Re: Questions re ASMLib on Linux

Bill,
answers are no and no.
The main use that I found for ASMLIB is that it gives you the ability to easily remap devices after a reboot. Sometimes, if you have a NAS, when you reboot your NAs and server, devices (i.e. /dev/sd....) may not be the same as before reboot (i.e. what was /dev/sdc may become /dev/sdd). In this case, you may not be able to have the proper raw devices assigned, and hence end up with your CRS and ASM not coming up (ASMLIB does not solve the problem for CRS, it does for ASM).
you have to configure the devices yourself (/etc/init.d/oracleasm .....)
