o After you upgrade all of your hosts to ESX4/ESXi4, you can optionally uninstall your license server and remove the license server configuration
from vCenter Server.
o For ESXi, the vSphere Host Update Utility does not support roll back.
o You can remove the ESX 4.0 boot option from the ESX bootloader menu and perform a complete roll back to ESX 3.x. Any changes made to
the ESX 4.0 service console are lost after the rollback.
o Any changes made to VMs will persist after the rollback.
o If you upgraded the VM hardware, 220 702 the VMs will not work after you perform the ESX rollback. To avoid this situation, take a snapshot of
the VM before you upgrade the VM hardware.
o Run the rollback-to-esx3 command – reconfigures the bootloader.
o Reboot the server.
o After the host boots into ESX 3.x, delete the ESX 4.0 service console VMDK folder from the VMFS datastore.
o Each time you update an ESXi host, a copy of the ESXi build is saved on your host.
o ESXi permits only one level of rollback.
o When you manually boot into the standby build instead of the current boot build, an irreversible rollback occurs.
o When the page that displays the current boot build appears, press Shift+r to select the standby build.
o Do not use vmware-vmupgrade.exe to upgrade VMs.
o Some VMs that you create on ESX4 hosts are supported on ESX 3.x/ESXi 3.5 hosts. If you create a VM on ESX4 and select the typical path, the
virtual hardware version is version 7. Virtual machines with virtual hardware version 7 are not supported on ESX 3.x/ESXi 3.5 hosts. Select the
custom path and select virtual hardware version 4
o If you create VMs that use paravirtualization (VMI) or an enhanced networking device (vmxnet), VMotion is not supported. In this case, you
can only move the VM to the ESX 3.x host if the VM is powered off.
o On Windows guest operating 9L0-403 systems, you must reboot the VM a total of three times when you upgrade VMware Tools and the virtual
hardware:
1. Power on the VM.
2. Upgrade VMware Tools.
3. Reboot the VM at the end of the VMware Tools upgrade.
4. Power off the VM.
5. Upgrade the virtual Hardware.
6. Power on the VM.
7. The Windows operating system detects new devices and prompts you to reboot the VM.
8. Reboot the VM to make the devices work properly.
o During the virtual hardware upgrade, the VM must be shut down for all guest operating systems.
o When you upgrade from virtual hardware version 3 to version 7, the upgrade is irreversible, even if you take a VM backup or snapshot before
performing the upgrade. 4 to version 7 the upgrade is reversible if you take a VM backup or snapshot
o Tools for installing updates and patches to ESX/ESXi hosts:
o Host Update Utility – graphical utility for ESXi only.
o Update Manager – for ESX and ESXi,
o vihostupdate – command-line utility for ESX and ESXi.
o esxupdate – command-line utility for ESX only.
o If the Host Update Utility does not meet the needs of your environment, you can customize the application the settings.config XML file,
located in %PROGRAMFILES%\VMware\Infrastructure\VIUpdate 4.0
o Run vihostupdate on ESX 4.0/ESXi 4.0 hosts. Run vihostupdate35 on ESX 3.5/ESXi 3.5 hosts.
o The esxupdate utility is supported as well. It is for ESX only.
o The vihostupdate command works with bulletins.
o You can use the vihostupdate utility in conjunction with offline bundles or with a depot.
o To get the build number of an ESX4 host: # vmware –l (from KB 1001179).

VCP-410 Test Questions
o Back up the VirtualCenter 2.x SSL certificates. %ALLUSERSPROFILE%\Application Data\VMware\VMware VirtualCenter or
%ALLUSERSPROFILE%\VMware\VMware VirtualCenter\.
o Note any non-default settings, such as the IP address, the database DSN, user name, password, and assigned ports.
o Create a backup copy of vpxd.cfg.
o The database upgrade log is at %TEMP%\VCDatabaseUpgrade.log.
o By default, a vCenter Server 220 701 creates a maximum of 10 simultaneous database connections.
o Datastores and networks have their own set of privileges that control access to them.
o Users are initially granted the No Access role on all new managed objects, including datastores and networks. All existing objects in vCenter
maintain their permissions after the upgrade.
o The upgrade process uses the datacenter's “Read-only” privilege.
o If the “Read-only” privilege is nonpropagating (not inherited by child objects), VMware assumes access privileges should not be assigned
to datastores and networks.
o If the “Read-only” privilege is propagating (inherited by child objects), VMware assumes access privileges should be assigned to
datastores and networks so users can view them and perform basic operations that require access.
o The “Read-only” propagating permission on a datacenter, as well as all other permissions you have set, will continue to work as expected after
the upgrade.
o You must change “Read-only” nonpropagating datastore permissions to propagating datastore permissions in order for users to access the
datastore. You can assign datastore permissions on datastore or folders containing datastore. The same goes for Network permissions.
o The “Database Consumer” sample role assigns the “Allocate Space” privilege to the datastore. “Network Consumer” sample role assigns the
“Assign Network” privilege.
o Host Update Utility does not upgrade VMFS datastores or VM
o Update Manager supports mass remediation.
o During host upgrades using the Update Manager, static IP addresses are a requirement.
o The upgrade to ESXi4 & ESX4 preserves almost all configuration data, including your networking, security, and storage configuration. The only
configuration not preserved is related to licensing.
o For ESX only, the upgrade reuses the existing /boot partition to hold the ESX 4.0 boot files. After the upgrade, the ESX 3.x installation is
mounted in the new ESX 4.0 220 702 installation under the /esx3-installation directory.
o Backup the ESX Host Configuration:
o Back up the files in the /etc/passwd, /etc/groups, /etc/shadow, and /etc/gshadow directories.
o Back up any custom scripts.
o Back up your .vmx files.
o Back up local images, such as templates, exported VMs, and .iso files.
o Backup the ESXi Host Configuration: vicfg-cfgbackup --server --portnumber --
protocol --username username --password -s
o You cannot perform an in-place upgrade from ESX to ESXi (or from ESXi to ESX).
o The only ESX 2.x version that has upgrade support is ESX 2.5.5 – you can perform a migration upgrade with or without VMotion.
o Direct, in-place upgrade from ESX 2.5.5 to ESX 4.0 is not supported, even if you upgrade to ESX 3.x as an intermediary step. The default ESX
2.5.5 installation creates a /boot partition that is too small to enable upgrades to ESX 4.0. As an exception, if you have a non-default ESX 2.5.5
installation on which at least 100MB of space is available on the /boot partition, you can upgrade ESX 2.5.5 to ESX 3.x and then to ESX 4.0.
o The upgrade logs are here:
o /esx3-installation/esx4-upgrade/
o /var/log/vmware/
o For an unsuccessful ESX upgrade:
o /esx4-upgrade/
o /var/log/vmware/
o You may need to reconnect the host to vCenter Server and assign an upgraded license to your product within 60 days after the upgrade.
o The host sdX devices might be renumbered after the upgrade.
o You must convert LUN masking 220 701 to the claim rule format. Run the esxcli corestorage claimrule convert command. It converts
the /adv/Disk/MaskLUNs advanced configuration entry in esx.conf to claim rules with MASK_PATH as the plug-in.
o Web Access service is disabled after you upgrade the host.
o vSphere Web Access is not supported on ESXi hosts.
o 60-day evaluation count down starts even if the host is licensed and you are not using evaluation mode.
o One advantage of using evaluation mode is that it offers full feature functionality.
o After you determine that the ESX 4.0 upgrade is stable, you can remove the ESX 3.x boot option from the ESX 4.0 bootloader menu to disable
the ability to roll back to ESX 3.x. If you deselected the rollback option, this procedure is not applicable. Run the cleanup-esx3 command
with the optional -f (force) flag.
o The cleanup-esx3 script removes the following files and references from the ESX 4.0 host:
o ESX 3.x references in the /etc/fstab directory
o ESX 3.x boot files in the /boot directory
o The rollback-to-esx3 script in the /usr/sbin/ directory
Testking VCP-410
o When you restore the standard switch, a new virtual adapter is created and the management network uplink that is currently connected to
vNetwork Distributed Switch is migrated to the new virtual switch.
o The software creates these partitions:
o One 4GB VFAT scratch partition for system swap.
o One VMFS3 partition on the remaining free space.
o The installer creates a 110MB vcp 4 diagnostic partition for core dumps.
o The scratch partition is not required (but created by default during the installation). It is used to store vm-support output, which you need
when you create a support bundle.
o Lockdown mode prevents remote personnel from logging in to the ESXi host by using the root login name. By default, lockdown mode is
disabled.
o Resetting the configuration does not remove virtual machines on the ESXi host. After you reset the configuration defaults, the virtual
machines are not visible, but you can retrieve them by reconfiguring storage and reregistering the virtual machines.
o When you perform a configuration backup, the serial number is backed up with the configuration and is restored when you restore the
configuration. The serial number is not preserved when you run the Recovery CD (ESXi Embedded) or perform the repair operation (ESXi
Installable).
o When you restore the configuration, the target host must be in maintenance mode, which means all virtual machines (including the vSphere
CLI virtual appliance) must be powered off.
o Run the vicfg-cfgbackup command with the -s flag to save the host configuration to the specified backup filename.
o When you restore configuration data, the build number currently running on the host must be the same as the build number that was running
when you created the backup file. You can override this requirement by including the -f (force) flag with the vicfg-cfgbackup
command.
o Run the vicfg-cfgbackup command with the -l flag to load the host configuration from the specified backup file.
o You can restore the ESXi Installable software by running the ESXi installation CD in repair mode. All host configuration data is overwritten by
system defaults.
o During the repair operation, your vmware vcp 4 existing ESXi 4.0 Installable VMFS datastore is preserved if it is in its original location on the ESXi 4.0 boot
disk, or if it is located on another disk (separate from the boot disk). If you changed the VMFS location on the boot disk, it is preserved if it is
located beyond the 900MB partition.
vSphere upgrade guide
o When you upgrade from ESX 3.x/ESXi 3.5 to ESX 4.0/ESXi 4.0, you can use either the vSphere Host Update Utility or vCenter Update Manager.
o EDIT – you can also use the upgrade script (esxupgrade.sh – KB 1009440). VMware doesn’t mention the option of a fresh install at any point;
they are pushing the upgrade option as much as possible. You can’t seem to do an upgrade with the ESX4 install CD.
o Host Update Utility is used for upgrading ESX 3.x/ESXi 3.5 standalone hosts to ESX 4.0/ESXi 4.0 and for patching ESXi 4.0 standalone hosts. It is
a standalone Microsoft Windows application recommended for smaller deployments with fewer than 10 ESX/ESXi hosts, without vCenter
Server or Update Manager.
o vCenter Update Manager is for upgrading and updating ESX/ESXi hosts that are managed in vCenter Server.
o Orchestrated upgrades can be used to upgrade the VM hardware and VMware Tools.
o No VMFS upgrade is required if you are upgrading from ESX 3.x
o You must upgrade VMware Tools before upgrading virtual hardware.
o After you upgrade to vCenter Server, you cannot revert to VirtualCenter 2.x. Take appropriate backups before starting the upgrade.
o Upgrade VirtualCenter 2.x to vCenter Server 4.0:
o Make sure your database is compatible
o Have required permissions
o Take a full backup of the VirtualCenter 2.x database
o Back up the VirtualCenter 2.x SSL certificates
o Install the vSphere Client
o vCenter Converter, upgrade

server to manage ESX 3.x/ESXi 3.5 hosts.
o If a vCenter Server license expires, the managed hosts become disconnected.
o If an ESX/ESXi host license expires, the VMs that reside on the host continue to run, but you cannot power on the VMs or reset them.
ESXi Installable and vCenter Server Setup Guide
o When you power on the ESXi host for the first time or after resetting the configuration defaults, the host enters an autoconfiguration phase
during which system network and storage devices are configured with defaults.
o By default, DHCP configures IP and all visible blank internal disks are formatted with VMFS so that virtual machines can be stored on the disks.
o ESXi has an interface called the vmware vcp 410 direct console to:
o Configuring host defaults
o Setting up administrative access
o Troubleshooting
o Minimum hardware configurations supported by ESXi 4.0:
o 64-bit x86 CPUs.

VCP-410 Dumps
Introduction to VMware vSphere
o vCompute – aggregate resources
o vStorage – enables the most efficient use and management of storage
o vNetwork – simplify and enhance networking
o Fault Tolerance – a secondary copy. Actions completed on the primary VM are also applied to the secondary VM. If the primary VM becomes
unavailable, the secondary machine becomes active, providing continual availability.
o Distributed Virtual Switch (DVS) – VCP-410 exam questions spans many hosts reduction of maintenance and increasing network capacity.
o Host Profiles – host configuration management through user-defined configuration policies. Captures the blueprint and monitors compliance.
o Pluggable Storage Array (PSA) – greater array certification flexibility and improved array-optimized performance. A multipath I/O framework.
o Cluster – aggregate computing and memory resources of a group of physical x86 servers sharing the same network and storage arrays.
o Resource pools – partitions of computing and memory resources from a single host or a cluster. can be hierarchical and nested.
o Storage VMotion – enables the migration of VMs from one datastore to another datastore without service interruption
o Fault Tolerance (FT) – uses vLockstep technology, continuous availability by protecting a VM (the Primary VM) with a shadow copy (Secondary
VM) that runs in virtual lockstep on a separate host.
o vNetwork Distributed Switch (dvSwitch) – functions as a single virtual switch across all associated hosts.
o dvPort (distributed virtual port) – a port on a DVS that connects to a host’s service console or VMkernel or to a VM’s network adapter.
o vApp – has the same basic operation as a VM, but can contain multiple VMs or appliances.
o Web Access cannot be used to access a host running ESXi 4.0.
o Web Access is turned off by default for ESX hosts.
Getting Started with ESX
o ESX Service Console is held in the esxconsole.vmdk partition.
o vCenter Server uses Microsoft SQL Server 2005 Express for small deployments with up to 5 hosts and 50 VMs.
o If SQL Native Client is already installed, uninstall SQL Native Client before you begin the vCenter Server installation.
o vCenter server must belong to a domain rather VCP-410 study guide than a workgroup. Otherwise it’s not able to discover – using such features as vCenter Guided
Consolidation Service. The computer name cannot be more than 15 characters.
o vCenter Server cannot be an Active Directory domain controller.
o The Domain user account should have the following permissions:
o Member of the Administrators group
o Act as part of the operating system
o Log on as a service
ESX and vCenter server installation guide
o ESX4 will only install and run on servers with 64-bit x86 CPUs. They require a 2GB RAM minimum.
o vCenter Server must have 2 CPUs and 3GB RAM.
o The vCenter Server has a service called VMware VirtualCenter Management Webservices. This service requires 128MB to 1.5GB of additional
memory.
o You can use a 32-bit Windows for up 200 hosts. A 64-bit Windows can have 200-300 hosts.
o The vSphere Client requires the Microsoft .NET 3.0 SP1 Framework.
o vCenter server required firewall ports:
Port Description
80 Redirects requests to HTTPS port 443.
389 LDAP port number for the Directory Services for the vCenter Server group. Needs to bind to port 389, even if you are not joining this
vCenter Server instance to a Linked Mode group.
443 Listen for connections from the vSphere Client.
636 For vCenter Linked Mode, this is the SSL port of the local instance
902 Uses to send data to managed hosts. VCP-410 questions Managed hosts also send a regular heartbeat over UDP port 902 to the vCenter
902/903 Ports used by vSphere Client to display VM consoles.
8080 Web Services HTTP. Used for the VMware VirtualCenter Management Webservices.
8443 Web Services HTTPS. Used for the VMware VirtualCenter Management Webservices.
o If ESX will not use an NTP server, make sure that the server hardware clock is set to UTC in the BIOS (EDIT: As a matter of best practice you
should always set ESX server’s hardware clocks to UTC)
o IPv6 is not supported for ESX installation
o The service console must be installed on a VMFS datastore that is resident on a host's local disk or on a SAN disk that is masked and zoned to
that particular host only.
