Hi,
Thank you both of you for your kind suggestions.
We are using leap-upgrade tool to upgrade. In upgrade there is no issue. We
have a health checkup also post upgrade.
The issue is in VMware but not sure when creating manually the “*Snapshot
the virtual machine memory*” is set to Yes but when I am creating the
snapshot through ansible automatically it is setting as No. This is
something with VMware maybe..
- Name: Create VM snapshot
Uri:
URL: https://api.xyz/virtualization/snapshot/snow
User: “ {{ snapshot_user }}”
Password: “{{ snapshot_Password }}“
force_basic_auth: true
Method: post
Body_format: json
Body: |-
{
“Hostname”: “{{ vm_hostname }}”,
“Task”: “ create”,
“Snapshot_name”: “upgrade-{{vm_hostname}} “
}
Status code: 202
Register: snapshot_result
Regards
PD
