Expanding the Local Storage of LogLogic EVA

You can expand the local storage of your existing LogLogic EVA instance by attaching more storage volumes during or after deployment.

This feature is applicable to the following platforms:
  • VMware ESXi
  • Amazon Web Services (AWS)
  • Microsoft Azure
By default, the feature to expand local storage is disabled in LogLogic EVA. While deploying LogLogic EVA, if you selected a machine type that has multiple storage disks, or if you want to further expand the local storage after deployment, then you must enable the storage growth feature in LogLogic EVA. Otherwise, you can see and use only the primary disk through LogLogic EVA, and not the additional disks.
  • While deploying LogLogic EVA, if you selected a machine type that has multiple storage disks, then you must enable the feature and then reboot the system.
  • To attach more local storage to an existing LogLogic EVA instance after deployment, then you must enable the feature, attach additional storage, and then reboot the system.
Note: The disk size for expanding the local storage must be more than 64 GB. If you select storage of less than or equal to 64 GB, it is not recognized during system boot and is not attached to the LogLogic EVA instance.

Prerequisites

Check if the feature is enabled in your system by running the following command: 
> system storage_growth status

Procedure

  1. If the feature is disabled, enable it by running the following CLI command: 
    > system storage_growth enable
    For details about the command, see the system Command section in TIBCO LogLogic® Log Management Intelligence Administration.
  2. Power off the LogLogic EVA instance.
  3. To attach more storage volumes to LogLogic EVA, follow the procedure applicable to the platform on which LogLogic EVA is deployed. For detailed steps, see the documentation of the corresponding platform.
    Note: While deploying LogLogic EVA, if you selected a machine type that has multiple storage disks, then skip this step and proceed to Step 4.
  4. Power on the LogLogic EVA instance.

What to do next

Verify that the total value of the internal storage has increased:
From the GUI Dashboards > System Status page
From the CLI Run the following command: 
> df -h
