| Networking information produced by commands is also peculiar to the vPar on which you've issued the command. Networking configuration of vPars is covered in Chapter 13. Let's take a look at the network interface on two different vPars configured on the same server. First let's look at the output of vPar cable1 with a hostname of cvhdcon3: # hostname cvhdcon3 # netstat -I lan0 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll lan0 1500 172.16.15.0 cvhdcon3 12785 0 11855 0 3 # # netstat -in Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll lan0 1500 172.16.15.0 172.16.15.36 12990 0 12052 0 3 lo0 4136 127.0.0.0 127.0.0.1 7616 0 7616 0 0 # # lanscan Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI Path Address In# State NamePPA ID Type Support Mjr# 0/0/0/0 0x00306E06F6BA 0 UP lan0 snap0 1 ETHER Yes 119 # This output shows that lan0 is the network interface devoted to vPar cable1 on this server. The lanscan output shows that this interface has a hardware path of 0/0/0/0. This is on the Core I/O card that was configured as a component of the vPar when it was created with -a io:0/0. The LAN interface on the Core I/O card was not explicitly called out when cable1 was created because 0/0/0/0 is an implied component of the Core I/O card at 0/0. Let's now take a look at the second vPar running on this server, called cable2 with a hostname of cvhdcon4: # hostname cvhdcon4 # netstat -I lan1 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll lan1 1500 172.16.14.0 cvhdcon4 3463 0 1603 0 2 # # netstat -in Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll lan1 1500 172.16.14.0 172.16.14.44 3819 0 1948 0 2 lo0 4136 127.0.0.0 127.0.0.1 916 0 916 0 0 # # lanscan Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPI Path Address In# State NamePPA ID Type Support Mjr# 0/10/0/0 0x00306E0653E8 1 UP lan1 snap1 1 ETHER Yes 119 # This output shows that lan1 is the network interface devoted to vPar cable2 on this server. The lanscan output shows that this interface has a hardware path of 0/10/0/0. The LBA of 0/10 was configured as a component of the vPar when it was created with -a io:0/10/. Unlike the LAN interface on the Core I/O card that was an implied component, this LAN interface is in a separate PCI slot and LBA and therefore had to be specified explicitly when the vPar was created. Running lanadmin on cable1 produces more detailed output related to lan0, as shown in the following listing: # lanadmin LOCAL AREA NETWORK ONLINE ADMINISTRATION, Version 1.0 Mon, Oct 15,2001 14:41:23 Copyright 1994 Hewlett Packard Company.

Let's now run lanadmin on cable2 and see for what LAN interface it produces an output: # lanadmin LOCAL AREA NETWORK ONLINE ADMINISTRATION, Version 1.0 Mon, Oct 15,2001 14:41:23 Copyright 1994 Hewlett Packard Company.

Producing information specific to the vPar in which you issue a command is what you can expect when working at the command line with vPars. Next, let's take a look at a couple of GlancePlus/UX outputs. |
