Powerpath and ASM w/o ASMLib

We are changing SANs from an EMC VNX to an EMC UNITY. The servers and SANs are hosted at a third-party site. We are on RHEL 6.8. We are not using ASMLib.

When I was informed that the LUNs had been presented to the servers (it's a 2-node RAC) I re-scanned the hosts and the Powerpath devices showed up. Using parted I partitioned each LUN as a full primary partition. I added the WWID to udev rules, but no matter what I try, the LUNs are not showing up in the ASM search path. Generally I don't use Powerpath, so I'm hoping I don't have to reboot the server to get these to show up.

*Here's what I see (using one LUN as an example):*

*[root_at_685925-db6 dev]# ls -al |grep emcpowereebrw-rw---- 1 root disk

*Here's the stanza in /udev/rules.d/99-oracle-grid.rules:*

I've tried rescanning the host(s), /sbin/udevadm control --reload-rules with /sbin/udevadm trigger --type=devices --action=change and powermt save and powermt config.

Nothing.

Do I need to reboot or is there some way to get these to show up?
