RE: Disk Failure

[David Breisacher <DBreisacher@xxxxxxxxxxx>]

Al & all other parties concerned about iSeries disk - 

My name is David Breisacher and I am the CEO/Chairman of BCC Technologies.
Before I comment on any IBM disk failures I must let everyone know that my
company manufacturers disk for the iSeries. My comments here are not
intended to promote BCC nor disparage IBM. I must also point out that I am a
strong advocate of IBM technology since we deal with the IBM Information
Technology Group. 

So what is going on with all these failing disk? You may all be surprised to
find out that the answer is less simple than just pinpointing a serial
number list of drives? 

Before any concise answer can be formulated we must address some obvious
questions.

1. Could the failing drive be rebuilt or was a new drive required? This will
help us determine if the problem is software or hardware related. 
2. Was the replaced drive an Ultrastar XP, 2XP, 18XP, 9LZX, 18LZX, or 36LZX
drive? 
3. What was the capacity of the drive?
4. Where was the drive located within the iSeries bus?
5. What was the RAID parity (4 or 8 drive) configuration? 
6. Was RAID or Mirroring being utilized?
7. What SCSI IOP was being utilized?
8. What was the iSeries model and OS400 level?
9. What was your last CUM level, hiper, and individual disk related ptf
apply date?

Please send me answers to any of these questions and I'll give you my
opinions. I have to run into a meeting so that's all for now.

I'm trying to do that, but IBM is not being very cooperative with details.
Apparently all of the "suspect" drives were built in Singapore.

Is it possible to narrow it  down to some manufacturing /ship/install date
window?
Just  to get an idea of the scope of the exposure and if there is an END
DATE yet?

Al When were your  manufactured/shipped?

     Hi,
     I have looked at an IBM website that says the 6717's are 8.58GB / 10K
     rpm.
     Are these the disks you refer to ? We have ten in our new (to us) 730.
     Should I be worried ?
