Installing VCS 4.1 Manually on New System

Install VCS manually by using the swinstall utility on System B.

Adding a License Key

After all packages have been installed on the cluster node, use the vxlicinst command to add the VCS license key on the system:

Checking Licensing Information on the System

You can use the utility vxlicrep to display information about all VERITAS licenses on a system. For example, enter:

From the output, you can determine the license key, the type of license, the product for which it applies, and its expiration date, if any. Demo keys have expiration dates, permanent keys and site keys do not.

Create Configuration Files on New System

1. Create the file /etc/llttab that lists both systems.
   Refer to Setting Up /etc/llttab.
2. Create the file /etc/llthosts.
   Refer to Setting Up /etc/llthosts. Set up /etc/llthosts for a two-system cluster.
3. Create the file /etc/gabtab.
   Refer to Configuring Group Membership and Atomic Broadcast (GAB).
4. Start LLT on System B:
     # /sbin/rc2.d/S680llt start
5. Start GAB on System B:
     # /sbin/rc2.d/S920gab start

Reconfiguring VCS on the Existing System

1. On System A, create the files /etc/llttab, /etc/llthosts, and /etc/gabtab. Use the files created on System B as a guide, customizing the /etc/llttab for System A.
2. Start LLT on System A:
     # /sbin/rc2.d/S680llt start
3. Start GAB on System A:
     # /sbin/rc2.d/S920gab start
4. Check the membership of the cluster:
     # gabconfig -a
5. Start VCS on System A:
     # hastart
6. Make the VCS configuration writable:
     # haconf -makerw
7. Add System B to the cluster:
     # hasys -add sysB
8. Add System B to the system list of each service group:
   1. List the service groups:
   
       # hagrp -list
   2. For each service group listed, add the system:
   
       # hagrp -modify group SystemList -add sysB 1

Verifying Configuration on Both Systems

1. On System B, check the cluster membership:
     # gabconfig -a
2. Start the VCS on System B:
     # hastart
3. Verify that VCS is up on both systems:
     # hastatus
4. List the service groups:
     # hagrp -list
5. Unfreeze the service groups:
     # hagrp -unfreeze group -persistent
6. Implement the new two-system configuration:
     # haconf -dump -makero
