EMCPower path configuration


Customer upgraded to product version 6.0RP1HF2
-- EMC recommendation:
Solution given:  Use format -e to force the label of the device and the creation of the specific "wd" slice) is working;

 Or use the following workaround:  Change the failover mode on the Clariion from 1 to 4 (ALUA). It is supported by Oracle, VxVm and PowerPath ... and this should address the issue ... if this is really the issue Oracle is suggesting (wrong information coming from the passive path).

Note that after changing the failover mode to 4, reboot is required with reconfiguration flag for the change to be taken into account (reboot -- -r).
