Red Hat

I'd be a little surprised if it doesn't handle multipath devices and associate them to form just the devices you need. What would happen if someone later decided to overwrite /dev/sdf because it looks to be free?

At first glance, the proposed commands looks fine to me although personally I would use a more human name for the volume group & logical volume, such as vg_oracle and lv_oradata.

Your mkdir doesn't force it to create the directory in the root directory though, so you might need to check that. You need to be consistent with your device names too. Are you using /dev/sdc or /dev/sdd? What's wrong with /dev/sdb anyway? That looks to be over 500Gb of unused disk.

As I said initially I do not have skills on redhat, so because I did not set-up this server, I am not to keen on touching something that I did not do /dev/sdb!, so I will follow your advice and create the volume group.


Thanks for your help
