Veritas Access Installation Guide

To install and configure the cluster

1. Enter one of the following commands to start the installation.

   # ./installaccess node1_ip node2_ip

   Where node1_ip and node2_ip are the public physical IP addresses that are already assigned to the target cluster nodes to install Veritas Access over SSH.

   These are the current IPs assigned to the nodes for the installation communication.

   The example is used to install two nodes. To install another target node cluster, add node3_ip to the command line that is used in this step.

2. The installer checks for the operating system dependencies and automatically installs the required OS RPMs. If the OS RPMs' dependencies are not sorted, the RedHat subscription manager user ID and password are required.
3. The installer installs the Veritas Access RPMs.
4. Choose the licensing method. Answer the licensing questions and follow the prompts.

   1)  Enter a valid perpetual or subscription license key file
   2)  Register with evaluation mode and complete system licensing later
   
   How would you like to license the systems? [1-2,q,?] (2)

5. The installer displays the firewall ports to be opened after the configuration, and asks if you want to open them:

   Veritas Access needs to open the following ports:
   111 Rpcbind (NFS)
   11211 Memcached Port
   123 NTP Service
   139 CIFS Service
   14161 GUI
   161 SNMP Service
   2049 NFS Service
   21 FTP Port
   22 SSH Service
   25 SMTP Port
   30000:40000 FTP Passive Port Range
   3172,3173 Server View Ports
   4001 Mountd (NFS)
   4045 NLM (NFS)
   4379 CTDB Port
   445 CIFS TCP Service
   514 Syslog Service
   53 DNS Service
   5634 VIOM
   56987 Replication Service
   756,757,755 Statd (NFS)
   8088 REST Server
   8143 Object Access Gateway
   8144 Object Access Admin Gateway
   Do you want to proceed? [y,n,q] (y)
   

6. The installer asks the following information to configure the cluster:

   Enter the cluster name: [q,?] 
   Do you want to rename the hosts' name like vac_01, vac_02? [y,n,q,b,?] (n) 
   Enter the public IP starting address or : [b,q,?] 
   Enter the netmask for the public IP address: [b,q,?] (255.255.255.0)
   Enter the number of VIPs per interface: [b,q,?] (0) 1
   Enter the virtual IP starting address: [b,q,?]  
   Enter the default gateway IP address: [b,q,?]  
   Enter the DNS IP address: [b,q,?] (10.0.2.3)
   Enter the DNS domain name: [b,q,?] (community.veritas.com)
   Enter the console virtual IP address: [b,q,?]  
   Do you want to use the separate console port? [y,n,q,b,?] (n)
   Enter the private IP starting address: [b,q,?] (172.16.0.3)
   

   Note:

   Cluster names should be DNS-compatible. Cluster name must be at least three characters and no more than 10 characters long. Allowed characters in a cluster name are 'a-z, 0-9, -' lowercase letters, numbers, and hyphens. Any other character is invalid. Also, if a separate console port is chosen, the first public NIC is chosen to work exclusively as a console port.

7. The installer asks if you want to configure the Network Time Protocol (NTP) server.

   Do you want to configure the Network Time Protocol(NTP) server to 
   synchronize the system clocks? [y,n,q]  y
   Enter the Network Time Protocol server: [q,?]

   If you enter y, you can type in your NTP server. If you enter n, the NTP server is not configured.

8. Installer asks to confirm the entered cluster information.

   The installer detects the network devices, checks the network device's connectivity with the gateway, and displays information about it.

   Checking network configuration .................................... Done
   Detecting network devices ......................................... Done
   Checking network connection ....................................... Done

   Common NICs on all systems:
   
   NIC       Type       Properties     Public
   ===========================================
   ens161    Physical   -              N
   ens192    Physical   -              Y
   ens193    Physical   -              Y
   ens224    Physical   -              Y
   ens256    Physical   -              N 
    
   For the 'Public' field of the NIC:
       Y: means the NIC can connect to the public gateway, and can be selected as
   public NIC.
       N: means the NIC cannot connect to the public gateway, and can be selected
   as private NIC.
       -: means the NIC was not tested if connect to the public gateway.
       blank: means this NIC is excluded or not selectable.
   

   To configure Veritas Access networking, you need to exclude the unused NICs, and to include at least one public NIC, and one private NIC. It is recommended to have two public NICs and two private NICs, and the selected private NICs on all systems should be interconnected.

   If you do want to configure NIC bonding or exclude NICs, enter y.

   If you do not want to configure NIC bonding or exclude NICs, enter n.

   See Excluding a NIC.

   See Creating a NIC bond.

   See Creating a VLAN device .

9. You need to select one of the options from the following for the installation:

   • Manually select NIC

   • Configure NIC bonding

   • Configure VLAN through installer

   Do you want to manually select NICs, or configure NIC bonding or VLAN tagging? [y,n,q] (n) 
   Enter n : If you want installer to do auto network configuration for the cluster
   Enter y : If you want to select public and private NICs manually, configure NIC bonding
             or to create VLAN using installer.

   The installer performs the public and private NIC detection tests on each node of the cluster. If physical or virtual IPs that are entered are less than the required IPs for the cluster configuration, the installer asks you to add the required IPs.

10. Verify that the network configuration details such as the new IP addresses, host name, and other details are correct.
11. The installer prompts to verify the network configuration.

    Verify that the configuration information such as the new IP addresses, host name, and other details are correct.

    Is this information correct? [y,n,q,b,?] (y)
    

12. After you confirm the network configuration details, the installer renames the host name if you have chosen to rename it and assigns the IPs for the systems. The installer also checks the Low Latency Transport (LLT) link status and automatically selects them.

    Note:

    The installer does not check the LLT link status if the InfiniBand NICs are chosen as private NICs.

13. Installer performs the Veritas Access service group configuration.
14. The installer prompts if you want to configure I/O fencing during the installation.

    Do you want to configure I/O Fencing in enabled mode? [y,n,q,?] (y)

    If you do not want to configure I/O fencing, enter n.

    To configure I/O fencing, enter y.

    See Configuring I/O fencing.

15. The installer automatically restarts the cluster nodes to enables the Kdump function for each node.
16. Check the log file to confirm the installation and configuration. Logs can be found in /opt/VRTS/install/logs/.
