Cluster Server 7.3.1 Configuration and Upgrade Guide - Solaris

To set the order of existing coordination points

1. Start the installer with -fencing option.

   # /opt/VRTS/install/installer  -fencing

   The installer starts with a copyright message and verifies the cluster information.

   Note the location of log files that you can access if there is a problem with the configuration process.

2. Confirm that you want to proceed with the I/O fencing configuration at the prompt.

   The program checks that the local node running the script can communicate with remote nodes and checks whether VCS 7.3.1 is configured properly.

3. Review the I/O fencing configuration options that the program presents. Type the number corresponding to the option that suggests to set the order of existing coordination points.

   For example:

   Select the fencing mechanism to be configured in this
   Application Cluster [1-7,q] 7

   Installer will ask the new order of existing coordination points.
   Then it will call vxfenswap utility to commit the
   coordination points change.
   

   Warning:

   The cluster might panic if a node leaves membership before the coordination points change is complete.

4. Review the current order of coordination points.

   Current coordination points order: 
   (Coordination disks/Coordination Point Server)
   Example,
   1)  /dev/vx/rdmp/emc_clariion0_65,/dev/vx/rdmp/emc_clariion0_66,
   /dev/vx/rdmp/emc_clariion0_62
   2)  [10.198.94.144]:443
   3)  [10.198.94.146]:443
   b)  Back to previous menu
   

5. Enter the new order of the coordination points by the numbers and separate the order by space [1-3,b,q] 3 1 2.

   New coordination points order:
   (Coordination disks/Coordination Point Server)
   Example, 
   1) [10.198.94.146]:443
   2) /dev/vx/rdmp/emc_clariion0_65,/dev/vx/rdmp/emc_clariion0_66,
   /dev/vx/rdmp/emc_clariion0_62
   3) [10.198.94.144]:443
   

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

   Preparing vxfenmode.test file on all systems...
   Running vxfenswap...
   Successfully completed the vxfenswap operation

7. Do you want to send the information about this installation to us to help improve installation in the future? [y,n,q,?] (y).
8. Do you want to view the summary file? [y,n,q] (n).
9. Verify that the value of vxfen_honor_cp_order specified in the /etc/vxfenmode file is set to 1.

   For example, 
   vxfen_mode=customized
   vxfen_mechanism=cps
   port=443
   scsi3_disk_policy=dmp
   cps1=[10.198.94.146]
   vxfendg=vxfencoorddg
   cps2=[10.198.94.144]
   vxfen_honor_cp_order=1
   

10. Verify that the coordination point order is updated in the output of the vxfenconfig -l command.

    For example,
