W1228 ROMB Batt < 24 hr FR463 UF302 312-0448 0NU209

Question:

I restarted another server this morning and after restarting the same message appears on the other server. Now I have 2 servers with the same message:

"W1228 ROMB Batt < 24 hr"

The previous server is now showing the message:

"E1211 ROMB Batt"

this error indicates that the PERC5I RAID battery has less then 24 hours of charge left on it. This is more of a warning message.  How long has the unit been online with the replacement battery?

Question:

I have not put in a replacement battery on it as yet.

What will happen if I don't replace the RAID battery on the server?

If running your PERC without a battery, the error would always be persistant.  As far as your data, anytime there is a battery issue, the controller changes from write back to write thru mode.  Controller would essentially be in a less than optimal mode without the battery as it was intended to use with the array.

You should be able to replace the ROMB battery without losing data or configuration information.  When the battery drains, the PERC controller will automatically turn off the ability of the PERC RAID controller to cache updates, and it will require updates to be written to disk.  This affects performance, although it may not even be noticeable by the user.  When the battery has been replaced, caching should resume.
