= ESXi 5.1 Post Install = **Summary**: This is a list of steps you should perform after installing or upgrading an host to ESXi 5.1. \\ **Date**: Around 203 \\ **Refactor**: 21 February 2025: Checked links and formatting. \\ {{tag>vmware}} == Configure Syslog == See [[syslogesxi]] for configuring syslog. == Configure the Guest Clipboard == Add these two lines to /etc/vmware/config file:


isolation.tools.copy.disable="FALSE"
isolation.tools.paste.disable="FALSE"

== RDM Settings == If the host will have VMs that participate in MSCS set the perenially reserved option explained in [[rdmsettings]]. == ALUA and RoundRobin == To make sure the host uses optimized paths make sure ALUA is enabled on the host and that all MPP policies are set to round robin. This is explained in [[alua]]. == NTP Settings == Make sure to set the NTP settings in Configuration -> Time Configuration: * Set the NTP server * Set the Startup policy to start and stop with the host == Increase vSwitch Port Numbers == If you have big hosts who can handle a lot of guests make sure to change the number of ports on the vSwitches to a higher number (for example 248). This is a setting for which ESXi will have to reboot, so: * Go to Configuration -> Networking * Select vSwitch0 and click on properties * Edit the vSwitch and set the number of ports to 248 * Save the settings and reboot the host == Scratch Partition == If your host is running from usb storage you also need a scratch partition for logging purposes, see [[esxiscratch|here]]. == Increase VMFS Heap Size == If the host will run a large number of VMs increase the size of the VMFS Heap size so the host can handle more then the default of 8 TB on open VMDK disks: * Go to the Configuration tab -> Advanced Settings. * Click VMFS3. * Update the field in VMFS3.MaxHeapSizeMB from 80 to 256 MB * Reboot the host for the changes to take affect. The new setting will allow for 25 TB on open VMDK files. //This wiki has been made possible by://
