How to Expand a Virtual Disk in VMware vSphere Virtual Machine with Ansible?
Ansible Expand a Virtual Disk in VMware vSphere Virtual Machine
- `community.vmware.vmware_guest_disk`
- Manage disks related to a virtual machine in a given vCenter infrastructure
Let's talk about the Ansible module `vmware_guest_disk`.
The full name is `community.vmware.vmware_guest_disk`, which means that is part of the collection of modules to interact with VMware, community-supported.
It manages disks related to a virtual machine in a given vCenter infrastructure.
Parameters
- hostname string / username string / password string / datacenter string / validate_certs boolean - connection details
- datacenter string - The datacenter name to which the virtual machine belongs to
- scsi_controller / unit_number / scsi_type string - SCSI controller details
- size / size_kb / size_mb / size_gb / size_tb string - Disk storage size
- disk_mode string - persistent / independent_persistent / independent_nonpersistent
The following parameters are useful in order to Expand a Virtual Disk in VMware vSphere Virtual Machine using the module `vmware_guest_disk`.
First of all, we need to establish the connection with VMware vSphere or VMware vCenter using a plethora self-explicative parameters: `hostname`, `username`, `password`, `datacenter`, and `validate_certs`.
Once the connection is successfully established you could specify the desired disk configuration, in this expansion, a disk is connected to a virtual machine.
The mandatory parameters are only `datacenter` and `unit_number`.
The `datacenter` parameter specifies which datacenter name the virtual machine belongs to, for resources allocations.
The disk must be connected to a SCSI controller inside the virtual machine, so you should specify all the small details like `scsi_controller`, `unit_number`, and `scsi_type`.
You might be interested in deep-diving into some performance analysis to properly adjust these parameters.
You could specify the disk size via various parameters according to the needed size unit: kb, MB, GB, TB, etc.
One most important parameter is the `disk_mode`, default to `persistent` mode, other options are `independent_persistent` and `independent_nonpersistent`.
