Re: finding which disk inside the array is bad?
1. replace all SCSI cables. Make sure daisy-chain cable between X and Y is not shorter than 1m;
2. replace terminator - make sure replacement term is also HVD (C2905A, A1658-63013 or A1658-62024);
3. patch your system (see my reply above).
And then we will see

Re: finding which disk inside the array is bad?
Did you mean that the daisy chain cable shouldn't be shorter than 1 meter? cause what I have right now is certainly shorter than 1 meter and have been using for all these years. I just patched the box with the May 2003 QPack, going to install the HWE bundle next. After rebooting the machine after the patch was installed, got an error for inode 999 has and went through the fix process and continue starting the machine. I am going to remove the hard drive A6 which happened to be the 50G drive and rebuild the array. It was a regular seagate drive put inside the hp array hard drive case. I can't find the cable C2905A but I have C2981A instead. I will also change the terminators later on.
Thanks.

Re: finding which disk inside the array is bad?
Anyway, you need to act systematically to find defective component (within software or hardware). Write an action plan and replace components one-by-one. This way you can find bad component. Although there's another way - replace everything at once and see if it will fix. If yes, then return old components and see if problem will appear again. As soon as it will appear, last installed component is bad.
These are just basic troubleshooting hints...
About cable lenght. I've heard something about it, but I believe it may cause SCSI events, but not PV powerfails

Re: finding which disk inside the array is bad?
So far, I haven't seen any errors. Basically, I removed the disk A6 and replaced the cable which connects the array and the K class. The system is been up for about 20 hours and looks good. Thanks for all the help and advices, really appreciate it. I will let you know if anything new comes up.
Thanks again.

Re: finding which disk inside the array is bad?
I don't have another HVD on that server. But after I replaced the terminator and all the cables. It seems to be working fine. Its still a mystery to me. Thanks for all the advice.
