Sorry ... we have no way of knowing a user's background, and when you said "i dont understand what A13 is", I - fairly - made the assumption that your experience with hardware was very limited. Have you upgraded/replaced the processors, or are these the ones that came from the factory? Either way, 1.2.0 is VERY old and you risk this and other issues keeping it at this level.  I would strongly recommend updating your system firmware (BIOS, ESM/BMC, backplane, RAID, HDD, NIC, DRAC). Since you are running ESX, you will need to update outside of the OS: Download the following ISO and create a DVD using the image (SBUU - Systems Build and Update Utility) - it contains the mechanism used to update firmware outside of the OS:[URL] Download the following ISO's and create a DVD using the final image (SUU - Server Update Utility - pay particular attention to the Installation Instructions on the download page for each ISO image) - it contains the repository of updates to be used with SBUU:[URL] You will first boot to SBUU, choose Update Fimware, then when you are prompted for the update repository, you insert the SUU media.  It will update all your firmware at once.
