This condition is usually an indication that the cache backup battery has fallen below the 72 hour threshold.
The VTrak will generate an alarm and a yellow or red Battery Status LED on the Cooling Unit will light.
There are several things that can cause this condition, the most common being a Battery Recondition cycle.
By default the VTrak is scheduled to perform a Battery Recondition on the 1st of the month every two months. This process begins by discharging the battery, which triggers the alarm condition. After fully discharging the battery the VTrak will recharge the battery.
After completing the battery charging cycle the alarm will continue to sound and will you will have to manually mute the alarm buzzer.
Muting the Buzzer:
- Log into the WebPAM management utility.
- Expand the Enclosure section and click on Enclosure 1.
- Click on the Buzzer tab.
- Click the Mute button at the bottom of the page to turn off the buzzer.
This error condition can also occur if the battery malfunctions, or if the battery is stuck in a continuous charging state. You can attempt to remedy these conditions by performing a Battery Recondition cycle to recharge the battery. If this does not remedy the condidition please contact the Promise Technical Support team to perform further troubleshooting.
Starting a Battery Recondition:
- Log into the WebPAM management utility.
- Expand the Enclosure section and click on Enclosure 1.
- Click the drop-down arrow on the Battery tab and select Start Recondition.
- Select the battery that is malfunctioning.
- Click the Submit button to start the battery recondition.
During a battery reconditioning cycle you may see a loss in subsystem performance due to the LUNs being changed from a ReadAhead/WriteBack state to a ReadCache/WriteThru state. They will revert to their default ReadAhead/WriteBack state when the Remaining Capacity rises above the 72 hour sustain threshold.
