Source: raidsrv
Event ID: 505
Type: Warning
Description:
<RU0505> [CTRL: RAID controller number] Temperature of battery is
high.
If the event shown above is registered, check the current cache mode of the RAID controller by using the Universal
RAID Utility.
→ If the current cache mode is set to "Write Back", it is not the problem when operating the system.
→ If the current cache mode is set to "Write Through", the temperature of the battery raises temporarily due to
refresh operation. Refresh operation stops when this event occurs, thus the temperature drops. Refresh
operation is resumed after the battery has cooled down. Once the refresh operation is completed, the current
cache mode is changed to "Write Back". If "Write Through" is retained even after 24 hours, the battery may
be faulty. Replace the battery.
Event ID508:
When the RAID controller has an additional battery the following message is registered in the RAID log of the
Universal RAID Utility and OS log (Event Log or Windows, syslog of Linux).
