Citrix Systems 6 Host-restore, Host-set-hostname-live, Host-shutdown, Host-syslog-reconfigure

Reboot the specified XenServer hosts. The specified hosts must be disabled first using the xe host-disablecommand, otherwise a HOST_IN_USE error message is displayed.

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.

If the specified XenServer hosts are members of a pool, the loss of connectivity on shutdown will be handled and the pool will recover when the XenServer hosts returns. If you shut down a pool member, other members and the master will continue to function. If you shut down the master, the pool will be out of action until the master is rebooted and back on line (at which point the members will reconnect and synchronize with the master) or until you make one of the members into the master.

host-restore

host-restore[file-name=<backup_filename>][<host-selector>=<host_selector_value>...]

Restore a backup named file-nameof the XenServer host control software. Note that the use of the word "restore" here does not mean a full restore in the usual sense, it merely means that the compressed backup file has been uncompressed and unpacked onto the secondary partition. After you've done a xe host-restore, you have to boot the Install CD and use its Restore from Backup option.

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-set-hostname-live

host-set-hostnamehost-uuid=<uuid_of_host>hostname=<new_hostname>

Change the hostname of the XenServer host specified by host-uuid. This command persistently sets both the hostname in the control domain database and the actual Linux hostname of the XenServer host. Note that hostname is not the same as the value of the name_label field.

host-shutdown

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

Shut down the specified XenServer hosts. The specified XenServer hosts must be disabled first using the xe host- disable command, otherwise a HOST_IN_USE error message is displayed.

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.

If the specified XenServer hosts are members of a pool, the loss of connectivity on shutdown will be handled and the pool will recover when the XenServer hosts returns. If you shut down a pool member, other members and the master will continue to function. If you shut down the master, the pool will be out of action until the master is rebooted and back on line, at which point the members will reconnect and synchronize with the master, or until one of the members is made into the master. If HA is enabled for the pool, one of the members will be made into a master automatically. If HA is disabled, you must manually designate the desired server as master with the pool-designate-new-mastercommand. See the section called “pool-designate-new-master”.

host-syslog-reconfigure

host-syslog-reconfigure[<host-selector>=<host_selector_value>...]

Reconfigure the syslog daemon on the specified XenServer hosts. This command applies the configuration information defined in the host logging parameter.
