Thank you, that has helped alot.
I was looking at the max option:
- name: debug - show max lun number
debug:
msg: "{{item.lun.lun}}"
loop: "{{luns.json.data}}"
when: "{{item.lun.lun | max}}"
But it returns the following:
TASK [debug - show max lun number]
****************************************************************************************************************************************
fatal: [127.0.0.1]: FAILED! => {"msg": "The conditional check
'{{item.lun.lun | max}}' failed. The error was: Unexpected templating type
error occurred on ({{item.lun.lun | max}}): 'int' object is not
iterable\n\nThe error appears to be in
'/home/nbritton/ansible/gts-core-storage-operations/hds/get_luninfo.yml':
line 65, column 5, but may\nbe elsewhere in the file depending on the exact
syntax problem.\n\nThe offending line appears to be:\n\n\n - name: debug -
show max lun number\n ^ here\n"}
The value i am after is the last one in the output here:
TASK [debug new vars]
*****************************************************************************************************************************************************
ok: [127.0.0.1] => {
"msg": "am1vmhost12,CL8-B,15,83,SFTP,6"
}
