Write lights on all the time on RAID 5 Array on a Proliant 6000

I have an old Proliant 6000 with six drive bays. 1 is a 4.3gb Wide Ultra SCSI online spare for 2 and 3 which are mirrored system disks. These are fine, the problem is with disks 4,5 and 6 which is a RAID 5 Array of 9.1 Wide Ultra SCSI's. This server is running NT4 (SP6) it's a BDC for a domain with less than 25 users and all it does is logon authentication and store a few images which are never accessed. As you can imagine it's not very busy. My problem is that the the write lights on the RAID array stay on for all three disks in the array for 4 minutes solid and then off for 30 seconds. This loops all day. It's not doing anything though, you can use Performance monitor to make sure nothing is going on using all the Physical and Logical disk counters you need. Nothing is writing to this array so why would the lights stay on like they are being written to.... Any ideas would be welcome.

It's not causing a problem by the way I just want the lights to flash like they do on the 3000 and ML370 RAID arrays in the room. Maybe because it's Christmas I feel I should be more coordinated....

Hello Roger,
You did not mention the array controller you are using. Anyways please update the firmware of array controller and see if there is a change in the behaviour. If you let me know the array controller I shall post the link for the latest firmware.

Re: Write lights on all the time on RAID 5 Array on a Proliant 6000

I'm not entirely sure without re-booting. However if you look in Control Panel\SCSI Adapters\Devices\Compaq Drive Array\ and then look at the firmware version on the settings tab of the Compaq Disk array it says Firmware Revision 2.02 it calls the Compaq Disk array CpqArray but that's not what your after is it. Can I tell without re-booting. The thing is I haven't bothered to put the Insight stuff on this server.

Hello Roger,
I suspect you have Smart 2 series array controller. You certainly can find out as to which controller do you have by going in Start---Programs---Compaq Utilities( I believe) then Array Configuration---Highlight the Array controller and then at the bottom you will see a Button(More Info). This should definitely tell you which controller and the firmware.

Regards,
