Yes....I've did this a couple of weeks ago and the APPENDIX F instructions
in the RHEL Install guide worked fine...BUT this was an LPAR situation....

I've got a couple of followup questions...maybe you'll find this as you
work with RHEL4.

Where does RHEL4 store the static route table?
Also, now do you DELETE a 2nd interface.

One caveat about RHEL4...we tried using the  system-config-network
to configure a 2nd interface and I ended up without any network!
Had to fix it via sed....
Don't know if it was the script or user error...

Subject
Adding a new interface to a RHEL4 system






Hello list,

Has anyone been able to add a second interface to a RHEL4 system? I am
trying to add an eth1. I have a other QDIO triplets defined besides the
primary triplet being used by eth0. For example, the VM user ID name TEAMA
has virtual device 1600 as the starting device address of a VSWITCH NIC.
The kernel recognizes them as they show up as directories under
/sys/bus/ccw/drivers/qeth

However, if I echo a "1" to /sys/bus/ccw/drivers/qeth/0.0.1600/online, the
value remains 0.  Similarly the "chccwdev -e" command fails:
# chccwdev -e 0.0.1600
Setting device 0.0.1600 online
Failed

>From a 3270 session, the following shows the status of the device:
#cp q 1600-1602
00: OSA  1600 ON NIC  1600  UNIT 000 SUBCHANNEL = 001
00:      1600 QDIO-ELIGIBLE       QIOASSIST-ELIGIBLE
00: OSA  1601 ON NIC  1600  UNIT 001 SUBCHANNEL = 001
00:      1601 QDIO-ELIGIBLE       QIOASSIST-ELIGIBLE
00: OSA  1602 ON NIC  1600  UNIT 002 SUBCHANNEL = 001
00:      1602 QDIO-ELIGIBLE       QIOASSIST-ELIGIBLE

#cp q vswitch vsw1 det
...
00:     Adapter Owner: TEAMA    NIC: 1600  Name: UNASSIGNED

#cp q vswitch vsw1 accesslist
...
TEAMA (is in the list)

Any help will be appreciated.
