Re: Excessive disk drive failures?

This might be seen as "excessive", but you are not the only one seeing increased disk failure rates on P8 / P9 systems.
Are you current with PTF? We had several times the IBM support line first recommended PTF for disk
related issues before disk swap - mostly on systems running RAID6

We have had our 9009 system for about 2 1/2 years. We have 10 59E1-099 drives with 8 in a RAID 10 configuration and 2 hot spares. We have replaced at least 4 of these drives in the time we have had this system, 3 of these drives have failed in the last 14 months, which seams excessive to me. In my previous 20+ years, I think I have only had 3 drives fail. Have I just been fortunate before? Is this a normal disk failure rate? Is this particular design just more failure prone?
