Hi
Many years Ago I installed R/3 on ADABAS-D (forrunner of MAXDB) with only the Databse Data on a raw device all other file systems were not on raw devices.
If I was you I would refer to the Installation Guide for more information.
Regards

> Hi everyone,<br/>Pleas help clarifyng some doubts<br/>Im trying to instal SAP SOLMAN and ERP using MaxDB 7.7 over Linux RHE 5.4<br/>I have blade server Xeon (EMT64) with 2 local disks (raid0+1) and connected to a Storage HP with 8 disks of 450 GB.<br/>I have the following doubts:<br/>1. Does MaxDB data files must reside on a RAW partition, or they can just reside on a ext3 partition? this is because hw vendor claims that usage of raw devices implies all disk as raw.<br/>2. We are configuring al storage as a raid6, but documentation recomends that data files be at raid5 and log files at raid1, does it matter if data files and log files resides at raid6 ?<br/>3. Is it necesary to configura mirror logs if log files are located in the storage system??<br/>4. MaxDB instance (engine) is recomended to be installed at local hard disk or as partition at storage system ?<br/>Please your help with this questions :)<br/>Best Regards<br/>Superbasis
