If you have a critical disk group that you do not want to become disabled in the case that the master node loses access to the copies of the logs, set the disk group failure policy to leave. This prevents I/O failure on the master node disabling the disk group. However, critical applications running on the master node fail if they lose access to the other shared disk groups. In such a case, it may be preferable to set the policy to dgdisable, and to allow the disk group to be disabled.

The default settings for the detach and failure policies are global and dgdisable respectively. You can use the vxdg command to change both the detach and failure policies on a shared disk group, as shown in this example:

# vxdg -g diskgroup set diskdetpolicy=local dgfailpolicy=leave
