To accommodate flexible deployment scenarios, the following guidelines provide information about the required sizes of partitions based on the number of devices and interfaces.

* The amount of storage required to maintain historical data using default Data Retention settings.

Setting up Partition Sizes

The Storage Capacity column of the table contains the total recommended HDD size of the VM. By default, when the NetMRI VM is first set up, the HDD is divided into smaller partitions using 80 GB. For more information, see VM Partitioning Guidelines.

Note

Any available storage remains unused until you assign it. To resize the partitions to match the table above, use the provisiondisk CLI command.

Adding Additional Space to the Partition

To add additional space to the partition, follow the steps below:

Add additional HDD to the NetMRI VM.
Reboot the NetMRI VM.
In the administrative shell, run the provisiondisk command.

Migrating from a Physical Appliance to a Virtual Machine

Follow the steps below to migrate from a physical appliance to a virtual machine (VM):

Upload the hotfix physical-to-vm-assistance.gpg on the physical appliance.
Run the script using the diag command.
Copy the script's output to a notepad or another suitable location. The script output provides the recommended partition sizes. When setting up the VM, you will require the recommended partition sizes.
Set up the VM using the latest image from NetMRI.
Create the additional HDD with the recommended space (based on the diag script output noted above) and attach it to the VM using NetMRI.
Reboot the NetMRI VM.
Log in to the admin CLI. The default username is “admin” and the default password is “admin”.
Using the provisiondisk command, expand the size of each partition in accordance with the diag script output noted above.
Create a database backup on the hardware appliance.
Restore the database from the backup to the VM appliance.
