “34”, “size\_available”: 5116275568640, “size\_avaliable\_80%”: 3561215869747, “size\_total”: 7775298494464, “size\_total\_80%”: 6220238795571, “size\_used”: 2659022925824 “address”: “XX.XXX.X.XXX”, “address4oct”: “226”, “data\_protcol”: “none”, “failover\_group”: “Management”, “role”: “node\_mgmt”, “vserver”: “TEST\_NA\_CLUSTER\_01” } ---

Adding further to above, i know i can get the value i want by doing this. - debug: msg: “{% for address in net\_interface if address.node\_name == ‘IQ-REG\_NA\_CLUSTER\_01-01’ %}{{ address.address }}{% endfor %}” Anyway to add that logic when creating the aggregate\_info list. for example, but when trying to do this i get a template error. Don’t know if its possible to do or i am missing something with my syntax. - name: Get\_Aggregate\_Info #no\_log: True set\_fact: aggregate\_info: “{{ aggregate\_info | d() + [ { ‘name’: item.value.aggregate\_name, ‘size\_available’: item.value.aggr\_space\_attributes.size\_available | int, ‘size\_avaliable\_80%’: (((item.value.aggr\_space\_attributes.size\_total | int) \* 0.8) - (item.value.aggr\_space\_attributes.size\_used | int)) | round | int, ‘size\_total’: item.value.aggr\_space\_attributes.size\_total | int, ‘size\_total\_80%’: ((item.value.aggr\_space\_attributes.size\_total | int) \* 0.8 ) | round | int, ‘size\_used’: item.value.aggr\_space\_attributes.size\_used | int, ‘node\_name’: item.value.nodes.node\_name, ‘percent\_used\_capacity’: item.value.aggr\_space\_attributes.percent\_used\_capacity ‘test’: {% for address in net\_interface if address.node\_name == item.value.nodes.node\_name %}{{ address.address }}{% endfor %} } ] }}” with\_items: “{{ netapp\_info.ontap\_info.aggregate\_info | dict2items }}” when: - (‘agg\_’ in item.value.aggregate\_name) ---

Figured out how to merge the lists based on values in each list. - name: merge lists set\_fact: merged\_list: “{{ merged\_list|default() + [{ ‘name’: item[0].name, ‘size\_available’: item[0].size\_available, ‘size\_avaliable\_80’: item[0].size\_avaliable\_80, ‘size\_total’: item[0].size\_total, ‘size\_total\_80’: item[0].size\_total\_80, ‘size\_used’: item[0].size\_used, ‘node\_name’: item[0].node\_name, ‘percent\_used\_capacity’: item[0].percent\_used\_capacity, ‘current\_node’: item[1].current\_node, ‘address’: item[1].address, ‘address4oct’: item[1].address4oct, ‘failover\_group’: item[1].failover\_group, ‘data\_protcol’: item[1].data\_protcol| default(‘’), ‘role’: item[1].role, ‘vserver’: item[1].vserver }] }}” when: “item[0].node\_name == item[1].current\_node” loop: “{{ query(‘nested’, aggregate\_info, net\_interface) }}”
