Citrix Systems 6 Host-emergency-management-reconfigure, Host-enable, Host-evacuate, Host-forget

Get a Xen dmesg (the output of the kernel ring buffer) from specified XenServer hosts.

The host(s) on which this operation should be performed are selected using the standard selection mechanism (see host selectors above). Optional arguments can be any number of the host parameters listed at the beginning of this section.

host-emergency-management-reconfigure

host-emergency-management-reconfigure interface=<uuid_of_management_interface_pif>

Reconfigure the primary management interface of this XenServer host. Use this command only if the XenServer host is in emergency mode, meaning that it is a member in a resource pool whose master has disappeared from the network and could not be contacted for some number of retries.

host-enable

host-enable[<host-selector>=<host_selector_value>...]

Enables the specified XenServer hosts, which allows new VMs to be started on them.

The host(s) on which this operation should be performed are selected using the standard selection mechanism (see host selectors above). Optional arguments can be any number of the host parameters listed at the beginning of this section.

host-evacuate

host-evacuate[<host-selector>=<host_selector_value>...]

Live migrates all running VMs to other suitable hosts on a pool. The host must first be disabled using the host- disable command.

If the evacuated host is the pool master, then another host must be selected to be the pool master. To change the pool master with HA disabled, you need to use the pool-designate-new-mastercommand. See the section called “pool-designate-new-master”for details. With HA enabled, your only option is to shut down the server, which will cause HA to elect a new master at random. See the section called “host-shutdown”.

The host(s) on which this operation should be performed are selected using the standard selection mechanism (see host selectors above). Optional arguments can be any number of the host parameters listed at the beginning of this section.

host-forget

host-forgetuuid=<XenServer_host_UUID>

The xapi agent forgets about the specified XenServer host without contacting it explicitly.

Use the --forceparameter to avoid being prompted to confirm that you really want to perform this operation.

Warning:

Do not use this command if HA is enabled on the pool. Disable HA first, then enable it again after you've forgotten the host.

Tip:

This command is useful if the XenServer host to "forget" is dead; however, if the XenServer host is live and part of the pool, you should use xe pool-ejectinstead.

host-get-system-status

host-get-system-status filename=<name_for_status_file>

[entries=<comma_separated_list>] [output=<tar.bz2 zip>] [<host-selector>=<host_selector_value>...]
