Assuming this is some sort of linux, you can follow a procedure to rescan the drive, see the new space, and increase the filesystem. It might vary from distro to distro, though, so you might need to look at the documentation.

the only thing you need to do after you resized the luns in your storage is, echo 1 > /sys/block/<subpath>/device/rescan for every subpath of emcpowera

Now you need to tell to your server, the size of /dev/emcpowera has changed, use sfdisk -R /dev/emcpowera

If you are using /dev/emcpowera as physical volume, use pvresize /dev/emcpowera, after this you can resize your logical volume and the filesystem
