#
#
#  Sample stanza file used as input to the rollupdate command
#  This sample uses explicit update groups and allows mutual exclusion
#  in updates between nodes and other functions.
#
#  For an example of simple updates using the updateall feature instead of
#  update groups, see the sample file rollupdate_all.input.sample
#
#  Unless otherwise noted in the descriptions below, if multiple stanza
#  lines are specified for the same keyword, only the FIRST entry will be
#  used and all others will be ignored.
#
#



# scheduler:  The job scheduler used to submit the rolling update jobs
#    Currently only LoadLeveler is supported
scheduler=loadleveler


# scheduser:  The userid with authority to submit scheduler jobs
#             Note:  LL does not allow jobs to be submitted by root
scheduser=loadl



# Scheduler Feature values 
#    Node feature values that will be changed in the scheduler during the
#    update process.  These features can be used if users need to run jobs
#    on only old nodes or only new nodes, but cannot have the job span both
#    old and new nodes due to software incompatibilities.
# oldfeature:  This feature value will be removed from the node definition
#    in the scheduler after the node has been updated
oldfeature=oldvalue

# newfeature:  A new feature value that will be set in the scheduler for each
#    node after it has been updated.  
newfeature=newvalue



#
# updategroup:  A set of nodes to be updated as a single group
#        updategroup = name(noderange)
#    where "name" is the name to be assigned to the updategroup and 
#    "noderange" is any valid xCAT noderange syntax (see noderange man page)
#    You may list multiple updategroup stanzas in this file and all of them will
#    be processed.
updategroup=ns01(c4lpar201-c4lpar204)
updategroup=ns11(c4lpar211-c4lpar214)

# mapgroups:  Many updategroups can also be defined through a 
#    single statement using nodegroup mappings.    
#        mapgroups=nodegroup_range
#    Where nodegroup_range is processed in the same way xCAT handles node name
#    ranges to generate a set of nodegroup names.  Each nodegroup will be
#    mapped to an updategroup with the same name.
# You may list multiple mapgroups stanzas in this file and all of them will
#    be processed.
# For example, the following will create 10 updategroups from the 10
#    nodegroups named block01 to block10.
mapgroups=block[01-10]



# mutex:  Identify updategroups that are mutually exclusive and must not be 
#    updated at the same time in order to maintain active resources within
#    the cluster. Only 1 updategroup listed in the entry will be updated at 
#    a time.
#        mutex=updategroup,updategroup,...
#    For example, the update jobs for ns1 and for ns2 will not be allowed 
#    to run at the same time:
mutex=ns1,ns2

# You may list multiple mutex stanzas in this file to identify different
#    sets of mutual exclusion.  
# Multiple mutually exclusive sets can be specified using updategroup name 
#    ranges. For example, the following:
#mutex=block[1-3]a,block[1-3]b,block[1-3]c
# would be equivalent to:
#mutex=block1a,block1b,block1c
#mutex=block2a,block2b,block2c
#mutex=block3a,block3b,block3c



# maxupdates:  Maximum number of updategroups that can be updated at one time 
#    This allows you to ensure you will always have enough computing
#    resources in your cluster and that not all nodes will attempt to
#    be updated at once.
#    A value of "all" specifies that there is no restriction
# maxupdates=16
maxupdates=all



# jobtemplate:  Scheduler job template file.  See this sample LoadLeveler file 
#     for details on how the template will be processed:
jobtemplate=/opt/xcat/share/xcat/rollupdate/ll.tmpl



#jobdir:  Directory to write the job command files and other data files to.
#    For LL, this directory needs to be on a filesystem available to all nodes.
jobdir=/u/loadl/rollupdate_jobs



#reservationcallback:  INTERNAL KEYWORD used for development only.
#    This is the reservation notify or callback command.  
#    For Loadleveler, this script must reside on the LoadLeveler central
#    manager and will be called when the reservation for an updategroup
#    becomes active.
#    The default is:
#reservationcallback=/opt/xcat/bin/runrollupdate
#


#reservationduration:  Maximum time to hold a LoadLeveler reservation for 
#    the update process.  This value in minutes should be longer than the 
#    expected time to shutdown, update, and reboot all the nodes in an update 
#    group.  xCAT will release the nodes from the reservation as they come 
#    back up, and will cancel the reservation when the last node has completed.
reservationduration=15



#update_if_down:  If set to "yes", also attempt the update for any node in an 
#    updategroup that is down or not active/available in the scheduler
#    (useful if you have nodes that are not part of your scheduler's cluster).
# If set to "no", any node in an updategroup that is not active in the 
#    scheduler will be skipped.
# If set to "cancel", if any node in an updategroup is not active,
#    the entire updategroup will be skipped.
update_if_down=yes
#update_if_down=no
#update_if_down=cancel



# prescript
# prescriptnodes
#     (optional) Command to be run on the xCAT management node before issuing
#     the shutdown command for the nodes in the updategroup.
# If prescriptnodes is also specified, the command will only be run for
#     nodes being from the updategroup that are also included in that xCAT
#     noderange.
# If prescriptnodes is not specified, the command will be run for all
#    nodes in the updategroup.
# For prescript, you may specify the string $NODELIST if you would like the
#    comma-delimited list of xCAT nodenames passed into your command.
#    This can be used to run operations such as shutting down the global
#    filesystem on all the nodes, or moving critical services
#    to a backup server for specific nodes.
# Multiple prescript entries or prescript/prescriptnodes pairs of entries may
#    be specified. Each command will be run in order. 
#
#prescript=/u/admin/bin/shutdownGPFS $NODELIST
#
#prescript=/u/admin/bin/moveGPFSconfigserver $NODELIST
#prescriptnodes=gpfsconfig
#
#prescript=/u/admin/bin/moveLLscheduler $NODELIST
#prescriptnodes=llsched
#
#prescript=/u/admin/bin/moveXCATservicenode $NODELIST
#prescriptnodes=service



# NOT IMPLEMENTED YET! FUTURE SUPPORT FOR ROLLING UPDATE OF DISKFULL NODES
# shutdownrequired:  Should a shutdown command be sent to the nodes.  
#    Shutdown is required for diskless nodes.  For diskfull nodes, simple 
#    updates may be applied to the nodes through prescripts, and a node 
#    reboot may not be required. 
# Default is "yes".
shutdownrequired=yes



# NOT IMPLEMENTED YET!  FUTURE SUPPORT...
# shutdownorder:  (optional) The order that nodes within an updategroup
#    will be shut down.  The value is any valid xCAT noderange.  
#    Multiple shutdownorder entries may be specified, and they will be 
#    processed as entered in this file.  If more than one node in the 
#    updategroup matches a shutdownorder entry, they will be shutdown at 
#    the same time.  xCAT will wait until the node is completely shutdown
#    before proceeding to the next nodes.  Any nodes in the updategroup not 
#    listed will be shutdown at the end.
#shutdownorder=compute
#shutdownorder=gpfsio
#shutdownorder=service



# shutdowntimeout:  (optional) The number of minutes xCAT should wait for
#    an OS shutdown to complete before giving up and issuing a hard power off
#    command and continuing with the rolling update process.
shutdowntimeout=5



# outofbandcmd
# outofbandnodes
#    (optional) Out-of-band command to run on the xCAT management
#    node once the node has been shutdown but before it is rebooted.
# If outofbandnodes is also specified, the command will only be run for
#    nodes from the updategroup that are also included in that xCAT noderange.
# If outofbandnodes is not specified, the command will be run for all
#    nodes in the updategroup.
# You may specify the string $NODELIST if you would like the
#    comma-delimited list of xCAT nodenames passed into your command.
#    This can be used to run operations such as firmware updates.
# Multiple outofbandcmd entries or outofbandcmd/outofbandnodes pairs of
#    entries can be specified. Each command will be run in order. 
#
#outofbandcmd=/u/admin/bin/myfirmwareupdates $NODELIST
#
#outofbandcmd=/u/admin/bin/IOsubsystemupdates $NODELIST
#outofbandnodes=gpfsio



# bringuporder:  (optional) The order that nodes within an updategroup
#    will be brought up  The value is any valid xCAT noderange.  
# Multiple bringuporder entries may be specified, and they will be processed
#    as entered in this file.  If more than one node in the updategroup
#    matches a bringuporder entry, they will be brought up at the same time.
#    xCAT will wait until the node is completely shutdown before proceeding
#    to the next set of nodes.  Any nodes in the updategroup not listed will be
#    brought up at the end.
#bringuporder=service
#bringuporder=gpfsio
#bringuporder=compute



# bringupstatus:  
#  OR
# bringupappstatus:  
#    The xCAT database node status or appstatus value that xCAT will check and 
#    will wait for to determine that the node is up.  Once this status is
#    reached, xCAT will continue bringing up more nodes (if bringuporder is set)
#    and will release this node from the scheduler reservation.
# If both attributes are set, only bringupappstatus will be used.
#bringupappstatus="gpfs=ready"
bringupstatus=booted



# bringuptimeout:  (optional) The maximum number of minutes xCAT should wait
#    after issuing the rpower on command for the nodes to reach bringupstatus 
#    before giving up.  If using bringuporder and this timeout is reached for
#    one set of nodes, no additional nodes will be attempted to be brought up.  
#    The scheduler reservation will be cancelled. 
bringuptimeout=10
