Veritas Access Installation Guide

To add the new node to the cluster

1. Sign in to Veritas Access using the master or the system-admin account.
2. In the Veritas Access command-line interface, enter the Cluster command to enter the Cluster> mode.
3. To add the new nodes to the cluster, enter the following:

   Cluster> add node1ip, node2ip.....

   where node1ip,node2ip,.... are the IP address list of the additional nodes for the ssh connection.

   It is important to note that:

   • The node IPs are preserved and additional required are assigned from (unused) pool of physical IPs.

   • The physical IPs of new nodes are usable IPs found from the configured public IP starting addresses.

   • The virtual IPs are re-balanced to the new node but additional virtual IPs are not assigned.

     Go to step 3 to add new virtual IP addresses to the cluster after adding a node.

   • The IPs that are accessible to the new nodes should be given.

   • The accessible IPs of the new nodes should be in the public network, they should be able to ping the public network's gateway successfully.

   For example:

   Cluster> add 192.168.30.10

   Note:

   You cannot add nodes to a two node cluster when the writeback caching is enabled. Before you add a node, change the cache mode to read and then try again.

4. If a cache exists on the original cluster, the installer prompts you to choose the SSD disks to create cache on the new node when CFS is mounted.

   1) emc_clariion1_242
   2) emc_clariion1_243
   b) Back to previous menu
   Choose disks separate by spaces to create cache on 192.168.30.11
   [1-2,b,q] 1
   Create cache on snas_02 .....................Done
   

5. If the cluster nodes have created FSS pool, and there are more than two local data disks on the new node, the installer asks you to select the disks to add into the FSS pool. Make sure that you select at least two disks for stripe volume layout. The total selected disk size should be no less than the FSS pool's capacity size.

   Following storage pools need to add disk from the new node:
        1)  fsspool1
        2)  fsspool2
        3)  Skip this step
   
   Choose a pool to add disks [1-3,q] 1
        1)  emc_clariion0_1570 (5.000 GB)
        2)  installres_03_sdc (5.000 GB)
        3)  installres_03_sde (5.000 GB)
        4)  sdd (5.000 GB)
        b)  Back to previous menu
   
   

   Choose at least 2 local disks with minimum capacity of 10 GB [1-4,b,q] 2 4
   Format disk installres_03_sdc,sdd ................................ Done
   
   The disk name changed to installres_03_sdc,installres_03_sdd
       Add disk installres_03_sdc,installres_03_sdd to storage pool fsspool1  Done

6. If required, add the virtual IP addresses to the cluster. Adding the node does not add new virtual IP addresses or service groups to the cluster.

   To add additional virtual IP addresses, use the following command in the Network mode:

   Network> ip addr add ipaddr virtual

   For example:

   Network> ip addr add 192.168.30.14 255.255.252.0 virtual

   ACCESS ip addr SUCCESS V-288-1031 ip addr add successful.
