NAME

       vzmigrate - migrate a container between two OpenVZ servers

SYNOPSIS

       vzmigrate [-r|--remove-area yes|no] [--ssh=ssh_options] [--rsync=rsync_options] [--keep-dst] [--online] [-v] destination_address CTID

DESCRIPTION

       This  utility  is  used	to  migrate  a container from one (source) Hardware Node (HN) to another (destination) HN. The utility can migrate
       either stopped or running container. For a stopped container, simple CT private area transfer is  performed  (rsync(1)  is  used  for  file
       transfer). For running containers, migration may be offline (default) or online.

       This  program uses ssh as a transport layer. You will need to put ssh public key to destination node and be able to connect to node without
       entering password.

OPTIONS

       -r, --remove-area yes | no
	      Whether to remove a container area on source HN for the successfully migrated container. Default is yes.

       --ssh=options
	      Additional options that will be passed to ssh while establishing connection to destination HN.

       --rsync=options
	      Additional options that will be passed to rsync(8).  You may add options like -z to enable data compression  if  you  are  migrating
	      over a slow link.

       --keep-dst
	      Do  not  clean  synced  destination container private area in case of some error. It makes sense to use this option on big container
	      migration to avoid syncing container private area again in case some error (on container	stop  for  example)  occurs  during  first
	      migration attempt.

       --online
	      Perform  online (zero-downtime) migration: during the migration the container hangs for a while and after the migration it continues
	      working as though nothing has happened.

       -v     Verbose mode. Causes vzmigrate to print debugging messages about its progress.  Multiple -v options  increase  the  verbosity.   The
	      maximum is 3.

EXAMPLES

       Migration of CT 101 to 192.168.1.130 with downtime:

	  vzmigrate 192.168.1.130 101

       Online migration of CT 102 to 192.168.1.130:

	  vzmigrate --online 192.168.1.130 102

EXIT STATUS

       0 EXIT_OK
	      Command completed successfully.

       1 EXIT_USAGE
	      Bad command line options.

       2 EXIT_VE_STOPPED
	      Container is stopped.

       4 EXIT_CONNECT
	      Can't connect to destination (source) HN.

       6 EXIT_COPY
	      Container private area copying/moving failed.

       7 EXIT_VE_START
	      Can't start or restore destination CT.

       8 EXIT_VE_STOP
	      Can't stop or checkpoint source CT.

       9 EXIT_EXISTS
	      Container already exists on destination HN.

       10 EXIT_NOTEXIST
	      Container does not exists on source HN.

       12 EXIT_IP_INUSE
	      You attempt to migrate CT which IP address(es) are already in use on the destination node.

       13 EXIT_QUOTA
	      Operation with CT quota failed.

NAME

       prtfru - print FRUID-specific information about the FRUs on a system or domain

SYNOPSIS

       /usr/sbin/prtfru  [-d] | [-clx] [container]

DESCRIPTION

       The  prtfru  utility is used to obtain FRUID data from the system or domain. Its output is that of a tree structure echoing the path in the
       FRU (Field-Replaceable Unit) tree to each container. When  a container is found, the data from that container is  printed  in  a  tree-like
       structure as well.

       prtfru  without	any arguments will print the FRU hierarchy and all of the FRUID container data. prtfru prints to stdout which may be redi-
       rected to a file.

OPTIONS

       The following options are supported:

       -c	Prints only the containers and their data. This option does not print the FRU tree hierarchy.

       -d	Prints a DTD for the current registry to stdout.

       -l	Prints only the FRU tree hierarchy. This option does not print the container data.

       -x	Prints in XML format with a system identifier (SYSTEM) of prtfrureg.dtd.

       Options -c and -l can be used together to obtain a list of the containers.

OPERANDS

       The folowing operand is supported:

       container       The name of a particular container in the FRU hierarchy, that is, either the name or path/name of a container as  displayed
		       in the -l option.

EXIT STATUS

       The following exit values are returned:

       0	All information was found and printed successfully.

       >0	An error has occurred.
