Best Answer
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 ofemcpowera
Now you need to tell to your server, the size of
/dev/emcpowera
has changed, usesfdisk -R /dev/emcpowera
If you are using
/dev/emcpowera
as physical volume, usepvresize /dev/emcpowera
, after this you can resize your logical volume and the filesystem
