Measures reported by PANLpanInfoTest

A Logical Processing Area Network (LPAN) is a collection of PAN resources — pNodes, virtual storage and network resources — that are allocated as a group. You use PAN Manager software to configure these resources into one or more pServers. Typically, an LPAN represents the computing resources that are devoted to a single purpose or organization.

This test auto-discovers the LPAN in the Egenera PAN Manager and reports the current status of this LPAN. This test helps the administrators to analyze the following:

  • the average CPU Utilization of this LPAN;
  • how many pServers and pNodes are available in this LPAN and how many pServers are currently booting, shutting down etc.,?
  • What are the global pools and the local pools that are linked to the LPAN? and
  • HOw many network resources like MAC address, WWNs and physical resources like vSwitch are attached to this LPAN?

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Status Indicates the current status of this LPAN in the PAN Manager.   This measure reports a value Yes if this LPAN is active in the PAN MAnager and a value No if this LPAN is not active.

The numeric values that correspond to the above-mentioned measure values are as follows:

Measure Value Numeric Value
Yes 1
No 0

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the status of this LPAN. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 0 or 1.

Ave_cpu Indicates the average percentage of CPU that is currently utilized by this LPAN. Percent A low value is desired for this measure. A high value of this measure may indicate a performance bottleneck.
Total_pserver Indicates the number of pServers available in this LPAN. Number A pServer is a combination of a single pNode, an optional failover pNode, storage and network connections, that provides the capabilities of a conventional server.

The detailed diagnosis of this measure lists out all the pServers available in this LPAN.

Booting_pserver Indicates the number of pServers that are currently booting in this LPAN. Number  
Booted_pserver Indicates the number of pServers that were already booted in this LPAN. Number  
Shutting_pserver Indicates the number of pServers that are currently shutting down in this LPAN. Number  
Shutdown_pserver Indicates the number of pServers that were already shut down in this LPAN. Number  
Failing_pserver Indicates the number of pServers that are currently failing in this LPAN. Number  
Num_pnodes Indicates the number of pNodes that are currently available in this LPAN. Number A pNode is nothing but a physical blade server that provides the CPU processing and memory capabilities for a pServer.

The detailed diagnosis of this measure lists out the name of the pNodes available in this LPAN.
Num_linked_gpool Indicates the number of global pools that are currently attached to this LPAN. Number A global pool is a pNode Pool that is used by the whole PAN, from which pNodes are made available to pServers running in the PAN. A global pool spans LPANs i.e., the pNodes in a global pool can be made available to pServers running in any LPAN.

The detailed diagnosis of this measure lists out the names of the global pools in this LPAN, the available number of pNodes in each global pool, if the pServer is capable of booting from this global pool and the name of the local pool that is linked to this global pool.

Num_local_pool Indicates the number of local pools that are currently attached to this LPAN. Number A local pool is a set of processing resources used by a specific LPAN and from which pNodes can be assigned to pServers running in that LPAN.

The pNode in a local pool cannot be assigned to pServers running in other LPANs. Administrators can link a local pool to a Global Pool, so the PAN Manager will attempt to allocate a pNode from the global pool if it cannot obtain one from the local pool.

The detailed diagnosis of this measure lists out the names of the local pool, the number of pNodes that are currently available in each local pool and the name of the global pool that this local pool is linked to.

Num_vSwitch Indicates the number of vSwitches that are currently attached to this LPAN. Number The detailed diagnosis capability of this measure if enabled, lists out the names of the vSwitches and the type of each vSwitch.
Num_media_image Indicates the number of media images that are currently attached to this LPAN. Number Media images can be used for a variety of purposes such as installing pServer PAN Tools, installing pServer operating systems, and providing software to the pServers in an LPAN.
Num_wwns Indicates the number of WWNs (WORLD WIDE NAMEs) that are curently assigned to this LPAN. Number THE WORLD WIDE NAME (WWN) is a hardware address that uniquely identifies a target in a Storage Area Network (SAN). In PAN Manager, you assign WWNs to LPANs after which you use a vHBA to assign WWNs to a pServer.
Num_mac_add Indicates the number of MAC (MEDIA ACCESS CONTROL) addresses that are curently assigned to this LPAN. Number The Media Access Control (MAC) Address is a hardware address that uniquely identifies a component in an Ethernet network. In PAN Manager, each pServer vNIC has a unique MAC address.
