Big Problem after Smart Array Change

[Marcus Breitenbach]

äähhm 100% Read / 0 % Write..

but how to change .. i cannot see how

[Norman Kuehn]

On the left select the controller.

On the right under "Common Tasks" choose "Controller settings".

I then see additionally "Logical Drive Array Accelerator Settings" but I do not know exactly how it works...but it sounds worth to check for further information :-)

[Marcus Breitenbach]

Controller Settings: i see
- Rebuild Priority (high medium low)
- Cache Ratio 100% read / 0 % write (nothing to change)
- Surface Scan Delay ( in sec to change)
OK and Cancel
thats all

Logical Drive Array Accelerator Settings

Array Accelerator is enabled and present

[Norman Kuehn]

Perhaps the controller cannot be configured? Hard to believe...

I saw the following by accident when updating the ACU Software in the version history of ACU. I suggest to download the latest PSP (7.91?) and install this version.

Component Name: HP ProLiant Array Configuration Utility for Windows

Component File: cp007578.exe

Version History:
--------------------------------------------

7.85.18.0

Enabled drive write cache for all SAS controllers

7.80.6.0

•  Support SATA NCQ status

7.73.1.0

The ACU utility was modified to display a message informing customers that a firmware update is required if firmware version 2.04 is detected on a Smart Array P400, P400i, or P800 controller.

hi

a p400 controller needs 512 for BBWC to have the option to change it

so Dormelchen do you know if your p400 has 256 or 512?

[Marcus Breitenbach]

our P400 has 256 MB

hi

about P400 too

You can have a P400 with 256mb and a 50/50 cache split, as long as the battery is connected and charged. P400 write performance is terrible without a battery.

Use the system management page to check the battery status.

If there is no battery fitted, you can purchase the battery kit (383280-B21) or the combined 512mb and battery kit (405148-B21)

Cheers,

Justin.

Ok

So the "old" new controller was also defect.
So we had at last 4 defect controllers
