It wasn't cable or HBA issue from the host.

I ended up calling EMC support and was able to resolve
it by traspass the lun to different SP port. And the
host immediately see the lun right away.

Apparently after the reboot of the EMC, the lun got to
switch to different SP Port.

Thanks again to all.
