Hi;
I'm trying to automate the addition of disk devices to VM guests. After a
bit of work and lots of lessons learned, I've gotten to this point:
- name: add disk space
vmware_guest_disk:
hostname: "{{s}}"
username: "{{vu}}"
password: "{{vp}}"
datacenter: "{{dc}}"
validate_certs: no
name: "{{inventory_hostname}}"
disk:
- size_gb: 20
type: thick
datastore: "{{dsi.datastores[0].datastore_cluster}}"
scsi_controller: 0
state: present
delegate_to: localhost
when:
- dsi.datastores[0].datastore_cluster|length > 0
- dsi.datastores[0].freeSpace / dsi.datastores[0].capacity * 100 > 20
This results in:
TASK [add disk space]
***************************************************************************************************
fatal: [cl1vinfspt1000 -> localhost]: FAILED! => {"changed": false, "msg":
"Please
specify 'unit_number' under disk parameter
at index [0], which is required while creating disk."}
The number of disks on the vms which need disk additions is going to vary -
in fact, some may even have multiple controllers. I've used govc to add
disks to vms and it just tacks the disk on the end of the bus.
So, two questions:
- Is there a way to tell vmware_guest_disk to use the next available
unit number?
- Failing that, is there a clever way to identify the next available
scsi unit number? I'm even willing to use OS commands and create a
variable... interesting thought, that. I'll look there next.
Thanks for any hints/tips/suggestions.
