How unallocated space of hard drive can be used as raw device to install asm?
let us say we have hard drive of 100GB among which i have created partitions of 50 GB
and installed Red hat linux,
and remaining 50gb hard disk is not touched ie unallocated, so i would like to use this unallocated
space to be used as raw device by Operating System in order to install and configure ASM, please suggest..
The high level steps are:
1. install ASMLIB
2. use ASMLIB to create ASM disk from raw device /dev/sdaX
3. install Grid Infrastructure software
4. create ASM instance
5. create ASM diskgroup using ASM disks configured in ASM instance
