But what is it? When you do your LUN creation and storage group work so that you now have real disk(s) presented to the host, just rmdev -dl hdiskx for each of the LUNZ, and Because it is neither part of the initscripts nor the PowerPath package, it survives updates of both the kernel and PowerPath:
#! /bin/sh # Chkconfig compliant PowerPath start script # chkconfig: Find the Infinity Words! weblink
Run syminq and see if you see all the devices via hdiskX and hdiskpowerXX I would say you can modify this and remove the second hba from powerpath and system but If you like my ideas, will you buy me coffee?

But I tried running as root, hoping things would be different as super-user but that was not the case. RHEL6.3 document suggests using '1 alua' to support Clarrion/VNX storage instead of '1 emc' which they claim legacy (PNR) driver. In this case I will have to complete the migration quickly and get rid of dependencies on the old Clariion. this content The first tipshown in the output : “Add _netdev to /etc/fstab mount options for PowerPath pseudo devices.” have no meaning in hardware Fibre Channel configuration (but ok for software iSCSI devices),
