N The NVRAM battery charger does not detect the presence of NVRAM battery Y The NVRAM battery charger has declared the NVRAM battery as failed Y The NVRAM battery is not responding to two-wire serial bus commands N The NVRAM battery charger has aborted the reconditioning of a battery N The NVRAM battery charger has successfully started reconditioning of a battery. N The array has been switched to secure mode due to the condition of the batteries N The array has been switched out of secure mode since the condition of the batteries do not warrant it anymore Y The amber LED that indicates battery failure has been turned on due to a battery failure condition. When this log entry is unaccompanied by the log entry, it indicates that the battery management firmware module was unable to communicate with the NVRAM battery. Possible two-wire serial bus communication error. Y The NVRAM battery internal status indicates that the battery has reached the end of life condition N The status of NVRAM battery is low. This means that the battery charge is less than a specified threshold value N The status of NVRAM battery is good. This means that the battery charge is equal or higher than a specified threshold value N The status of the NVRAM battery is unknown. This may be due to the firmware not being able to communicate with the battery N The battery management firmware has received a request from another firmware module to use the two-wire serial bus Y The battery management firmware module is unable to communicate with the NVRAM battery charger. Possible two-wire serial bus communication error N The NVRAM battery charger has successfully reconditioned a battery N The state of the controller and batteries that are checked before a decision is taken on reconditioning N The eeprom can be communicated with and has valid contents. N Communication with the eeprom has failed. The module assumes that no hardware is present. Y The TWSI bus may have failed, the read after a write resulted in inconsistent data, or the crc checksums in a device and it's mirror (if available) are not correct. N This can is caused when an TWSI bus command fails. The eeprom is marked as unknown until a retry is done or the TWSI bus reports a hard failure. Y This is caused by an invalid state in an eeprom state machine. If this error is found, there is a bug in the firmware which must be fixed. Y The two-wire serial bus module would not allow the read or write request. This is usually due to a bus failure. Y The two-wire serial bus module retried the read and was either not able to get a response from the device, the transaction failed, or the bus failed. In the case of a bus failure, the bus was good at the time the read request was made. Now it has failed.
