I installed EMCpower.LINUX-6.0.0.00.00-158.el6.x86_64 on RHEL7, register it. but when initiate "#powermt display", it returns Device(s) not found.

Also installed QLogic-SuperInstaller-REL2015U1-20150630-6, and HBA is loaded on kernel.

I'm assuming you've disabled the built-in multipathing software (multipathd)?

You should install the sg3_utils package if you have not done so already ( yum -y install sg3_utils )... this will allow you to issue the command rescan-scsi-bus.sh, which scans the bus and issues a LIP. You should then be able to see the paths in powermt display.

If not, download and install 'inq' from EMC support and see if you can see the luns in there.

Good article on online storage reconfiguration in RHEL here:

Info on the sg3_utils usage here:
