It is related to Check Point MGMT VM with R80.10 in my story, but you would as well want to resize Check Point gateway firewall hardware box or VM.
I was searching for a simple solution and found different ones that didn’t work for me, so here are the steps that you need to go through when you resize your CheckPoint VM disk in vCenter and then need to expand the partition inside Check Point VM in order to use the additional space.
Of course, you did choose too small HDD for your VM when you created it and now you cannot upload some hotfixes or vSEC gateway files to it because you don’t have enough space.
Get to vCenter and shut down the VM.
Get more GB to your VM and power it back up.
