AFF A400/FAS8300/FAS8700 shuts down with nvmem.battery.currentHigh or no charge alerts
Applies to
- AFF A400
- FAS8300
- FAS8700
- ONTAP 9
Issue
Symptoms
- The following errors are reported prior to node shutdown:
Sun Nov 26 18:06:47 +0900 [cluster-01: env_mgr: nvmem.battery.noCharge:alert]: The NVMEM battery is requesting to be charged but the charger is not charging the battery. To prevent data loss, the system will shut down in 20 minutes.
Sun Nov 26 18:26:47 +0900 [cluster-01: env_mgr: monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (Battery not charging)
- Node may also report high current in EMS log before shutdown:
Tue May 10 06:47:09 -0400 [cluster-01: env_mgr: nvmem.battery.currentHigh:EMERGENCY]: The NVMEM battery current is critically high (1725 mA). To prevent data loss, the system will shut down in 5 minutes.
- The following AutoSupport type might be seen:
HA Group Notification from cluster1-01 (BATTERY (no charge)) EMERGENCY
- In some cases, battery capacity low is also reported as per AFF A400 and FAS8300 Environmental Shutdown (nvmem.battery.capLowCrit) where it is not a false positive related to the battery learning cycle
[?] Sun May 28 09:22:50 -0500 [cluster-01: env_mgr: nvmem.battery.capLowCrit:EMERGENCY]: The NVMEM battery capacity is critically low (0 cycles). To prevent data loss, the system will shut down in 20 minutes.
[?] Sun May 28 09:42:20 -0500 [cluster-01: env_mgr: monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (Battery remain capacity critical)
Confirmation
To confirm the issue use one of the following methods.
Through BMC
- Execute the following command:
BMC cluster1-01> system battery show
- In the results confirm the following:
- Current field shows "0 mA".
- RelativeCharge field show below 71%.
- ChargingCurrent field shows "1000 mA".
Through AutoSupport
- Open the AutoSupport titled "BATTERY (no charge)".
- Navigate to the SP-LATEST-STATISTICS section.
- In the output confirm the following:
- Current field shows "0 mA".
- RelativeCharge field show below 71%.
- ChargingCurrent field shows "1000 mA".
- Navigate to the PLATFORM-SENSORS.XML section.
- In the output confirm one or more of the following show as failed or fault:
- DBlade Battery Voltage
- Battery Charge Failed?
- Battery Charge
- Bat Charging State
