Re: [suse-oracle] OUI ASMLIB disks recognition (ORCL:*)

Hello,
I've modified the /etc/sysconfig/oracleasm file and the parameter 
ORACLEASM_SCANORDER=dm.
And now the installer discover the ASMLIB disks automatically.

Because the multi-path was created usind dm devices.

oracleasm createdisk ocrvd01 /dev/dm-1
oracleasm createdisk ocrvd02 /dev/dm-5
oracleasm createdisk ocrvd03 /dev/dm-9
oracleasm createdisk data01 /dev/dm-2
oracleasm createdisk data02 /dev/dm-6
oracleasm createdisk data03 /dev/dm-10
oracleasm createdisk reco01 /dev/dm-3
oracleasm createdisk reco02 /dev/dm-8
oracleasm createdisk reco03 /dev/dm-11
The Metalink note 359266.1 help something to understand this.

Any has any doc reference to multi-path document on Suse/Linux?

Thanks
Arturo
