Hello there.
We are running a DL180 G6 with a Smart Array P800 disc controller and 8 harddrives in RAID 5.
When logging into the server using HP System Management Homepage it states that the 'Accelerator' is disabled, and this accelerator have brought us lots of grief.
This particular disc controller are using two batteries to power a disk cache, and initially we interpreted this issue as coming from faulty batteries and replaced the first one, and then both.
This did not address the error message.
As that did not address it we have since then done the following:
Verified configuration
Cleared IML
Upgraded BIOS
Upgraded iLO
Upgraded HP server firmware+drivers
Upgraded centos
Restarting the server and booting to it using ACU:
#ctrl all show
Smart Array P800 in Slot 2
#ctrl all show status
Smart Array P800 in Slot 2
Controller Status OK
Cache Status OK
Battery/Capacitor Status OK
View controller info
#ctrl slot=2 show
Smart Array P800 in Slot

Firmware version in use is 7.24, which is the latest version
Driver version in use is 3.6.28-RH3 (cciss, as hpsa is not compatible)
cciss is now part of the main linux kernel and should be upgraded with a yum update
The latest HP Service Pack for Proliant (2014.02.0B) is installed
The latest BIOS is installed (2013.07.01 A)
The iLO software is updated to the latest firmware (4.26)
A yum update have been issued.
Neither of the above have addressed the issue.
The only time this error message is cleared is shortly after a reboot - but it then re-occurs approx one day later.
Have anyone else experienced this issue or have any information in regards to how to fix it?
Any help would be much appreciated.
Regards,
Olof Nord
