I have a HP Proliant ML350 G5 server running Exchange 2003 sp 2 on a WIndows 2003 sp1 platform . The Array configuration as Follows:
Array 0: Drive 1 and 2 which contains the OS
Array 5: Drive 3-6 contains the exchange Data
Harddrive type: SCSI 72GB
Ram: 3 GB
For the last 4 months, we have had harddrive and array 5 failure. When I restart the server, I hear the harddrive starting up and I hear it struggling then I see amber lights on drive five and sometimes on drive 2. I usually use the Smart Disk to diagnose the problem and I see in the error report: Logical drive have failed on Array 5, all of the data have been lost. All of the harddrive have failed at one point and each time I see amber lights or dead harddrive (no lights), I have replaced the harddrive and allow it to rebuild. I have created some many tickets with HP that they send out a HP Engineer to replace the motherboard, array controller, cache module, and scsi disk backplan and yet we still have the same problem. Two days ago, HP send out another Engineer and he suggested to replace cache module to 512 mb with a battery which I did and I did update the Drivers and firmware. Everything was working fine till today when I see drive 5 have failed again. I have run out of ideas. Thank you for your time.
