We are running Centos 6.7 - 2.6.32-573.22.1.el6.x86_64 on a Quanta 
Cirrascale, up to date with patches. We have had a couple of instances 
in which the hard drives have become renamed after reboot (e.g. drive 
sda is renamed to sdc after reboot).  One time this occurred when we 
rebooted following the installation of a 10GB NIC card, another time 
after we tried to install mellanox drivers 
(MLNX_OFED_LINUX-3.2- Currently we are unable to 
boot because that drive has been renamed.

Our questions are

  * Has anyone else experienced similar issues?
  * What can we do to prevent such renaming in the future
