Implementing message persistence files on a SAN

You can implement message persistance files on a SAN, but there are some risks.

To prevent disk failures or node outages from causing a prolonged MQSeries® outage, you should consider putting the MQ logs and files used to store messages on a SAN that is accessible from multiple nodes. This allows you to restart MQ from another node.

Risks in implementing message persistence files on SAN

In the previous examples, the shared storage remains the single point of failure. One option is to configure active/passive SAN devices with the primary SAN replicating data to the standby SAN. In the event of a SAN failure, the primary MQ node would release the primary SAN and acquire the standby SAN.
