Re: Array Enclosure Battery: NONCRITICAL

We've had several of these recently. HP will replace the battery, its a hot swap unit. The only issue is while it is failed or charging the write cache will not be enabled.

You may also want to check your controller firmware revision. HP are recommending HP11 to us as earlier revisions may be reporting battery problems in error.

Re: Array Enclosure Battery: NONCRITICAL

It is important to have any questionable battery replaced, and HP will do it without question, for this reason: in this array, this battery keeps the write cache data alive through power failures (up to several days long, but not forever). If the battery is marginal or questionable, it may not keep the critical write cache data alive more than a second or two, or maybe zero. That would be bad. Write cache is mirrored to the second controller, but the odds of a controller failing during a power failure are vastly higher than one failing as it sits quietly running.

Get it replaced, post-haste. As I said, HP understands the critical nature of this item, and will replace it upon the first incident of hiccup or log entry.

Good Luck!! --bmr

Re: Array Enclosure Battery: NONCRITICAL

Hi,

We had the same issue in three FC60 arrays at the same time. Even upon replacing the battery, amdsp -a still was at NON-CRITICAL.

Once the replaced battery is fully charged, give

#ammgr -b /arrayalias

This resets the battery age to zero.

Was passing through the forums when I initially had the situation, and thought that I should update this section, as it may be useful for some.

Thanks
