Inadvertently shutting down the secondary companion

Currently, if the secondary companion is brought down when its in a failback status (that is, @cmpstate = 14) and the failback switch is set to Auto-failback, the resource group cannot be brought back online by FailSafe.

To recover:

1. Set IRIX FailSafe to manual failback on the secondary node. As “root”, enter the following at the command line:

   cd /var/cluster/ha/resource_types/SYBASE_DB
   

2. As “root”, edit the SWITCHES file so that AUTO_FAILBACK is set to 0.

   You need not restart FailSafe for this setting to take effect.

3. Bring the resource group online. See “Bringing the primary resource group online”, but use sec_rg instead of pri_rg for the Resource Group name.

4. Set IRIX FailSafe to automatic failback on the secondary node. As “root”, issue:

   cd /var/cluster/ha/resource_types/SYBASE_DB
   

5. Edit the SWITCHES file to set AUTO_FAILBACK to 1.
