Environment: Oracle 10gR2 (10.2.0.5) + ASM
Platform: RHEL 5.8 64-bit
I am configuring ASM Disk groups on a brand new ASM installation. I am confused what should I use for the "Disk Discovery Path" value?
Both options give me list of the devices that have been configured. The RHEL Sys Admin mentioned that if a new device is added to any of the controllers, the device names under "/dev/sd*" will change (e.g., /dev/sdd may become /dev/sde) which can make ASM corrupt - whereas the values under "/dev/disk/by-path/*" will NEVER change. I am not using ASMLib.
I wonder which one should I use as "Disk Discovery Path" (I believe this will become value for ASM_DISKSTRING parameter)?
