MDS600 / C3000 /BL465c G6 & G7 / P711m - Constatnt disk failures and rebuilds
Hi all,
We have invested significantly in HP technologies and having a lot of problems at the moment, most of our systems are now out of warranty and hoping someone may be able to help.
we have a number of MDS600 with HP 3TB drives, 7 drives to a RAID5 array connected to a P711m in a BL465c Gen 7 and Gen 6 server inside a C3000 chassis.
All devices have the latest firmware and the MDS are cabled correctly, the P711m's have less then the maximum drives attached.
for some reason there is not a day that goes by that an array is either rebuilding or failed, we have replaced most of the drives under warranty, replaced the P711m's and cables as well as the blades with the same problems.
logical drive failures are happening every day that require us to re-enable the logical drive.
at present one P711m has all drives rebuilding all other P711m's have multiple drives rebuilding.
any assistance with this would be great.

Hi Torsten,
Yes the SAS switch firmware is the latest as far as i know, (3.5.5.0), we even replaced the SAS switches, they are 6Gb/s.
We started having these problems majorly when we upgraded the 2TB drives that came with the MDS to 3TB HP drives, all drives have been replaced at least once since, under drive warranty, all firmware is up to date via HPSUM for all devices.
P711m's have been replaced along with FBC modules, we have 4 MDS600's and we have the same problem on all of them, the 3TB drives seem to have the biggest problem, with each array having to rebuild or initialise parity at least 1-2 times a week, the other drives are only having issue 1-2 times every 2 weeks or so.
