Re: ASM and EMC PowerPath

Thank you!
I'm already reading all the notes I was able to find on MOS and google (including the below mentioned Configuring Oracle ASMLib on Multipath Disks on Linux).

I was only unsure on what to do, given that the disks that are already configured point to the physical paths
and the fact that this is a live production database.

I doubt that we can change the paths of all disks online, could we?

1. Set ORACLEASM_SCANEXCLUDE to "sd"
2. oracleasm scandisks on all nodes.

I suppose we need to stop all asm and client db instances.

Best regards
Dimitre
