What device path do you have to specify in ASM, if you want to use the multipath device?
/dev/sdd = first path
/dev/sdd = second path
/dev/multipatha = path of the multipath OS driver
A.
Only /dev/sdc is enough, because asmlib knows it is a multipath device.
B.
/dev/sdc as disk group and /dev/sdd as failure group.
C.
You need to specify all the three devices and only then ASM will know this is a multipath device.
D.
Only /dev/multipatha is enough.
