Max Dirty Cache Lines Not Flushed Reached - Warning

Set up a brand new Proliant ML350 with SA P410i Controller with 256MB Cache, no battery.  Single RAID1 array. Running Win Svr 2008 R2.

 

The Array Configuration Utility is reporting the following:

 

"A cache error was detected. Run a diagnostic report for more information."

 

The Diagnostic report shows the following Warning:

 

"Max Dirty Cache Lines Not Flushed Reached" 

 

Is this warning critical?  If yes, what is solution to fix the problem?  Other than this, the server is running fine.

 

Thanks

Hi,

 

Try to change the percent of the read/write cache in ACU. For example 25% to 75% .

 

Thx

Hi, hm.. firmware upgrade?

If the cache module can be reseated, that might help.
Have you rebooted the machine as well?

ADU might be able to give you some more information.

Changed the read/write ratio to 75/25 and the message went away.  Previous setting was 100/0 and i don't have a battery backup for the cache.

 

Thanks.

From where and How do I change these settings?  Please help me I am newbie in handling servers.  To brief about my situation:  I had 256 Cache and needed to Expand my existing RAID 5 by adding one / two HDD 2 x 300GB.  At tricksguide.com, they informed me that I need 512 BBWC to accomplish the task.  We have finally replace the 256 Cache with 512.  It shows me the very same error:  Cache error detected.  Run HP Diagnostic report ******.

For your Reference I am attaching ADU Report.
