Cell Manager Installation

...

• Make sure to meet the prerequisites listed at the top of this page.

• Follow the procedure: Prepare Pre-Installed Operating System.

• Physical servers should use RHEL or Rocky Linux as the operating system (and not CentOS).

• The cell member server should contain disks according to the recommendations made in the sizing process with IBM Support Team, which includes disks for OS, install, and data (one for /data and 6 to 9 additional disks for /data2/3/4...).

• Physical federated cell members with 4 CPU sockets and NVMe disks require special disks and mount points configuration to ensure performance. See Configuring Cell Members with 4 CPU Sockets and NVMe Disks.

• Use Non-appliance Mode and follow the procedure: Non-Appliance Installation
  During installation, the four-letter Installation Environment Name should be identical to the one that was chosen during the Cell Manager installation.
  During installation, when prompted to choose the IP address for the Web Console, choose the IP address of the external network interface.

• Make sure httpd service is running and can be restarted successfully. If an error is displayed during the service restart, please see if the following information helps in resolving it: https://access.redhat.com/solutions/1180103

...

• In case of physical federated cell members with 4 CPU sockets and NVMe disks - use the information gathered at Configuring Cell Members with 4 CPU Sockets and NVMe Disks to map the mount point with the proper disk:

• For all other types of federated cell members servers - you may map the mount points to any disk.
