Lexmark IBM 9077 - Manual (Page 247)

Multiple RS/6000 SPs and Multiple GRFs 229
The media card adapters on the GRF routers should already be up and
running (according to Section 3.7, “Step-by-Step Media Card Configuration”
on page 86 and Section 4.5, “HIPPI Configuration” on page 133). Important
settings are repeated here, nevertheless, to be on the safe side:
On the GRF 1600 (HIPPI card is in slot 8, SP Switch card is in slot 3) check
for the following:
1. The file /etc/grifconfig.conf has the following entries:
gh080 10.50.1.1 255.255.255.0 - mtu 65280
gt030 192.168.14.4 255.255.255.0 - mtu 65520
2. The file /etc/grlamap.conf has the following entry (note that ’0x40’ is a
hexadecimal value equivalent to 64 decimal):
* 0xfc0 0x40 # default mapping of IP for all portcards
3. The file /etc/grarp.conf has the following entry (I-field):
gh080 10.50.1.2 0x03666fc0
4. The file /etc/grroute.conf has the following line:
192.168.13.0 255.255.255.0 10.50.1.2
This sets the correct route to the other SP Switch network over the HIPPI
interface automatically; of course, this route can also be set manually
every time the GRF is rebooted.
5. The SP Switch Router Adapter card is connected to the SP Switch and
configured. Check with SDRGetObjects switch_responds on the CWS and
use Eunfence if needed.
On the GRF 400 (HIPPI card is in slot 0, SP Switch card is in slot 1):
1. The file /etc/grifconfig.conf has the following entries:
gh000 10.50.1.2 255.255.255.0 - mtu 65280
gt010 192.168.13.4 255.255.255.0 - mtu 65520
2. The file /etc/grlamap.conf has the following entry:
* 0xfc0 0x40 # default mapping of IP for all portcards
3. The file /etc/grarp.conf has the following entry (I-field):
gh000 10.50.1.1 0x03555fc0
4. The file /etc/grroute.conf has the following line:
192.168.14.0 255.255.255.0 10.50.1.1
This sets the correct route to the other SP Switch network over the ATM
interface automatically; of course, this route could also be set manually
every time the GRF is rebooted.
