opcnode - command to maintain nodes, node groups and template assignments

Note: HP renamed the product called now HP operations manager way too many times. Also it is very inconsistent with using abbreviations. Here we will assume that the term "HP Operations manager" and abbreviations HPOM, OMU, and OVO  mean the same thing :-)

Use the command opcnode to maintain nodes, node groups, template and category assignments. It enables assignment of modified or new policies to nodes or node groups. Can add new nodes (using standard parameters) and assign them to node groups. Additionally, users can check the configuration of a node or node group by listing the assigned templates or nodes, change the communication type of a list of nodes, change the machine type of a list of nodes, change the node type of a list of nodes.

 It is a quite convenient way to disable receiving messages from a number of nodes.

It can be used by a HPOM user with no administrative privileges (e.g. template administrator), who has root access to the Management Server.

For handling virtual nodes (aka resource group) you can promote physical nodes to virtual ones, re-physicalize them again, assign other physical nodes to a virtual one or even change/assign a cluster package name to the virtual node.

Use opcnode to assign and design categories to specified nodes. You can also list all assigned categories to specified nodes.

Usage

If opcnode is called without any option, the usage string appears.

opcnode uses two types of parameter: operations and attributes. The operations are indicated by a '-' like -<operation>. Attributes are always specified through an assignment like <attrib>=<value>. Each parameter must be specified in full.

Note: Only one operation is allowed per call, opcnode cannot perform more than one operation per call.

Operations

-add_node

Adds a node to the HPOM Node Bank in the HPOM database. Mandatory attributes are: node_name, net_type, mach_type and group_name. Optional attributes are: node_label, comm_type, node_type, ip_addr, node_hier and layout_group. The node group (specified with group_name) and layout group (layout_group) must already exist because the node will be assigned to it directly after it is added to the database. All other node attributes, which cannot be specified here, are taken from the node defaults in the database for the specified node type.

-del_node

Deletes the specified node from the Node Bank and the HPOM database. Mandatory attributes are: node_name and net_type. The node's assignments to node groups will be removed.

-chg_commtype

Changes the communication type of one or more nodes. To specify the nodes give a node name or list of node names. This makes it possible to add opcnode as an HPOM Application to the HPOM Application Bank using opcappl command line tool. For more information see the HP Operations Manager for UNIX: Administrator's Reference and man page for opcappl.
Mandatory attributes are: either node_name or node_list and comm_type. The node list must be enclosed in ' ' or " ".
If net_type is not specified, NETWORK_IP is used. But it is also possible to specify another network type with net_type.

-chg_machtype

Changes the machine type of one or more nodes with the network type IP. To specify the nodes give a node name or list of node names. This makes it possible to add opcnode as an HPOM Application to the HPOM Application Bank using opcappl command line tool. For more information see the HP Operations Manager for UNIX: Administrator's Reference and man page for opcappl.
Mandatory attributes are: either node_name or node_list and mach_type. The node list must be enclosed in ' ' or " ".
The network type of all specified nodes must be NETWORK_IP. It is not possible to specify another network type with net_type.

-chg_nodetype

Changes the node type of one or more nodes. To specify the nodes give a node name or list of node names. This makes it possible to add opcnode as an HPOM Application to the HPOM Application Bank using opcappl command line tool. For more information see the HP Operations Manager for UNIX: Administrator's Reference and man page for opcappl.
Mandatory attributes are: either node_name or node_list and node_type. The node list must be enclosed in ' ' or " ".
If net_type is not specified, NETWORK_IP is used. But it is also possible to specify another network type with net_type.

-list_nodes

Prints a list of all nodes in the HPOM database to stdout. The Name, Label, IP-Address, Network-Type, Machine-Type and the Communication-Type is printed for each node. The query can be restricted with the node_list and group_name attributes (if both are specified, all nodes meeting at least one of the criteria will be printed). Additionally you can restrict the results with the net_type, mach_type and comm_type attributes.

-add_group

Adds a node group to the HPOM Node Group Bank in the HPOM database. Mandatory attributes are: group_name. Optional parameters are: group_label.
It is then possible to assign nodes and templates to the node group.

MONITORED

MESSAGE_ALLOWED

node_list

node_list specifies the names of the nodes whose communication type, machine type or node type should be changed. The node names must be separated by blanks or separators, defined with sep, and enclosed in ' ' or " ". node_list is used for the operation chg_commtype, chg_machtype, chg_nodetype, assign_cat, deassign_cat and list_ass_cat.
If no network type is specified, NETWORK_IP is used for all nodes. But it is also possible to specify another network type with net_type that is then used for all nodes in the node list.

templ_name

templ_name specifies the name of a template or template group.

templ_type

templ_type specifies the type of a template. To specify a template or template group, the name and the template type must be given. Possible template types are:

TEMPLATE_GROUP

CONSOLE_TEMPLATE

OPCMSG_TEMPLATE

LOGFILE_TEMPLATE

MONITOR_TEMPLATE

SNMP_TEMPLATE

EC_TEMPLATE

SCHEDULE_TEMPLATE

id

id specifies the agent ID of the given node.

dynamic_ip

dynamic_ip specifies if the node address should be changeable by DHCP.

cluster_package

cluster_package specifies the name of the new HA resource group. This parameter can only be used with the operation set_virtual.

sep

sep specifies optional separator character for node_list. Default is blank.

ip_addr

ip_addr specifies the IP Address of the node in "dot" notation (for example: ip_addr=15.1.2.3). Specifying the IP address allows to use a specific IP address when adding a node with mutliple IP addresses.

cat_list

cat_list specifies optional separator character for node_list. Default is blank.

pol_name

pol_name specifies the name of the policy to be (de)assigned to a node. A policy is uniquely identified by its name, type and version.

pol_type

version

version specifies the version of the policy to be (de)assigned to a node. Version must be in <major>.<minor> form, where both <major> and <minor> are numbers between 1 and 9999 inclusively. A policy is uniquely identified by its name, type and version.

pol_group

pol_group specifies the name of the policy group to be (de)assigned to a node. Full path of the policy group must be specified e.g. /a/b/c.

mode

mode determines the way a policy is assigned to a node. The possible values of this attribute are:

FIX (default)

MINOR_TO_LATEST

LATEST

Option FIX assigns the specified policy version to the node. If option MINOR_TO_LATEST is used the highest minor version that has the specified major version is assigned to the node. If mode has value of LATEST, the absolute highest version of the policy is assigned to the node. In MINOR_TO_LATEST and LATEST cases, assignment changes automatically as new versions that satisfy the criteria are created. In case of MINOR_TO_LATEST, assignment will be updated if a new policy version which has the same major number as the originally assigned one is created. With LATEST, the assignment updates as soon as the new highest policy version is created.

This command can only be issued by the root user. To enable other users to execute this command, the system administrator must change the file's attributes and copy it to a location which is included in the $PATH variable.

[Dec 23, 2010] Checking all Templates

Oct 1, 2010 | IT Resource Center forums

Archana1

Hello experts,

We have 300 server as HPOM 8 agents. Now I have situation to verify templates deployed on all 300 agents. Please advice

Is there any simplest command or way ? other than checking manually on each agent.

Larry Klasmier :

use ovpolicy from the management node. If you have a list of the managed nodes you can script it to access all 300 nodes. if not you can use opcnode to feed the node names to the ovpolicy command. Check out the man pages for both ovpolicy and opcnode.

sekar sundaram:

get the nodes list on a file opcnode -list_nodes > /tmp/nodeslist

then run ovdeploy on each node thru a for loop:

for NODE in `cat /tmp/nodeslist` do ovdeploy -cmd "ovpolicy -list" -node $NODE done

better forward the output to a file, so that you can check it later..

ovdeploy -cmd "ovpolicy -list" -node $NODE >> /tmp/nodes-policies

NOTE - "ovpolicy" command works on OVO 8 agents and "opctemplate" command for OVO 7 agents.

Larry Klasmier:

No need to run ovdeploy. ovpolicy can query the policy on a managed node from the management server

ovpolicy -list -node <managed node>
