Execute the following procedure to restore the VM(s) on the DSC SWe - vSP2000 Platform. After a successful VM restore, the Web UI is used to verify the slot status and to ensure all applications are running. 

Note

It is recommended that you perform the complete VM restore for the Routing and Management VM1 and VM2 before you restore the other Routing VMs.

Note

Before performing the following procedure, make sure the VM disk space and storage pools are in place. Refer to the procedures To create disk space and To create the VM storage pool on Create a Virtual Machine (VM) for the MA-RMS.

Restore the VM(s) on a VHE Host

This procedure provides instructions about restoring a VM(s) on a VHE Host using the configuration file from the initial install and a complete backup file.

Prerequisites
  • During the initial install, you are expected to save a copy of the install package, installation configuration and backup files.
Start
  1. Log onto a VHE Host or a Linux workstation on which you want to execute the restore.

  2. Enter the following command.

    Example
    ./dsc_swe_18_0_0_nb20190317_KVM.sh restore --config DSCSWe3.conf --backup DSCSWe3-slot1-bak-06-06-18-110824-Complete-DSCVM.18.0.tar.gz
