|
||||
[-P|--scripts [script1,script2...]]
|
||||
|
||||
I<noderange> is a list of nodes and node groups.
|
||||
B<updatenode> <noderange> [-V|--verbose] [script1,script2...]
|
||||
|
||||

=head1 OPTIONS
|
||||
=head1 B<DESCRIPTION>
|
||||
|
||||
B<-h | --help> Display usage message.
|
||||
The updatenode command is run on the xCAT management node and can be used
|
||||
to perform the following node updates:
|
||||
1) Distribute and synchronize files.
|
||||
2) Install or update software on diskfull nodes.
|
||||
3) Re-run postscripts.
|
||||
|
||||
B<-v | --version > Command Version.
|
||||
The default behavior of updatenode will be to attempt to perform all three
|
||||
types of updates. If you wish to limit updatenode to one or two specific
|
||||
actions you can use combinations of the "-S", "-P", and "-F" flags.
|
||||
|
||||
=head1 RETURN VALUE
|
||||
For example, If you just want to synchronize configuration file you could
|
||||
specify the "-F" flag. If you want to synchronize files and update
|
||||
software you would specify the "-F" and "-S" flags. See the descriptions
|
||||
of these flags and examples below.
|
||||
|
||||
Note: In a large cluster environment the updating of nodes in an ad hoc
|
||||
manner can quickly get out of hand, leaving the system administrator with
|
||||
a very confusing environment to deal with. The updatenode command is
|
||||
designed to encourage users to handle cluster updates in a manner that
|
||||
is recorded and easily repeatable. If you are not concerned about the
|
||||
structure the updatenode command provides you can use other xCAT support
|
||||
such as xdsh and xdcp to accomplish these update tasks.
|
||||
|
||||
=head2 B<To distribute and synchronize files>
|
||||
|
||||
The basic process for distributing and synchronizing nodes is:
|
||||
- Create a synclist file.
|
||||
- Indicate the location of the synclist file.
|
||||
- Run the updatenode command to update the nodes.
|
||||
|
||||
Files may be distributed and synchronized for both diskless and
|
||||
diskfull nodes. However, since some filesystems are mounted
|
||||
read-only on AIX diskless nodes it my not be possible to update all
|
||||
files on AIX systems. For example, any files under /usr on AIX
|
||||
diskless nodes cannot be updated.
|
||||
|
||||
More details for synchronization file is described "Sync-File HowTo".
|
||||
|
||||
Create the synclist file.
|
||||
|
||||
The synclist file contains the configuration entries that specify
|
||||
where the files should be synced to. In the synclist file, each
|
||||
line is an entry which describes the location of the source files
|
||||
and the destination location for the files on the target node.
|
||||
|
||||
The basic entry format looks like following:
|
||||
path_of_src_file1 -> path_of_dst_file1
|
||||
path_of_src_file1 path_of_src_file2 ... ->
|
||||
path_of_dst_directory
|
||||
|
||||
The path_of_src_file* should be the full path of the source file
|
||||
on the Management Node.
|
||||
The path_of_dst_file* should be the full path of the destination
|
||||
file on target node.
|
||||
The path_of_dst_directory should be the full path of the destina-
|
||||
tion directory.
|
||||
Since the synclist file is for common purpose, the target node
|
||||
need not be configured in it, it will be the noderange input to
|
||||
updatenode.
|
||||
|
||||
The following formats are supported:
|
||||
1) sync file /etc/file1 to the directory /etc on the node with
|
||||
the same file name
|
||||
/etc/file1 -> /etc
|
||||
2) sync file /etc/file2 to the file /etc/file2 on the node (with
|
||||
same file name)
|
||||
/etc/file2 -> /etc/file2
|
||||
3) sync file /etc/file2 to the file /etc/file3 on the node (with
|
||||
different file name)
|
||||
/etc/file2 -> /etc/file3
|
||||
4) sync the multiple files /etc/file1, /etc/file2, /etc/file3,
|
||||
... to the directory /tmp/etc (/tmp/etc must be a directory when
|
||||
multiple files are sync'd at one time). If the diretory does
|
||||
not exist, xdcp will create it.
|
||||
/etc/file1 /etc/file2 /etc/file3 -> /tmp/etc
|
||||
|
||||
Comment lines are NOT supported in the synlist file.
|
||||
|
||||
|
||||
Indicate the location of the synclist file.
|
||||
|
||||
For Linux nodes.
|
||||
|
||||
The path of the synclist should be following format:
|
||||
/install/custom/<inst_type>/<distro>/<profile>.<os>.<arch>.
|
||||
synclist
|
||||
<inst_type>: "install", "netboot"
|
||||
<distro>: "rh", "centos", "fedora", "sles"
|
||||
<profile>,<os> and <arch> are what you set for the node
|
||||
|
||||
|
||||
For AIX nodes.
|
||||
|
||||
Add a full path of the synclist file to the "synclists"
|
||||
attribute base on the xCAT osimage name used by the node
|
||||
in the osimage table.
|
||||
|
||||
chdef -t osimage -o myosimage synclists=/mydir/syncfile1
|
||||
|
||||
Run updatenode to synchronize the files.
|
||||
|
||||
updatenode <noderange> -F
|
||||
|
||||
|
||||
=head2 B<To install or update software (only available on Linux Nodes)>
|
||||
|
||||
The basic process for updating software on diskfull nodes is:
|
||||
- Copy the software to a mountable directory.
|
||||
- Create a record of what software to install.
|
||||
- Run the updatenode command to update the nodes.
|
||||
|
||||
On Linux systems
|
||||
|
||||
To install additional software for Linux diskfull nodes,
|
||||
|
||||
First, copy the extra rpms you are going to add on to
|
||||
/install/post/otherpkgs/<os>/<arch>/* directory where <os> and
|
||||
<arch> are defined in the <nodetype> table.
|
||||
|
||||
Second, add rpm names (without version number) into
|
||||
|
||||
/install/custom/install/<ostype>/profile.otherpkgs.pkglist
|
||||
|
||||
where <profile> is defined in the <nodetype> table. <ostype>
|
||||
is the operating system name without the version number.
|
||||
The following os types are recognized by xCAT.
|
||||
|
||||
centos
|
||||
fedora
|
||||
rh
|
||||
sles
|
||||
windows
|
||||
|
||||
Third, type:
|
||||
|
||||
updatenode <noderange> -S
|
||||
|
||||
|
||||
=head2 B<To re-run postscripts>
|
||||
|
||||
The scripts must be copied to the /install/postscripts
|
||||
directory on the xCAT management node. (Make sure they are
|
||||
executable.)
|
||||
|
||||
To run scripts on a node you must either specify them on the
|
||||
command line or you must add them to the "postscripts" attribute
|
||||
for the node.
|
||||
|
||||
To set the postscripts attribute of the node (or group)
|
||||
definition you can use the xCAT chdef command. Set the value to
|
||||
be a comma separated list of the scripts that you want to be
|
||||
executed on the nodes. The order of the scripts in the list
|
||||
determines the order in which they will be run. You could also set
|
||||
the postscripts value by directly editing the xCAT "postscripts"
|
||||
database table using the xCAT tabedit command.
|
||||
|
||||
Scripts may be run on both diskless and diskfull nodes.
|
||||
|
||||
To re-run all the customization scripts that have been designated
|
||||
for the nodes, (in the "postscripts" attribute), type:
|
||||
updatenode <noderange> -P
|
||||
|
||||
To re-run the "syslog" script for the nodes, type:
|
||||
updatenode <noderange> -P syslog
|
||||
|
||||
To re-run a list of scripts, type:
|
||||
updatenode <noderange> -P script1,script2
|
||||
|
||||
The flag '-P' is omitted when only postscripts parameters are
|
||||
specified.
|
||||
|
||||
Note: script1,script2 may or may not be designated as a scripts to
|
||||
automatically run on the node. However, if you want script1 and
|
||||
script2 get invoked next time the nodes are deployed then make sure
|
||||
to add them to the "postscripts" values for the nodes.
|
||||
|
||||
|
||||
=head1 B<PARAMETERS>
|
||||
|
||||
<noderange> A set of comma delimited xCAT node names
|
||||
and/or group names. See the xCAT "noderange"
|
||||
man page for details on additional supported
|
||||
formats.
|
||||
|
||||
<script1,script2...> A comma-separated list of script names.
|
||||
The scripts must be executable and copied
|
||||
to the /install/postscripts directory.
|
||||
|
||||
=head1 B<OPTIONS>
|
||||
|
||||

1. To install additional software for Linux stateful nodes, first copy the extra rpms you are going to add on to
|
||||
=head1 B<EXAMPLES>
|
||||
|
||||
/install/post/otherpkgs/<os>/<arch>/*
|
||||
1) To perform all updatenode features for the Linux nodes in the group
|
||||
"compute".
|
||||
updatenode compute
|
||||
|
||||
directory where <os> and <arch> are defined in the I<nodetype> table.
|
||||
The command will: run any scripts listed in the nodes "postscripts"
|
||||
attribute, install or update any software indicated in the
|
||||
/install/custom/install/<ostype>/profile.otherpkgs.pkglist (refer to the
|
||||
B<To install or update software part>), synchronize any files indicated by
|
||||
the synclist files specified in the osimage "synclists" attribute.
|
||||
|
||||
Second, add rpm names (without version number) into
|
||||
2) To perform a software update and file synchronization only on the node
|
||||
"clstrn01".
|
||||
updatenode clstrn01 -F -P
|
||||
|
||||
/install/custom/install/<ostype>/profile.otherpkgs.pkglist
|
||||
3) To re-run the postscripts which indicated in the postscripts attribute on
|
||||
the node "clstrn01".
|
||||
updatenode clstrn01 -P
|
||||
|
||||
where <profile> is defined in the I<nodetype> table. <ostype> is the operating system name without the version number. The following os types are recognized by xCAT.
|
||||
4) To re-run the postscripts script1 and script2 on the node "clstrn01".
|
||||
Copy these scripts to the /install/postscripts first.
|
||||
updatenode clstrn01 -P script1,script2
|
||||
Since flag '-P' is omitted when only postscripts parameters are specified,
|
||||
the following command line are equivalent.

5) To synchronize the files on the node "clstrn01". Prepare the synclist file.
|
||||
For AIX node, set the full path of synclist in the osimage table synclists
|
||||
attribute. For Linux node, put the synclist file into the location:
|
||||
/install/custom/<inst_type>/<distro>/<profile>.<os>.<arch>.synclist
|
||||
updatenode clstrn01 -F
