lh6000r, datafiles broken

Dmitry Melekhov_2 — Tue, 29 Jan 2002 05:58:18 GMT

Hello!

We bought HP LH6000r for production and test R/3 systems.
We use R/3 4.6C, Oracle 8.1.6.1 and Suse Linux Enterprise Server 7.
But I have very bad problem- after installation I have broken database.
Intergarted raid controller, 12 HDD drives.
There is no difference between raid1 or raid5- database is broken
Also I tried kernel 2.4.7 and 2.4.16 with no success.

Are all the hard drives online? This can be viewed from Ctrl-M Express Tools (during POST).

We should first isolate if this is a specific problem with a database application or the NetRAID RAID array. Hardware or software?

Hello!

Looks like there are really 2 problems:

1. Datafiles corruption on raid 5 with stripe size 4K. May be all is OK with default stripe size 64K,
not shure yet.
2. There is no real corruption with
raid1, this is my misunderstanding- SAP R/3 reported inconsistent database, this is fixed in new R/3 binaries.
