Increase a virtual machine's hard disk

-

To increase a virtual machine's hard disk using VMware vRealize Automation (vRA) and vRealize Orchestrator (vRO), you can follow these general steps:

  1. Create a vRO Workflow: Develop a workflow in vRO that performs the disk expansion. This workflow should include:

    • Identifying the target virtual machine.
    • Locating the specific hard disk to be expanded.
    • Executing the disk size modification.
    • Rescanning the storage adapter to recognize the new disk size.
    • Extending the filesystem within the guest OS to utilize the additional space.
Kindly please refer the below vRO workflow screen shots:


var devices = vm.config.hardware.device;

//var match = diskInfo.match(/\w+\s+\w+\s+(\d+)\s+.+?:\s*(\d+)\s*GB/);

var totalsize = increaseSizeGB + Number(Size)

var newDiskSizeKb = totalsize * 1024 * 1024;

//var diskName = 'Hard disk ' + match[1];

 

configSpec = new VcVirtualMachineConfigSpec();

configSpec.changeVersion = vm.config.changeVersion;

for (i in devices){

    if (devices[i].deviceInfo.label == disknames.toString()){

        var disk = devices[i]

        System.debug("Found '" + disk.deviceInfo.label + "'");

    }

}

var deviceChanges = new Array();

var deviceChange = new VcVirtualDeviceConfigSpec();

deviceChange.operation = VcVirtualDeviceConfigSpecOperation.edit;

deviceChange.device = disk;

deviceChange.device.capacityInKB = newDiskSizeKb;

deviceChanges.push(deviceChange);

configSpec.deviceChange = deviceChanges

//var actionResult = new Array();

//actionResult.push(configSpec);

task = vm.reconfigVM_Task(configSpec);



Create a vRO action for returnharddisknames


var disknames = new Array();

var devices = vm.config.hardware.device;

for (i in devices){

var disk = devices[i]

     if(disk.deviceInfo.label.indexOf("Hard disk") == "0"){

        System.log("----"+devices[i].deviceInfo.label.indexOf("Hard disk"));

        System.log("----"+devices[i].deviceInfo.label);

        disknames.push(String(disk.deviceInfo.label));

    }

}

return disknames;



Create a vRO action for returnharddisksize


if(diskString != ""){

    var disknames = new Array();

    var devices = vm.config.hardware.device;

    for (i in devices){

        if (devices[i].deviceInfo.label == diskString){

            var disk = devices[i]

                    return String((disk.capacityInKB / 1024 / 1024));

        }

    }

}

return "";

Creating Snapshots for Unmanaged VMs in Aria Automation (vRealize Automation)

-
Image
 In multi-tenant environments powered by Aria Automation (vRealize Automation) , it's common for tenants to occasionally request snapshots for unmanaged virtual machines (VMs) . These unmanaged VMs exist in vCenter but are not provisioned through vRA and therefore fall outside the standard automation lifecycle. To address this need without impacting the broader environment or other tenants, we implemented a dedicated catalog item that allows tenants to safely request snapshots for their unmanaged VMs— securely, in isolation, and with auditability . Here’s how we approached this solution using a custom workflow and catalog configuration in Aria Automation. The Challenge Tenants may operate legacy or externally imported VMs that are not managed via vRA’s provisioning engine. Creating snapshots for these VMs traditionally requires manual intervention from infrastructure teams, which: Increases support overhead Introduces potential human errors Offers ...

Bulk import security policies into Palo Alto Networks firewalls

To bulk import security policies into Palo Alto Networks firewalls, you'll typically need to leverage the Palo Alto API or CLI with a script. I am using an Excel file (XLS), IP address validation, and mapping source and destination zones, for comprehensive solution to automate the process. 1. Input from XLSX File : You will first need to read the data from the XLS file. 2. Check for Existing Rules : Before creating new rules, you should check if similar rules already exist on the firewall. This could be done by comparing the rule names, source, and destination IPs, and zones. 3. Mapping Source Zone and Destination Zone : Ensure that the source and destination zones are correctly mapped according to your firewall configuration. 4. IP Address Validation : Before adding a rule, you'll need to validate that the IP addresses specified in the file are valid 📝  Flow Diagram  (Text Representation) Further Automation If you need enhancements or additional automation features , fee...

Automating Tag Creation & Assignment to VMs with vRA + vRO

-
Image
  Use Case Summary A user provisions a VM from vRA. Once the VM is deployed in vCenter , a vRO workflow is triggered via Event Broker subscription. The workflow: Checks if the Tag exists (using REST API to NSX-T). If not found, creates the Tag under the correct category. Assigns the Tag to the newly provisioned VM. This eliminates the need for manual intervention and ensures every VM is tagged correctly for policies, automation, and visibility . High-Level Flow VM Provisioning in vRA User requests VM with required details (e.g., Environment, Owner, Application). Event Broker Subscription After provisioning, vRA triggers a vRO workflow . vRO Workflow Actions Connects to vCenter using REST API. Checks if Tag exists. If exists → Skip creation. If not exists → Create new Tag under category. Assigns Tag to the VM. Result VM is provisioned with the right tags automatically applied . Flow Diagram Steps Start VM Prov...
