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
Solved! Go to Solution.

Re: Max Dirty Cache Lines Not Flushed Reached - Warning
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.

Re: Max Dirty Cache Lines Not Flushed Reached - Warning
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.

Re: Max Dirty Cache Lines Not Flushed Reached - Warning
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 ******.
I appreciate you effort about helping others responding in forums
For your Reference I am attaching ADU Report.
Please Help.

Re: Max Dirty Cache Lines Not Flushed Reached - Warning
I know this thread is old.. Just wanted to say that this issue is still occuring. I had opened a case with HP about it too and nobdy could explain what happen. Here's my senario.
I have several DL380G7 server running ESXI 5.x. Each have the P410I controller with Firmware Version: 6.62. One day I came to work and level1 pings me with a ticket stating that they're getting alerts on some of the WIndows servers virtual machines which indicate disk latency. I spend about an hour or so looking through vCenter and I find nothing. So I decide to dig a little bit deeper and run a /opt/hp/hpssacli/bin/hpssacli ctrl all show detail. That's when I see the message "A cache error was detected. Run a diagnostic report for more information." I strarted looking around and to make a long story short, I found 6 other DL380G7 servers with the same error. History indicated that all of these had a drive replaced in the distributed data guarding in the past 90 days. Opening a case with support one and escalting it to level2 only got me the "Try this Firmware" statement. Therefore HP either hasn't been able to root cause this issue or doesn't understand why it's happening. Seems this has been a problem for close to 6 years now.
Here's what I do know.
- Each server has had a Drive failure in the past 90 days.
- If you try to modify the cache read/write ratio, the cache will go to temp disabled.
- Reboot clear the temp disabled and the cache error.
- One unit had a drive failure directly after noticing the "cache error".
My conclusion here, I don't think this is a firmware issue. I think this cache error is being creating due to drive hardware problems, possibly when a secotor goes bad and does a hotfix. to the rediection area of the disk. I can't prove this because due to the limitation of the ESXI OS and the ILO, you can't see the drive counters like you can when you had a SMHP.
