When you connect directly to an ESXi host with the vSphere Client, you can perform a variety of configuration tasks such as setting the scratch partition, redirecting the direct console, and configuring syslog. Reboot or Shut Down an ESXi HostYou can power off or restart (reboot) any ESXi host using the vSphere Client. Powering off a managed host disconnects it from vCenter Server, but does not remove it from the inventory. Redirect the Direct Console to a Serial Port by Using the vSphere ClientYou can redirect the direct console to either of the serial ports com1 or com2. When you use the vSphere Client to redirect the direct console to a serial port, the boot option that you set persists after subsequent reboots. Set the Scratch Partition from the vSphere ClientIf a scratch partition is not set up, you might want to configure one, especially if low memory is a concern. When a scratch partition is not present, vm-support output is stored in a ramdisk. Configure Syslog on ESXi HostsAll ESXi hosts run a syslog service (vmsyslogd), which logs messages from the VMkernel and other system components to log files. Set the Host Image Profile Acceptance LevelThe Host Image Profile acceptance level determines which vSphere installation bundles (VIBs) are accepted for installation.
