MD3000i Battery replacement

Hello,

I have one MD3000i require to do battery replacement.   It is a single channel Storage.  Reference to others post the steps is I think is about:

1. Stop all activity to the array

2. Umount the virutal disk from host.

3. Power off the RAID Enclosure

4. Power off the host machine which attached if possible.

After replacement done.

1. Power on RADI enclosure

2. Power on hostname machine which attached

3. Check mount point.

Question:

1. The above steps is correct.  Any comment?

2. Does it require to reset battery age? As some new version of MDSM did not have this features.  So how to do it from SMCLI or execute script if need?

Thanks!
