Dell Disk Array MD3200 RAID Battery replacement
RAID Battery replacement on MD3200 Disc Shelves
Since only have a single raid controller in MD3200 here is what to do to replace the battery.
Power off any host that is attached to your MD3200.
Once the host is powered off then wait about 3-5 minutes for all of the data that is stored in the cache of your MD3200 to be written to disk, then power off your MD3200.
Once the MD3200 is powered off then pull the raid controller out the back of the system & replace the battery.
Once the battery has been replaced then insert the raid controller back into the MD3200 & power on the MD3200.
Wait about 5 minutes for the MD3200 to boot up & come to a ready state.
Once the MD3200 has booted up & is at a ready state then power on all host that are attached to your MD3200.
