NetApp has identified an issue in FAS/V32XX and SA320 that can lead to a low battery capacity (charge) condition. This is caused by an FC-MTO error condition of the battery, resulting in the battery not being charged as expected. The system issues a low-level warning if the battery capacity drains to 80 hours runtime. If no action is taken and the battery continues to drain to a critical low level of 72 hours runtime, the system initiates a 24-hour shut-down sequence as a protective measure to safeguard NVMEM.
This has affected one of our customers already and triggered a shutdown of the controller. Fortunately, the system was a HA Clustered pair and only affected one controller, so a takeover was initiated and services were not impacted.
NetApp has posted the new battery firmware on the NetApp Support site for immediate update of systems. Detailed instructions are provided in KB article 2016592.
For systems with a Service Processor that cannot connect to an internal Web server, the new battery firmware is bundled with Service Processor firmware package revision 1.3, which NetApp anticipates releasing in May 2012.
