How to add disks to existing ASM disk group in 11gR2

Here I am going to show you how to add new disks( or extra space/storage) to the existing ASM diskgroups.

Given:

Unix SA has provided/presented the new raw devices with the same size as the existing disks in our ASM disk group.


here my asm discovery path or the location where the new disks have been presented is
"/dev/oracle/"

given/need to add the six new disks:
crw------- 1 oracle oinstall 302, 42061 Dec 8 14:59 disk64g_t1_0028
crw------- 1 oracle oinstall 302, 42062 Dec 8 14:59 disk64g_t1_0029
crw------- 1 oracle oinstall 302, 42063 Dec 8 14:59 disk64g_t1_0030
