#
#  Sample stanza file used as input to the rollupdate command
#  This sample assumes that you have a simple set of updates that can
#  be applied to all nodes in any order.  Only the list of all nodes needs
#  to be specified.  You do not need to specify individual update groups.
#
#  For more complex updates, see the sample file rollupdate.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



# updateall:  Allows you to apply updates to all nodes without specifying
#    specific update groups.  This should be used for simple compute node
#    updates that have no special dependencies on other nodes and update order
#    is not important. Only those nodes that are currently active in
#    in the scheduler will be updated.
# For LoadLeveler reservation jobs, you can control which nodes will be
#    updated by specifying different machine requirements, classes, or other
#    controls that LL allows you in the LL job template that you provide.
# If updateall is used, the following entries MUST be specified in this file:
#       updateall_nodes  
#       updateall_nodecount
#       job_template
#       job_dir
# If updateall is used, the following entries can also be used:
#       maxupdates
#       oldfeature
#       newfeature
#       reservationduration
#       update_if_down
#       prescript (but NO prescriptnodes)
#       shutdowntimeout
#       outofbandcmd (but NO outofbandnodes)
#       bringupstatus,bringupappstatus
#       bringuptimeout
# All other entries in this file will be ignored
updateall=yes


# updateall_nodes:  The xCAT noderange of the nodes to be updated.
updateall_nodes=compute


# updateall_nodecount:  The number of nodes that will be reserved at one time
#    in the scheduler and updated together.  The smaller the number, the more
#    scheduler reservation jobs that will be submitted.
# NOTE:  LoadLeveler performance decreases with large numbers of 
#        reservations.  Do not set this value so low that you will exceed
#        the maximum number of reservations allowed for your cluster or
#        that you will degrade LL performance for your production jobs.
updateall_nodecount=3



# 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



# 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=all
maxupdates=16



#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/llall.tmpl


 
#jobdir:  Directory to write the job command 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.
# NOTE:  For updateall operation, update_if_down must be "no" or "cancel".
#        If set to "yes", "cancel" will be assumed.
#update_if_down=yes
update_if_down=no
#update_if_down=cancel




# prescript
#    (optional) Command to be run on the xCAT management node before issuing
#    the shutdown command for the nodes in the updategroup.
# NOTE:  For updateall operation, prescriptnodes are not supported.  
#        Prescripts will be run for all nodes.
#    You may specify the string $NODELIST if you would like the
#    comma-delimited list of xCAT nodenames passed into your command.
#    Multiple prescript entries can be specified. Each command will be run in 
#    order. 
#prescript=/u/admin/bin/shutdownGPFS $NODELIST



# 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



# 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
#   (optional) Out-of-band command to run on the xCAT management
#    node once the node has been shutdown but before it is rebooted.
# NOTE:  For updateall operation, outofbandnodes are not supported.  
#        Out-of-band commands will be run for all nodes.
#    You may specify the string $NODELIST if you would like the
#    comma-delimited list of xCAT nodenames passed into your command.
# Multiple outofbandcmd (with optional outofbandnodes) entries can be 
#    specified. Each command will be run in order. 
#outofbandcmd=/u/admin/bin/myfirmwareupdates $NODELIST



# 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
