Introduction
Disk commissioning methods
A physical or virtual station that hosts CLM software requires a specific disk partitioning scheme. You can create the required disk partitions on the station:
-
during the deployment of a RHEL OS disk image, as described in Disk-image deployment for CLM
-
after a manual RHEL OS installation, using the partitioning scheme in Disk partitioning for live deployments
Supported file systems
For OS-deployed disk partitions such as /, /home, /tmp, /opt, and /var, the CLM supports ext4 or XFS, with the following exception:
For CLM application partitions such as /opt/nsp and child partitions, ext4 is required, with the following exception:
Additional disk configuration
Regardless of the disk deployment method, each partition created after the OS installation requires the additional configuration described in To configure and mount a CLM disk partition.
Disk-image deployment for CLM
The CLM uses NSP OEM disk images for deploying a RHEL OS instance. Images are available in the following formats:
The following image is available in each format:
Note: RHEL image deployment is authorized only for CLM software installation, and not for the installation of any other Nokia or third-party product.
A RHEL disk image:
-
has all required and optional OS packages to support CLM software deployment
-
does not include any product-specific packages or application files
qcow2 image deployment
For qcow2 image deployment, see To deploy a RHEL qcow2 disk image.
OVA image deployment
Deploying the CLM on VMWare has the following requirements.
-
You must ensure that each non-LVM partition is mounted using the partition UUID, rather than the block device name; see To configure disk partitions using device UUIDs for information.
-
If you use cloud-init to set the IP address of a CLM VM on VMWare, you must perform To apply the VMware cloud-init workaround before you attempt to install any CLM software on the VM.
For general OVA image deployment information, see the documentation for your virtualization environment.
Note: For a CLM deployer host or CLM cluster VM deployed using the OVA image, it is strongly recommended that you mount the /opt directory on a separate hard disk that has sufficient capacity to allow for future expansion.
