Hi,
I have a HP-UX 11.31 Sept 2011 VM running on an Integrity HP-UX 11.31 Sept 2011 host. When the system detects the NIC it is detecting as lan2. I really need this to use lan0 as this VM is a backup system so I need it to be the same as the primary server.
[root@hostname:/]# ioscan -FnC lan
pci:wsio:F:F:F:-1:-1:4294967295:lan:igssn:0/0/1/0:16 60 19 56 0 0 0 6 :2:root.cec_gen.gh2p.igssn:igssn:CLAIMED:INTERFACE:HP IGSSN PCI AVIO LAN Adapter:2:
[root@hostname:/]#
The netconf file is populated using lan0 and has no mention of lan2. I know I can get the interface up by changing the netconf file to use lan2 but I really need the interface to use lan0 so the systems are all the same.
[root@hostname:/]# more /etc/rc.config.d/netconf | grep lan0
INTERFACE_NAME[0]="lan0"
[root@hostname:/]# more /etc/rc.config.d/netconf | grep lan2
[root@hostname:/]#
Any ideas how I can update or force this?
TIA
Solved! Go to Solution.

Re: NIC is being detected as lan2 should be lan0
Thanks for taking the time to respond.
Yeah nwmgr and lanscan, etc all report the PPA as lan2. Just can't seem to get lan0 even though there are only 2 NIC's. Even with one NIC I have the same issue.
[root@hostname:/usr/local/bin]# nwmgr

SolutionThe PPA numbers can be reset or hard coded via the following methods. Thx to HP Support for the assist.
I went with proc 2
-- ioinit -rC lan
-- Updated /etc/rc.config.d/netconf so the PPA number was 0 and 1 again
-- shutdown -r now
-- ioscan -FnC lan showed lan0 and lan1
Procedure-1:
1) Verify current instance number assignment for lan class.
# ioscan -fnNkClan
Class I H/W Path Driver S/W State H/W Type Description
======================================================================
lan 0 0/1/2/0 iether CLAIMED INTERFACE HP PCI-X 1000Base-T Dual-port Built-in
lan 1 0/1/2/1 iether CLAIMED INTERFACE HP PCI-X 1000Base-T Dual-port Built-in
lan 2 0/2/1/0/4/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
lan 3 0/2/1/0/5/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
lan 4 0/2/1/0/6/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
lan 5 0/2/1/0/7/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
2) Generate infile for lan class, which will be used by ioinit
# mkdir /tmp/hp
# cd /tmp/hp
# ioscan -kNf | grep ^lan | awk '{printf "%s %s %s\n",$3,$1,$2}' > infile
3) Edit and modify the infile as per requirements.
# vi infile
After then, change the list from
0/1/2/0 lan 0
0/1/2/1 lan 1 <<<<<<
0/2/1/0/4/0 lan 2
0/2/1/0/5/0 lan 3
0/2/1/0/6/0 lan 4
0/2/1/0/7/0 lan 5
to
0/1/2/1 lan 9 <<<<<<<<<<<
Save file and exit.
4) execute ioinit with the infile
# ioinit -rf ./infile
System will reboot after the completion. Please check again with ioscan after the reboot.
5) Verify new instance number assignment.
# ioscan -fnC lan
Class I H/W Path Driver S/W State H/W Type Description
======================================================================
lan 0 0/1/2/0 iether CLAIMED INTERFACE HP PCI-X 1000Base-T Dual-port Built-in
lan 9 0/1/2/1 iether CLAIMED INTERFACE HP PCI-X 1000Base-T Dual-port Built-in <<< we have lan9 now
lan 2 0/2/1/0/4/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
lan 3 0/2/1/0/5/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
lan 4 0/2/1/0/6/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
lan 5 0/2/1/0/7/0 btlan CLAIMED INTERFACE HP A5506B PCI 10/100Base-TX 4 Port
6) remove old device files if they exist.
Procedure-2:
- You may use following procedure to reassign the instance numbers starting from 0.
From the man page of ioinit(1M):
-C class_name
Forces the kernel to reassign instance numbers starting from 0 for all existing devices with the given class_name. This option must be used with the option. On successful completion the system is rebooted immediately.
- To force it back to start with instance numbers from 0, run:
# ioinit -rC lan
- The server will reboot after the completion. Please check again with ioscan after the reboot.
