HP-UX Installation

Hardware and Software Installation Procedure

•Installation is complete when you have successfully run linkloop, ping and netstat. To configure remote systems, see the Ethernet Support Guide available on the web at http://docs.hp.com. Do this step only if remote systems have not been previously configured.

•Optionally, if you want to verify that the iether driver appears for each installed card, enter: ioscan -f

The ioscan output might look like the following:

Class I H/W Path Driver S/W State H/W Type Description

lan 3 1/10/0/1 iether CLAIMED INTERFACE HPA7011A PCI/PCI-X 1000Base-SX 2Port GigEAdapter

The third column shows the hardware path of the slot in which the card is installed. This path will be different for each installed card.

Optional Step: Configure Jumbo Frames Size

NOTE

Jumbo frames are supported only at 1000 Mbit/s.

•Jumbo frames for the iether driver on HP-UX 11i v 1.0 have mtu_size in the range of 1501-9000 bytes.

If you are using Jumbo Ethernet frames, ensure that all end stations on a given LAN* have the same maximum transmission unit (MTU) setting. However, switch ports in your LAN can have any MTU setting greater than or equal to the end station’s MTU. (*Note: here “LAN” means that the end stations do not have any routers or layer 3 switches in between them.)

•Obtain the PPA number of the card by entering lanscan.

•Choose one of two configuration methods that will permanently save your configuration.

—use the GUI-based system admin manager (SAM).

To use SAM, type sam at the HP-UX system prompt; then double-click Networking and Communications, and then Advanced Configuration--see Ethernet Support Guide for details, and then do the steps for verifying the MTU size; or

edit the following configuration file using an editor such as “vi”:

/etc/rc.config.d/hpietherconf.

Set the mtusize by editing HP_IETHER_MTU[0]=mtusize, and insert the proper interface name: HP_IETHER_INTERFACE_NAME. When the system reboots, the interface will be configured for jumbo frame operation.

•Verify MTU change by entering netstat -rn. If MTU has not changed, enter the following commands: $ifconfig lan PPA_number unplumb

$ifconfig lan PPA_number ip_address netmask netmask up

•To check (or verify) the current Ethernet frame size, enter: $lanadmin -mPPA_number

An alternative way to temporarily** configure jumbo frame size is to enter:

lanadmin -Mmtu_size PPA_number.

The PPA_number is the one we obtained from the output of lanscan. For the iether Gigabit Ethernet driver, the MTU value must be a value between 1501 and 9000 (for Jumbo Frames).

**Note: using lanadmin will not preserve your settings across reboots.
