Hi, I've setup something similar with Oracle RAC which also requires raw device mappings. For this I used both multipathing (which creates the /dev/mapper/<file_names>), and rc.local (which provides the /dev/raw/ mappings to the /dev/mapper/ file names. There's a very good how-to document on Oracle's Metalink site explaining how to do this on rhel 5. Regards, Geoff. -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of raj sourabh Sent: Wednesday, 26 January 2011 8:27 a.m. To: General Red Hat Linux discussion list Subject: Re: Raw device mappings of multipath disks in RHEL5.4 Hi, If the mapper device have been created suceesfully then you may try to map the raw devices on rc script (rc.local) This worked for me. My rc.local looks like; MAKEDEV raw sleep 2 raw /dev/raw/raw1 /dev/mapper/mpath1p1 Hope this helps.
