Supercap Replacement

[tapelibraryfixr]

Hi

i recently had a an error appear in the gui.

turns out the supercap is at 70%. i replaced it, but it still shows as having 70% charge.

Does it do a learn cycle after a certain amount of time or can i tell it too?

Thanks

Hello @tapelibraryfixr,

Are you seeing this on GUI? Probably it is still showing 70% level due to cached information. After 24-48 hours of replacing the supercap, please run a fresh healthcheck from CLI and see the charge level.

First - the Supercap on the MSA is not a replaceable FRU. If you replaced it as stated, it might not be the correct part for the system.

You did not mention which MSA array you are having an issue. Depending on the model and firmware version the fix may be in upgrading to the lastest version. We have had some issues on specific models where a false message is displayed. Upgrading to the latest version corrects the message.

There is no learn cycle nor can you initiate any action on the SuperCap.

Hi,

Could you confirm the MSA model (ex: P2000 G3, MSA 2040 etc) and current firmware version?

Please execute the following commands to verify the array basic health status:

show system

show controllers

Check the event logs for any alerts related to low charge on supercap.

These events usually appear just after a storage controller restart.

As Shawn mentioned supercap is not a replaceable part and entire controller needs to be replaced for any supercap related hardware issues.
