      7. Installation and configuration issues
        1.  
          After you restart a node that uses RDMA LLT, LLT does not work, or the gabconifg - a command shows the jeopardy state
        2.

          Installer does not list the initialized disks immediately after initializing the disks during I/O fencing configuration
        6.  
          If the same driver node is used for two installations at the same time, then the second installation shows the status of progress of the first installation
        7.  
          If the same driver node is used for two or more installations at the same time, then the first installation session is terminated
        8.  
          If you run the Cluster> show command when a slave node is in the restart, shutdown, or crash state, the slave node throws an exception
        9.  
          If duplicate PCI IDs are added for the PCI exclusion, the Cluster> add node name command fails
        10.  
          If installing using a response file is started from the cluster node, then the installation session gets terminated after the configuring NICs section
        11.

        12.  
          Installer appears to hang when you use the installaccess command to install and configure the product from a node of the cluster
        13.

        17.  
          When performing a rolling upgrade from Veritas Access 7.3.0.1 to 7.3.1 on RHEL 7.3, CIFS services get into a faulted stated after the nodes are upgraded to Veritas Access 7.3.1
        18.  
          Veritas Access installation fails if the nodes have older yum repositories and do not have Internet connectivity to reach RHN repositories
      8. Networking issues

          CVM service group goes into faulted state unexpectedly
        2.  
          In a mixed IPv4 and IPv6 VIP network setup, the IP balancing does not consider IP type
        3.  
          The netgroup search does not continue to search in NIS if the entry is not found in LDAP

          For the NFS-Ganesha server, bringing a large number of shares online or offline takes a long time
        9.  
          NFS client application may fail with the stale file handle error on node reboot
        10.

        3.  
          If you have upgraded to Veritas Access 7.3.1 from an earlier release, access to S3 server fails if the cluster name has uppercase letters
        4.  
          If the cluster name does not follow the DNS hostname restrictions, you cannot work with the ObjectAccess service in Veritas Access
        5.  
          ObjectAccess operations do not work correctly in virtual hosted-style addressing when SSL is enabled
        6.

          Episodic replication failover does not work
        11.  
          Continuous replication fails when the 'had' daemon is restarted on the target manually
        12.  
          Continuous replication is unable to come in replicating state if the Storage Replicated Log becomes full
        13.  
          Unplanned failover and failback in continuous replication may fail if the communication of the IPTABLE rules between the cluster nodes does not happen correctly
        14.  
          Continuous replication configuration may fail if the continuous replication IP is not online on the master node but is online on another node
        15.  
          If you restart any node in the primary or the secondary cluster, replication may go into a PAUSED state
      14. SmartIO issues
        1.

    2.  
      Displaying the man pages
    3.  
      Using the Veritas Access product documentation

If a user is added on the target side, the initiator cannot see the LUNs

While discovering targets, the Veritas Access initiator does not ask for credentials, and takes the default credentials. Hence, the initiator is unable to log into the targets. As a result, the target status on the initiator becomes OFFLINE and LUNs are not visible to the initiator.

Workaround:

Log in from outside of the CLISH using the following iscsiadm commands. Execute this command on both nodes so that the disks (LUNS) become FSS disks.

# iscsiadm -m node -T <target-name> -p <portal-ip> 
--op=update --name node.session.auth.authmethod --value=CHAP
iscsiadm -m node -T <target-name> -p <portal-ip> 
--op=update --name node.session.auth.username --value=username

iscsiadm -m node -T <target-name> -p <portal-ip> 
--op=update --name node.session.auth.password --value=password
