perl
site - a table in the xCAT database.
site Attributes: key, value, comments, disable
Global settings for the whole cluster. This table is different from the other tables in that each attribute is just named in the key column, rather than having a separate column for each attribute. The following is a list of attributes currently used by xCAT organized into categories.
key
Attribute Name: Description
------------
- AIX ATTRIBUTES
- ------------nimprime : The name of NIM server, if not set default is the AIX MN.
If Linux MN, then must be set for support of mixed cluster (TBD).
useSSHonAIX: (yes/1 or no/0). Default is yes. The support for rsh/rcp is deprecated. useNFSv4onAIX: (yes/1 or no/0). If yes, NFSv4 will be used with NIM. If no, NFSv3 will be used with NIM. Default is no.
- DATABASE ATTRIBUTES
- -----------------auditnosyslog: If set to 1, then commands will only be written to the auditlog table.
If this attribute is set to 1 and auditskipcmds=ALL means no logging of commands. Default is to write to both the auditlog table and syslog.
- auditskipcmds: List of commands and/or client types that will not be
written to the auditlog table and syslog. See auditnosyslog. 'ALL' means all cmds will be skipped. If attribute is null, all commands will be written. clienttype:web would skip all commands from the web client For example: tabdump,nodels,clienttype:web will not log tabdump, nodels or any web client commands.
- databaseloc: Directory where we create the db instance directory.
Default is /var/lib. Only DB2 is currently supported. Do not use the directory in the site.installloc or installdir attribute. This attribute must not be changed once db2sqlsetup script has been run and DB2 has been setup.
- excludenodes: A set of comma separated nodes and/or groups that would automatically
be subtracted from any noderange, it can be used for excluding some failed nodes for any xCAT commands. See the 'noderange' manpage for details on supported formats.
- nodestatus: If set to 'n', the nodelist.status column will not be updated during
the node deployment, node discovery and power operations. The default is to update.
skiptables: Comma separated list of tables to be skipped by dumpxCATdb
- skipvalidatelog: If set to 1, then getcredentials and getpostscripts calls will not
be logged in syslog.
- DHCP ATTRIBUTES
- -------------dhcpinterfaces: The network interfaces DHCP should listen on. If it is the same for all
nodes, use a comma-separated list of the NICs. To specify different NICs for different nodes, use the format: "xcatmnbond0", where xcatmn is the name of the management node, DHCP should listen on the eth1 and eth2 interfaces. All the nodes in group 'service' should listen on the 'bond0' interface.
To disable the genesis kernel from being sent to specific interfaces, a ':noboot' option can be appended to the interface name. For example, if the management node has two interfaces, eth1 and eth2, disable genesis from being sent to eth1 using: "eth1:noboot,eth2".
dhcpsetup: If set to 'n', it will skip the dhcp setup process in the nodeset cmd.
dhcplease: The lease time for the dhcp client. The default value is 43200.
- disjointdhcps: If set to '1', the .leases file on a service node only contains
the nodes it manages. And when 'sharedtftp' is disabled, nodeset handles boot loader configuration on a service node only for the nodes it manages. The default value is '0'. It means include all the nodes in the subnet.
- pruneservices: Whether to enable service pruning when noderm is run (i.e.
removing DHCP entries when noderm is executed)
- managedaddressmode: The mode of networking configuration during node provision.
If set to 'static', the network configuration will be configured in static mode based on the node and network definition on MN. If set to 'dhcp', the network will be configured with dhcp protocol. The default is 'dhcp'.
- DNS ATTRIBUTES
------------dnshandler: Name of plugin that handles DNS setup for makedns.
domain: The DNS domain name used for the cluster.
- forwarders: The DNS servers at your site that can provide names outside of the cluster.
The makedns command will configure the DNS on the management node to forward requests it does not know to these servers. Note that the DNS servers on the service nodes will ignore this value and always be configured to forward to the management node.
- dnsforwardmode: (first or only or no). This is to set forward value in named.conf options section.
"first": causes DNS requests to be forwarded before an attempt is made to resolve them via the root name servers. "only": all requests are forwarded and none sent to the root name servers. "no": no request will be forwarded. This is the default value if not specified.
emptyzonesenable: (yes or no). This is to set empty-zones-enable value in named.conf options section.
master: The hostname of the xCAT management node, as known by the nodes.
- nameservers: A comma delimited list of DNS servers that each node in the cluster should
use. This value will end up in the nameserver settings of the /etc/resolv.conf on each node. It is common (but not required) to set this attribute value to the IP addr of the xCAT management node, if you have set up the DNS on the management node by running makedns. In a hierarchical cluster, you can also set this attribute to "<xcatmaster>" to mean the DNS server for each node should be the node that is managing it (either its service node or the management node).
- externaldns: To specify that external dns is used. If externaldns is set to any value
then, makedns command will not start the local nameserver on xCAT MN. Default is to start the local nameserver.
- dnsupdaters: The value are ',' separated string which will be added to the zone config
section. This is an interface for user to add configuration entries to the zone sections in named.conf.
- dnsinterfaces: The network interfaces DNS should listen on. If it is the same for all
nodes, use a simple comma-separated list of NICs. To specify different NICs for different nodes, use the format: "xcatmnbond0", where xcatmn is the name of the management node, and DNS should listen on the eth1 and eth2 interfaces. All the nods in group 'service' should listen on the 'bond0' interface.
NOTE: If using this attribute to block certain interfaces, make sure the IP maps to your hostname of xCAT MN is not blocked since xCAT needs to use this IP to communicate with the local NDS server on MN.
- namedincludes: A comma-separated list of file paths that will be included in
named.conf, using named 'include' statement. This can allow users to include local configuration options that will not be overwritten by 'makedns -n'
- HARDWARE CONTROL ATTRIBUTES
-------------------------blademaxp: The maximum number of concurrent processes for blade hardware control.
- ea_primary_hmc: The hostname of the HMC that the Integrated Switch Network
Management Event Analysis should send hardware serviceable events to for processing and potentially sending to IBM.
- ea_backup_hmc: The hostname of the HMC that the Integrated Switch Network
Management Event Analysis should send hardware serviceable events to if the primary HMC is down.
- enableASMI: (yes/1 or no/0). If yes, ASMI method will be used after fsp-api. If no,
when fsp-api is used, ASMI method will not be used. Default is no.
fsptimeout: The timeout, in milliseconds, to use when communicating with FSPs.
- hwctrldispatch: Whether or not to send hw control operations to the service
node of the target nodes. Default is 'y'.(At present, this attribute is only used for IBM Flex System)
- ipmidispatch: Whether or not to send ipmi hw control operations to the service
node of the target compute nodes. Default is 'y'.
- ipmimaxp: The max # of processes for ipmi hw ctrl. The default is 64. Currently,
this is only used for HP hw control.
ipmiretries: The # of retries to use when communicating with BMCs. Default is 3.
- ipmisdrcache: If set to 'no', then the xCAT IPMI support will not cache locally
the target node's SDR cache to improve performance.
- ipmitimeout: The timeout to use when communicating with BMCs. Default is 2.
This attribute is currently not used.
- maxssh: The max # of SSH connections at any one time to the hw ctrl point for PPC
This parameter doesn't take effect on the rpower command. It takes effects on other PPC hardware control command getmacs/rnetboot/rbootseq and so on. Default is 8.
- syspowerinterval: For SystemP CECs, this is the number of seconds the rpower command
will wait between performing the action for each CEC. For SystemX IPMI servers, this is the number of seconds the rpower command will wait between powering on <syspowermaxnodes> nodes at a time. This value is used to control the power on speed in large clusters. Default is 0.
- syspowermaxnodes: The number of servers to power on at one time before waiting
'syspowerinterval' seconds to continue on to the next set of nodes. If the noderange given to rpower includes nodes served by different service nodes, it will try to spread each set of nodes across the service nodes evenly. Currently only used for IPMI servers and must be set if 'syspowerinterval' is set.
- powerinterval: The number of seconds the rpower command to LPARs will wait between
performing the action for each LPAR. LPARs of different HCPs (HMCs or FSPs) are done in parallel. This is used to limit the cluster boot up speed in large clusters. Default is 0. This is currently only used for system p hardware.
- ppcmaxp: The max # of processes for PPC hw ctrl. If there are more than ppcmaxp
hcps, this parameter will take effect. It will control the max number of processes for PPC hardware control commands. Default is 64.
- ppcretry: The max # of PPC hw connection attempts to HMC before failing.
It only takes effect on the hardware control commands through HMC. Default is 3.
- ppctimeout: The timeout, in milliseconds, to use when communicating with PPC hw
through HMC. It only takes effect on the hardware control commands through HMC. Default is 0.

directory on the diskfull nodes after the postscripts are run with no errors. Default is no.
- db2installloc: The location which the service nodes should mount for
the db2 code to install. Format is hostname:/path. If hostname is omitted, it defaults to the management node. Default is /mntdb2.
defserialflow: The default serial flow - currently only used by the mknb command.
defserialport: The default serial port - currently only used by mknb.
defserialspeed: The default serial speed - currently only used by mknb.

prefix (e.g. 00:11:aa)
- genpasswords: Automatically generate random passwords for BMCs when configuring
them.
installdir: The local directory name used to hold the node deployment packages(obsoleted).
- installloc: The location from which the service nodes should mount the
deployment packages in the format hostname:/path. If hostname is omitted, it defaults to the management node. The path must match the path in the installdir attribute.
iscsidir: The path to put the iscsi disks in on the mgmt node.
- mnroutenames: The name of the routes to be setup on the management node.
It is a comma separated list of route names that are defined in the routes table.
- runbootscripts: If set to 'yes' the scripts listed in the postbootscripts
attribute in the osimage and postscripts tables will be run during each reboot of stateful (diskful) nodes. This attribute has no effect on stateless and statelite nodes. Run the following command after you change the value of this attribute: 'updatenode <nodes> -P setuppostbootscripts'
- precreatemypostscripts: (yes/1 or no/0). Default is no. If yes, it will
instruct xCAT at nodeset and updatenode time to query the db once for all of the nodes passed into the cmd and create the mypostscript file for each node, and put them in a directory of tftpdir(such as: /tftpboot) If no, it will not generate the mypostscript file in the tftpdir.
- secureroot: If set to 1, xCAT will use secure mode to transfer root password hash
during the installation. Default is 0.
setinstallnic: Set the network configuration for installnic to be static.
- sharedtftp: Set to 0 or no, xCAT should not assume the directory
in tftpdir is mounted on all on Service Nodes. Default is 1/yes. If value is set to a hostname, the directory in tftpdir will be mounted from that hostname on the SN
- sharedinstall: Indicates if a shared file system will be used for installation
resources. Possible values are: 'no', 'sns', or 'all'. 'no' means a shared file system is not being used. 'sns' means a shared filesystem is being used across all service nodes. 'all' means that the management as well as the service nodes are all using a common shared filesystem. The default is 'no'.
xcatconfdir: Where xCAT config data is (default /etc/xcat).
- xcatdebugmode: the xCAT debug level. xCAT provides a batch of techniques
to help user debug problems while using xCAT, especially on OS provision, such as collecting logs of the whole installation process and accessing the installing system via ssh, etc. These techniques will be enabled according to different xCAT debug levels specified by 'xcatdebugmode', currently supported values: '0': disable debug mode '1': enable basic debug mode '2': enable expert debug mode For the details on 'basic debug mode' and 'expert debug mode', refer to xCAT documentation.
- REMOTESHELL ATTRIBUTES
--------------------nodesyncfiledir: The directory on the node, where xdcp will rsync the files
- SNsyncfiledir: The directory on the Service Node, where xdcp will rsync the files
from the MN that will eventually be rsync'd to the compute nodes.
- sshbetweennodes: Comma separated list of groups of compute nodes to enable passwordless
root ssh to the nodes during install or running 'xdsh -K'. The default is ALLGROUPS. Set to NOGROUPS to disable.
Service Nodes are not affected by this attribute as they are always configured with passwordless root access. If using the zone table, this attribute in not used.
- SERVICES ATTRIBUTES
- -----------------consoleondemand: When set to 'yes', conserver connects and creates the console
output only when the user opens the console. Default is 'no' on Linux, 'yes' on AIX.
- httpport: The port number that the booting/installing nodes should contact the
http server on the MN/SN on. It is your responsibility to configure the http server to listen on that port - xCAT will not do that.
- nmapoptions: Additional options for the nmap command. nmap is used in pping,
nodestat, xdsh -v and updatenode commands. Sometimes additional performance tuning may be needed for nmap due to network traffic. For example, if the network response time is too slow, nmap may not give stable output. You can increase the timeout value by specifying '--min-rtt-timeout 1s'. xCAT will append the options defined here to the nmap command.
- ntpservers: A comma delimited list of NTP servers for the service node and
the compute node to sync with. The keyword <xcatmaster> means that the node's NTP server is the node that is managing it (either its service node or the management node).
- extntpservers: A comma delimited list of external NTP servers for the xCAT
management node to sync with. If it is empty, the NTP server will use the management node's own hardware clock to calculate the system date and time
- svloglocal: If set to 1, syslog on the service node will not get forwarded to the
management node.
timezone: (e.g. America/New_York)
tftpdir: The tftp directory path. Default is /tftpboot
- tftpflags: The flags that used to start tftpd. Default is '-v -l -s /tftpboot
-m /etc/tftpmapfile4xcat.conf' if tftplfags is not set
- useNmapfromMN: When set to yes, nodestat command should obtain the node status
using nmap (if available) from the management node instead of the service node. This will improve the performance in a flat network.
- vsftp: Default is 'n'. If set to 'y', xcatd on the management node will automatically
start vsftpd. (vsftpd must be installed by the admin). This setting does not apply to service nodes. For service nodes, set servicenode.ftpserver=1.
- FQDNfirst: Fully Qualified Domain Name first. If set to 1/yes/enable, the /etc/hosts
entries generated by 'makehosts' will put the FQDN before the PQDN(Partially Qualified Domain Name). Otherwise, the original behavior will be performed.
- hierarchicalattrs: A comma delimited list of table attributes(e.g. postscripts, postbootscripts)
that will be included hierarchically. Attribute values for all the node's groups will be applied to the node in the groups' order except the repeat one. By default, comma is used to combine the values. But some columns use different delimiter, to specify delimiter for those columns as format of 'column:delimiter'.
- dbtracelevel: The trace level for the database access log. To activate this setting, please.
restart xcatd or send HUP signal to the 'xcatd: DB Access' process, Like: . pkill -f -HUP 'xcatd: DB Access' Currrent support values: 0: disable the trace log for db 1: trace the calls of database subroutines 2: Besides the log from level 1, trace the event to build the cache for the table 3: Besides the log from level 2, trace the event with cache hit 4: Besides the log from level 3, trace the SQL statement for the db access With this configuration, xcat will send the log to syslog very frequently, some of the log may be lost if imjournal is enabled by rsyslog. Please see #3910 for the detail.
- VIRTUALIZATION ATTRIBUTES
- -----------------------usexhrm: Have xCAT execute the xHRM script when booting up KVM guests to configure
the virtual network bridge.
- vcenterautojoin: When set to no, the VMWare plugin will not attempt to auto remove
and add hypervisors while trying to perform operations. If users or tasks outside of xCAT perform the joining this assures xCAT will not interfere.
- vmwarereconfigonpower: When set to no, the VMWare plugin will make no effort to
push vm.cpus/vm.memory updates from xCAT to VMWare.
- persistkvmguests: Keep the kvm definition on the kvm hypervisor when you power off
the kvm guest node. This is useful for you to manually change the kvm xml definition file in virsh for debugging. Set anything means enable.
- XCAT DAEMON ATTRIBUTES
- --------------------tokenexpiredays: Number of days before REST API token will expire. The default is 1.
use 'never' if you want your token to never expire.
- useflowcontrol: (yes/1 or no/0). If yes, the postscript processing on each node
contacts xcatd on the MN/SN using a lightweight UDP packet to wait until xcatd is ready to handle the requests associated with postscripts. This prevents deploying nodes from flooding xcatd and locking out admin interactive use. This value works with the xcatmaxconnections and xcatmaxbatch attributes. Is not supported on AIX. If the value is no, nodes sleep for a random time before contacting xcatd, and retry. The default is no. See the following document for details: Hints_and_Tips_for_Large_Scale_Clusters
- xcatmaxconnections: Number of concurrent xCAT protocol requests before requests
begin queueing. This applies to both client command requests and node requests, e.g. to get postscripts. Default is 64.
- xcatmaxbatchconnections: Number of concurrent xCAT connections allowed from the nodes.
Value must be less than xcatmaxconnections. Default is 50.
xcatdport: The port used by the xcatd daemon for client/server communication.
xcatiport: The port used by xcatd to receive install status updates from nodes.
xcatlport: The port used by xcatd command log writer process to collect command output.
- xcatsslversion: This is the SSL_version option xcatd used and passed to
IO::Socket::SSL->start_SSL(). By default, this value is set to empty. In this case, xcatd will use SSLv23:!SSLv2:!SSLv3:!TLSv1 internally. For more detail, see https://metacpan.org/pod/IO::Socket::SSL
xcatsslciphers: The ssl cipher by xcatd. Default is 3DES.
