CVPM BATTERY Degraded 교체해도 동일증상일때

When running a ServeRAID M5100 Series SAS/SATA Controller with one (1) of the following cache upgrades, relearn time outs may occur with the Cache Vault Power Module (CVPM) attached to the cache upgrade module.

• ServeRAID M5100 Series 512 MB Flash/RAID 5 Upgrade, option part number 81Y4487
• ServeRAID M5100 Series 1 GB Flash/RAID 5 Upgrade, option part number 81Y4559
• ServeRAID M5100 Series 2 GB Flash/RAID 5 Upgrade, option part number 47C8670

The relearn time outs will occur soon after installation and will have the following three (3) events reported through MegaRAID Storage Manager (MSM)::

 

Event "Battery relearn started" Event "Battery relearn timed out" Event "Battery has failed and cannot support data retention. Please replace the battery"

 

The CVPM will report the following status through MegaRAID Storage Manager (MSM):

Type	CVPM02
Status	Degraded (Needs Attention)
Temperature	Normal
Capacitance	94%
Charging Status	Note

The system has the symptom described above.

Solution

This behavior has been corrected in the Lenovo ServeRAID M5100 Series TMM gas gauge firmware 1.01.

 

This behavior has been corrected in the IBM ServeRAID M5100 Series TMM Gas Gauge firmware 1.01.02.

 

Before updating to 1.01 or 1.01.02, the ServeRAID M5100 SAS/SATA controller must be at a minimal of firmware version 23.33.0-0018.

 

Note 1: When updating the TMM gas gauge firmware through BoMC, there is an issue that will prevent the firmware from being displayed as an available update when the BoMC media has the firmware files for the M5100 SAS/SATA controller. To update through BoMC, follow one (1) of these suggested actions.

 

   1. Remove the M5100 SAS/SATA files from the media
        ibm_fw_sraidmr_5100-23.33.0-0018_linux_32-64.xml
        ibm_fw_sraidmr_5100-23.33.0-0018_linux_32-64.bin
        ibm_fw_sraidmr_5100-23.33.0-0018_linux_32-64.txt
        ibm_fw_sraidmr_5100-23.33.0-0018_linux_32-64.chg

 

   2. Create the BoMC media with only the TMM gas gauge code.
        ibm_fw_sraidmr_5100-tmm-1.01.02_linux_32-64.xml
        ibm_fw_sraidmr_5100-tmm-1.01.02_linux_32-64.bin
        ibm_fw_sraidmr_5100-tmm-1.01.02_linux_32-64.txt
        ibm_fw_sraidmr_5100-tmm-1.01.02_linux_32-64.chg

 

(where TMM = Transportable Memory Module, BoMC = Bootable Media Creator)

 

Note 2: Refer to the following technical tip if TMM update fails.

If the CVPM had previously been marked as bad, then after the TMM gas gauge code update has been applied, the controller will need to be restored to factory defaults to reset the BBUGood flag. To restore the controller to factory defaults, use the following procedure.

 

1. Reboot the system and go into F1 --> System Settings.
2. Select Storage --> LSI MegaRAID Configuration.
3. Select "Set Factory Defaults".
4. Boot the system back into the operating system.

Once back in the operating system, the controller will perform an automatic relearn on the CVPM.

Additional information

This issue is caused by the output voltage generated by the charger circuit operating on the low side of its nominal tolerance. When this issue occurs, the level is outside the charge termination detect value that is programmed in the gas gauge. The gas gauge is programmed onto the Transportable Memory Module.

 

New gas gauge code reprograms the 'max charge level' and 'max learn level' thresholds of the gas gauge to a lower value which more closely matches the actual charger set-point nominal value and increases the 'taper voltage setting' in the gas gauge to allow for wider variations in circuit tolerance.

 

The TMM firmware is separate from the ServeRAID M5100 Series firmware and therefore needs reflashing if the TMM is replaced.

 

To determine the current level of TMM gas gauge code, run the following StorCLI command.

storcli /cX/cv show all (Note: where "X" is the controller #)

Under "Module Version", if the current level is one of these three, it requires updating.

• 25842-06
• 25842-08
• 25842-10

If the current level is one of these two, it already has the latest level and is unaffected by this RETAIN tip.

• 25842-11
• 25842-12
• -v0016fw (for 2GB Flash/RAID 5 Upgrade)

In some situations, the CVPM may have been marked as bad after failing a certain number of relearn cycles. In the event that this occurs, the controller will need to be restored to factory defaults. To determine if the CVPM has been marked as bad, run the following StorCLI command.

storcli /cX show termlog > termlog.txt (Note: where "X" is the controller #)

Starting from the bottom of the log, search up and look for the BBUGood parameter. If the value is "0", the controller will need restoring to factory defaults. The M5100 Series firmware incorrectly believes the CVPM is bad since previous relearn cycles failed.
