Hi !
You can also use the LVM approach.
Create a Volume-Group (ex. vgoraasm) with all of your Oracle-Disks (create 1
Partition with Type LVM on each disk) you want to use in the ASM. The you
can create Logical Volumnes (LV, ex. Lvasmd1) in the VG where every LV is
exactly in 1 Disk (Option in the lvcreate). You need to give oracle:dba the
rights to access the LV (via udev-permissions).
After that you set your ASM-Diskstring to /dev/mapper/vgoraasm* (when using
Device-Mapper) or /dev/vgoraasm/lv* (direct LVM-Usage) and everything's fine
;-)
Works fine for me ;-)
Bye
Frank

Hi,
I am not sure if raw is mandatory, just set the "ASM_DISKSTRING" parameter
in the ASM spfile and all the matching devices will be ASM candidates.
However ideally with raw, you can create a raw for each device and put the
raw devices in
/dev/oraraw
Then you have ASM_DISKSTRING=/dev/oraraw
i.e :
mkdir -p /dev/oraraw/
rm -f /dev/oraraw/*
mknod /dev/oraraw/raw_vot_1 c 162 1
mknod /dev/oraraw/raw_vot_2 c 162 2
mknod /dev/oraraw/raw_vot_3 c 162 3
mknod /dev/oraraw/raw_ocr_1 c 162 4
mknod /dev/oraraw/raw_ocr_2 c 162 5
raw /dev/oraraw/raw_vot_1 /dev/sde1
raw /dev/oraraw/raw_vot_2 /dev/sdf1
raw /dev/oraraw/raw_vot_3 /dev/sdg1
raw /dev/oraraw/raw_ocr_1 /dev/sdh1
raw /dev/oraraw/raw_ocr_2 /dev/sdi1
Best Regards
Yann.

Hello Fabricio,
Yes, I read about ASMlib is not needed but then I must use raw device, or
not?

Hello Jorge,
I don't think the ASMlib are ready for the SLES10 kernel yet.
However you don't need them for your ASM.
ASMlib are not really necessary (and personally I prefer not to use them).
Regards
Fabrizio

Hi everyone,
We are installing a RAC cluster of two nodes on SLES 10 hosted in a Vmware
Server 1.0.1 in a SLES10 linux system.
We have the two nodes ready to start RAC installation and we plan to use ASM
storage for database and quorum file.
How can we configure ASMlib and from where can we download rpm package or
source package? The idea is not to use raw devices.
In OTN I see rpm's for SLES9 but no sources.
Thanks, and excuse my poor english.
