Recently our server (IBM xSeries 220) began to had performance problems. Users complaining about problem accessing the files on it. At first it looked like one of the hdd was starting to fail (3 hdd Raid 5). I ran many test and they all went sucessful until i came to the Raid controller test (with ServeRaid, Boot then F2). Got something like 035-260-399-20070804-11-Raid Interface: Failed controller in slot 3.
So now, assuming the problem is my ServeRaid 4L Ultra160 SCSI Raid controller (right?) i'm planning to replace it (not a bad start?). SO the question is short and simple: HOW? (meaning without losing data)
I read i have better chance by using the same model (wich i found i can order, even if it's that old).
The perfect answer would be like:
1. DO this
2. Then do this
But i won't ask for too much :)
Thanks for helping
