Using udev devices for ASM disk on Linux
Hello all,
I need details related to using udev devices as ASM disk on Linux.
What I want to know is, once i get the list of ASM Disks that are used to create the DiskGroups, based on the path of the Disk (whether /dev/sdj or /dev/dm-3 or /dev/asm_udev_device, /dev/vx/<vxvm-volume>, /dev/<lvm-volume>) how do i get to know if the device type is a udev device?
I want to know an automated process, so that i can script it out to separate out each device easily.
Please let me know if anyone has expertise on using udev devices with Oracle ASM.
I have referred the link but no much details available http://www.oracle.com/technology/products/database/asm/pdf/device-mapper-udev-crs-asm%20rh4.pdf
Further, the behavior of udevinfo command is very different across version of Linux. From Suse 10 onwards, udevadm has to be used instead.
Its confusing to me.
Please help.
