Installing UFM Server Software

The default UFM® installation directory is /opt/ufm.

For instructions on installing the UFM server software, please refer to following instructions per desired installation mode.

• Installing UFM Server on Bare Metal Server

  • Installing UFM on Bare Metal Server- Standalone Mode

  • Installing UFM on Bare Metal Server - High Availability Mode

• Installing UFM Docker Container Mode

  • Installing UFM on Docker Container - Standalone Mode

  • Installing UFM on Docker Container - High Availability Mode

The following processes might be interrupted during the installation process:

• httpd (Apache2 in Ubuntu)

• dhcpd

After installation:

1. Activate the software license

2. Perform initial configuration

Verify that a supported version of Linux is installed on your machine. For details, see UFM System Requirements.

The following table lists the packages that must be installed on your machine (according to the system OS) before you install the UFM server software.

In addition, ensure the following before you begin installation:

• The computer hostname is not defined as 127.0.0.1 and localhost is defined as 127.0.0.1.

• The hostname must NOT appear on the loopback address line. An example of the loopback address is: 127.0.0.1 localhost.localdomain localhost.

• Disable the firewall service (/etc/init.d/iptables stop), or ensure that the required ports are open (see the prerequisite script, refer to Used Ports).

• SELinux is disabled.

• If more than one fabric is managed by different UFM instances, set up different management network spaces for each fabric (not the same LAN).

• Uninstall any previously installed Subnet Manager from the UFM server machine.

• MLNX_OFED 5.x version is installed prior to installing UFM.

• As of UFM v.6.12.0, it is NOT mandatory to configure the IPoIB fabric interface with an IP address.

  In cases where the IP is configured, it is mandatory that the IP is permanently configured and that it starts automatically upon server reboot (the IPoIB fabric interface should be active even if the network is down).

  Note

  The user can set a persistent IP address using Netplan (mainly for Ubuntu systems) or modifying the interface network script (RedHat systems).

• The default MLNX_OFED installation includes opensm. Remove the MLNX_OFED opensm before UFM installation like the following examples:

  RedHat:

  Copy

  Copied!

              
  
              
  rpm -e opensm-3.3.9.MLNX_20111006_e52d5fc-0.1
          

  Ubuntu:

  Copy

  Copied!

              
  
              
  apt purge opensm
          

  By default, ib0 and eth0 are configured as primary access points for the UFM management. If different management and/or InfiniBand interfaces (including bond interfaces) are used as the primary access points, you should modify the configuration file by running the script /opt/ufm/scripts/change_fabric_config.sh as described in the section Configuring General Settings in gv.cfg.

  Change the UFM Agent interface to the Ethernet and/or IPoIB interfaces used for communication with UFM Agent:

  Copy

  Copied!

              
  
              
  ufma_interfaces = ib0,eth0
          

• Reliable and high-capacity out-of-band IP connectivity between the UFM Primary and Secondary servers (1 Gb Ethernet is recommended). This connectivity is used for DRBD synchronization.

• Format two identical servers with dedicated disk partitions for UFM replication. Since the UFM configuration file is replicated to the standby server, both master and standby servers must have the same interfaces.

• Allocate exactly the same size partition on both servers (master and slave) for the replicated data. See UFM Server Requirements for the recommended partition size.

  Partitions should not be mounted and must be zeroed (the file system should not be installed on the partitions). For disk partitioning, see the Linux user manual (man fdisk).

• We recommend establishing a passwordless SSH (via /root/.ssh/authorized_keys file) between the two servers before the installation.

• In fabrics consisting of multiple tiers of switches, it is recommended that the management ports (ib0) of the primary and secondary UFM server be connected to different fabric switches on the same tier (the outermost edge in CLOS 5 designs).

  This is because by default, UFM manages the IB fabric via ib0, port 1 of the HCA. Failure or disconnect of ib0, the IB management port, causes a failure condition in UFM resulting in HA failover.

  When the management ports (ib0) of the primary and secondary UFM server are connected to the same switch, a failure of this switch will result in a disconnect of both UFMs from the fabric, and therefore UFM will not be able to manage the fabric.
