SMI Base Image ISO

The SMI uses a generic installable SMI Base Image ISO (Virtual CD-ROM) for installing the SMI Base image. Currently, the SMI uses a hardened Base OS as the Base image. This ISO image replaces the existing VMDK and QCOW2 artifacts used in the previous SMI releases. The ISO boots and writes the storage device images onto a Virtual Machine (VM) or Bare Metal storage device. Using the SMI Base Image ISO, you can install an OS for the Inception server or install the Base OS for manual deployments (For example, OpenStack).

This ISO image boots the first storage device - with a minimum of 100 GB in size for production - and writes the storage device image to the disk. Additionally, you can use a cloud-init ISO along with the SMI Base Image ISO to configure the cloud-init data, which is required for building a cloud-init ISO. When no cloud-init ISO is found, the SMI uses the default configuration.

Note
  • For providing ISO compatibility on platforms, which do not allow the mounting of ISO files and also for simplifying the deployment on OpenStack, the SMI Base Image ISO can overwrite its own disk (when the disk is greater than 100 GB in size).

  • For accessing and downloading the cloud-init ISO from the repository, contact your Cisco Account representative.

  • The Linux source operating system is upgraded to Ubuntu 20.04.

Note

By default, the user password expiry is set to PASS_MAX_DAYS (/etc/login.defs). Password expiration days must be extended to avoid access lock. For remote hosts, user password days can be configured by using the following CLI configuration:

deployment.node-defaults initial-boot default-user-password-expiration-days [0-9999]

Note

For base images with restricted umask in CM HA nodes, run the sudo command to view the correct DRBD-overview output.
