Connect to the I/O Domain Console

  1. Before starting the restore process, identify the primary domain that is hosting the I/O Domain.
    1. Identify the list_constraints files.

      For each primary domain, the backup tool creates a .list_constraints file.

      root# su - oscbackR
      oscbackR$ cd osc-config-backup/domains
      oscbackR$ find . -name *.list_constraints
      ./ssc1dbadm0101/ssc1dbadm0101.2016.06.14.05.01.list_constraints
      ./ssc1dbadm0201/ssc1dbadm0201.2016.06.14.05.01.list_constraints
      
    2. Locate the list_constraints file that lists the I/O Domain.

      An I/O Domain is only listed in one of the .list_constraints files.

      Use the grep command to identify which .list_constraints file lists the I/O Domain. Replace mydomain with either the I/O Domain's name or host name.

      oscbackR$ grep -c mydomain ./ssc1dbadm0201/ssc1dbadm0201.2016.06.14.05.01.list_constraints
      0
      oscbackR$ grep -c mydomain ./ssc1dbadm0101/ssc1dbadm0101.2016.06.14.05.01.list_constraints
      10

      In this example, the I/O Domain is listed in the ./ssc1dbadm0101/ssc1dbadm0101.2016.06.14.05.01.list_constraints file. Based on that file name, you can determine that ssc1dbadm0101 is the primary domain that hosts the I/O Domain.

  2. Connect to the primary domain.

    A best practice during a restoration involves staying connected to the I/O Domain's console.

    # ssh ssc1dbadm0101
    
  3. Check that the I/O Domain is present.
    # ldm list | grep hostname
    ssccn1-io-hostname active   -n----   5010  8  16G   0.1%  0.1%  52m
    

    where hostname is the domain's host name and ssccn1-io-hostname is the domain's name.


    Note -  The domain might not be in an active state.
  4. Connect to the domain console.

    Use the port number returned by the previous command. In this example, the port number is 5010.

    # telnet localhost 5010
        Trying 127.0.0.1...
        Escape character is '^]'.
        
        Connecting to console "domain-name" in group "domain-name"
        Press ~? for control options ..
    

    Remain connected, because useful messages might be displayed on the console.
