Workarounds
1. Install an Uninterruptable Power Supply: Customers with an Uninterruptable Power Supply supporting the server in
question will not experience a power interruption which will lower the possibility of experiencing an issue.
2. Determine if the RMFBU is failed and cache policy remains in Write Back, customers running RAID Web Console 2
will be notified of this issue via a pop up warning message that the RMFBU has failed, and the RMFBU failure will
be noted in the RAID log section of the main view of RAID Web Console 2. The RAID volume write policy should
be verified to be in Write Through mode by navigating to the RAID Volume Properties view, and this cache policy
should then be reverified 2 minutes later to be sure that the cache policty remains in Write Through mode while the
RMFBU is in a failed state.
3. As an immediate workaround and precaution, customers may choose to manually set the RAID volume cache
property to write through until the system can be updated with the RAID firmware that resolves this issue. This can
be accomplished in one of three ways listed below:
a. During power on POST, enter the BIOS Console utility by pressing ctrl+g when prompted, and navigate to
the RAID volume properties section and change the RAID write cache property to write through.
b. Within the operating system, install and launch the RAID Web Console 2 utility. Navigate to the virtual drive
window and right click on the virtual drive, select modify virtual drive properties, select the RAID write cache
property and change it to write through.
c. From within the operating system or from within EFI, using the Command Tool 2 utility, send the following
command to the RAID controller:
CmdTool2 -LDSetProp -WT -LALL -a0*
*Where -LAll= All logical drives and –a=controller number
