We have installed oracle 10g using ASM(automated storage manager ) on Hpux 11i. ASM requires that we give ownership to the raw disk files to the oracle user. So I did a chown oracle on all the raw disk device files used for ASM. This worked fine for a while.
But the problem started when I added new SAN disks for ASM and kicked of an insf -eC disk on the server , when all the disk device files got regenerated and the raw disk files now got owned by bin:sys and due to this the database instance hangs , as oracle lost ownership to the /dev/rdsk/cxtxdx files.
I tried setting ACLS on the device files but the ACLS don't hold , when i regenerate disk device files.
Anbody have any suggestions or ideas ?
Thanks for ur help

Re: oracle 10g and ASM
You may also use the ASM_DISKSTRING to limit what Oracle is allowed to see.
It is recommended to create soft links so that you can easily move the disk devices around more easily.
e.g.
mkdir /dev/asm
ln -s /dev/dsk/c1t1d0 /dev/asm/disk1
ln -s /dev/dsk/c1t1d1 /dev/asm/disk2
...
ASM_DISKSTRING=/dev/asm
I can't find the white paper which contains all the recommendation. If you have metalink access, please check for it.
hope this helps too!
kind regards

Re: oracle 10g and ASM
the white papers for ASM can be found on OTN :
http://www.oracle.com/technology/products/database/asm/index.html
as mentioned, use asm_diskstring to limit the pool of disks available to ASM.
