Re: Hard drive failures



fixed

I signed a SOW today to take my 2 RAID 5 sets to RAID 6 w/hot spare.

It will be a few weeks until it gets done, but it will get done.

Jeff,

Reviewed this cover letter, PTF was auto downloaded Tuesday, 2/25.
It can be applied immediately, but states that IPL is needed for
activation.
I didn't see the same PTF for V6R1, still looking.
Does this affect all disk drives and controllers?
Probably should get this installed ASAP, what does the group think?

I don't believe this has anything to do with the hard drive failures I'm
having because

1) I think it's for SAS drives (just a guess) and I'm pretty sure mine are
all SCSI
2) I don't get any of those source reference codes

OTOH, it does say "parity updates" in this cover letter and SNDPTFORD
evidently thinks I need it.

Thought I would ask.

Jim,

We've had our share of catastrophic failures, back in the S/38 3370
days, (no Raid protection) one year we had 3, it was a perfect
diagonal on the
12 month calendar. Then in the AS/400 years when a 3rd party vendor
doubled your disk capacity if you swapped your IBM memory and
controllers for theirs. Over time not very reliable.

Yes, we've been lucky in the last 10 years. Failures will occur, but
hopefully not as catastrophic with all the newer built in redundancies.

We have SSD drives on our new P7-740. Has anyone had a SSD drive fail?

Paul

All that means is you are living on borrowed time. You may not have a
catastrophic failure, but are you willing to bet your paycheck, and
those of all your co-workers paychecks on it?

I'm happy Holger's systems are holding up, it proves the hardware is
top notch. That does not change my premise that the statistics are
going to eventually get you.

On our old Power5 9406-550
36 4328 drives - 1 failure from Nov 2005 to Feb 2013, and that drive
failed gradually over a 2 month period. 8/15/11, failed on 10/8/11.

Depends...

our internal statistics on older boxes:

- 73 drives 6717 (!) on old boxes - no failure in the last 12 months
- 168 drives 6718 on old boxes - 1 failure in the last 12 months
- 40 drives 6719 on old boxes - 8 failures in the last 12 months
- 180 drives 4326 on aged boxes - 1 failure in the last 12 months
- 168 drives 4327 on i5 boxes - 9 failures in the last 12 months
- 84 drives 4328 on i5 boxes - 3 failures in the last 12 months

drives in Power6 boxes and newer: <1% of failing drives in 12 months.
Nothing to worry about.

The old 6717 are rock-solid unless you power them down. And yes - we
run a lot of old customer boxes for archive purposes. Old software
forces them to
:-)

Age. Your mean time between failure date on those drives has long
since passed.
