Measures reported by PANChasSwitchTest
Each PAN domain of the Egenera PAN Manager consists of several chassis that mounts different types of switches within them. Using this test, the administrators can figure out the current operating status of the chassis and identify the type of the switches present in each chassis. Apart from this, the number of uplink and downlink ports in each switch can be determined so that the administrator can easily identify whether there are any uplink/downlink ports available for pServer connectivity.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Status |
Indicates the current operating status of this chassis in this PAN Domain. |
|
This measure reports a value On if this chassis is currently powered on and a value Off if this chassis is powered off.
The numeric values that correspond to the above-mentioned measure values are as follows:
| Measure Value |
Numeric Value |
| Off |
0 |
| On |
1 |
Note: By default, this measure reports the above-mentioned Measure Values while indicating the current operating status of this chassis in this PAN Domain. However, the graph of this measure will be represented using the corresponding numeric equivalents of the i.e., 0 or 1. |
| Type |
Indicates the type of this switch available in this chassis. |
|
This measure reports the type of this switch as follows:
- Ethernet
- Fibre Channel(FC)
and
- Converged
The numeric values that correspond to the above-mentioned types are as follows:
| Type |
Numeric Value |
Description |
| Ethernet |
1 |
the switch supports only Ethernet ports and external connectivity to Ethernet networks. |
| Fibre Channel(FC) |
2 |
the switch supports only Fibre Channel ports and external connectivity to Fibre Channel storage arrays. |
| Converged |
3 |
the switch supports both Ethernet and Fibre Channel ports, and therefore external connectivity to Ethernet networks and Fibre Channel storage arrays |
Note: By default, this measure reports the above-mentioned Types while indicating the type of this switch in this chassis. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 1 to 3. |
| Num_uplink_ports |
Indicates the number of uplink ports in this switch of this chassis. |
Number |
An uplink is a collection of one or more ports bound together into a single entity that connects to external switches for either Ethernet (network) or Fibre Channel (storage) connectivity. Uplinks provide pServer network redundancy.
- Uplinks are defined as either Fibre Channel (for storage connectivity) or Ethernet (for network connectivity).
- All of the ports in a uplink must be the same type (Fibre Channel or Ethernet)
- A port may be included in only one uplink.
- Ports are combined into uplinks to provide connectivity for network or storage traffic from the pServers to the data center network or storage array.
- Ports can be added or removed from the uplink after creation, as long as the ports are of the same type (Fibre Channel or Ethernet). If you change ports on the uplink, you must first shutdown the pServers using that uplink for network traffic. When you reboot the pServers, they will resume network traffic on the newly modified uplink.
The detailed diagnosis capability of this measure if enabled, provides a detailed information of each port such as the PORT NO, the FABRIC NAME, UPLINK NAME, STATUS, TYPE and the USAGE i.e., the availability of this port for further use. |
| Num_downlink_ports |
Indicates the number of downlink ports in this switch of this chassis. |
