HP ProLiant DL 180 G6 P410 RAID recovering stuck at 1%

Hi,

We just have change an hard drive on a HP ProLiant DL 180 G6 with RAID controller P410 on RAID5 with 5 drive.

The the first logical drive start recovering, and since yesterday it is stuck at 1%.

I try to figure what was the problem with the HP Array Configuration Utility in CLI.

When I type "ctrl slot=1 show"

The result is:

"Smart Array P410 in Slot 1
   Bus Interface: PCI
   Slot: 1
   Serial Number: PACCR9SYI9BL
   Cache Serial Number: PACCQ9SYJ4DH
   RAID 6 (ADG) Status: Disabled
   Controller Status: OK
   Hardware Revision: C
   Firmware Version: 2.50
   Rebuild Priority: High
   Expand Priority: Medium
   Surface Scan Delay: 15 secs
   Surface Scan Mode: Idle
   Queue Depth: Automatic
   Monitor and Performance Delay: 60  min
   Elevator Sort: Enabled
   Degraded Performance Optimization: Disabled
   Inconsistency Repair Policy: Disabled
   Wait for Cache Room: Disabled
   Surface Analysis Inconsistency Notification: Disabled
   Post Prompt Timeout: 0 secs
   Cache Board Present: True
   Cache Status: OK
   Cache Status Details: A cache error was detected. Run a diagnostic report for
 more information.
   Cache Ratio: 25% Read / 75% Write
   Drive Write Cache: Disabled
   Total Cache Size: 256 MB
   Total Cache Memory Available: 144 MB
   No-Battery Write Cache: Disabled
   Cache Backup Power Source: Batteries
   Battery/Capacitor Count: 1
   Battery/Capacitor Status: OK
   SATA NCQ Supported: True"
   
So I have generate an ADU (see attached file).

I have also try to change the controller cache ratio by this command "ctrl slot=1 modify cr=75/25" (the actual value is 25/75)

And for result I've got this:

"Error: This command did not complete properly. Please check your configuration
       for possible hardware or configuration problems. Use the "show" command
       on devices to show additional details about the configuration."
       
How can I identify the true problem and try to resolve it ?

Best regards.

John.
