lan card issue .

[CHAKRADHAR_1]

hi guys,

i,m facing problem in our few of server that there fc lan goes down, abruptly. ask to the network team they suggested it is ok.

can you all suggest what do ineed to do to resolve this problem. it is not coming up with the ifconfig lan0 up.

[Steven E. Protter]

Shalom,

First determine if the problem is local or not. I doubt its local because it effects multiple machines.

Examine /var/adm/syslog/syslog.log for problems and bring the output to your network folks.

Any time an issue like this hits multiple machines its nearly 100% of the time not a problem on the machines.

Sounds like the SAN/FC network is crashing or having an intermittancy problem such as lip storm etc.

hi stevan,

thank for reply.

but there is no error in syslog for network.
in syslog.log. can any body put more focus on this.

[gigiz]

Can you try to do
ioscan -fnCfc
look the output
then the fc command
fcmsutil /dev/... for analize the fc status ...
Attach the output of command ...

[Jollyjet]

Hi,

Post the output of netstat -rn and lanscan and ioscan -fnC lan.

netstat will give you the total out of the network card's you have if fc lan was not there in lan0 it will show you where it is post the out put we will explain you.

try insf -C lan and check it out.

[Rasheed Tamton]

Hi Chakradhar,

You say fclan (LAN?)
-What does the lanscan shows - are these cards up
-Check also the cards with the lanadmin
-linkloop -v


-Do you have Support Tools Manager installed. Does it show any errors

-Is your patch/firmware level up to date on these servers

FC (SAN)

-Are these servers connected to the same FC Switch/Hub
-Is your patch/firmware level up to date on these servers

#/opt/fcms/bin/fcmsutil /dev/td2 devstat all
#fcmsutil /dev/td1 stat -s (short statistics)

Check the enable/disable option of fcmsutil.

Hi Chakradhar,


lanscan shows it is down:
>/0/0/0 0x001083FC0326 1 DOWN lan1 snap1 2 ETHER Yes 95

You are talking about Lan (it is not fc - it is ether).

Pleae give us the outputs of:
ioscan -fnClan
lanadmin -x 1
lanadmin -x 0
linkloop 0x001083FC0326 (MAC of lan1)

Do you see any errors in syslog.log or dmesg

[Rasheed Tamton]

>it is not coming up with the ifconfig lan0 up.

>>1/0/0/0 0x001083FC0326 1 DOWN lan1 snap1 2 ETHER Yes 95


Did you use
ifconfig lan1 up

[CHAKRADHAR_1]

hi all,

it is not coming with ifconfig lan1 up.

i hope this will help you to dignost the problem

[Rasheed Tamton]

Try this again:

linkloop -i 1 -n 100 0x001083FC0326

(-i 1 lan1 ; -n 100 count no. of frames to transmit)

[CHAKRADHAR_1]

Hi Rasheed,

i,m getting following error.

[Rasheed Tamton]

Hi Chakradhar,

Try without the count option.

linkloop -i 1 0x001083FC0326

[Sandman!]

Please post the output of the following command here:

# ioscan -funC lan

Do you know what type of NIC card it is make/model; what h/w path it is on; kind of server and OS version too would help?

[CHAKRADHAR_1]

it is here..

[Rasheed Tamton]

Hi Chakradhar,

Can you do a reset the lan1 card from lanadmin menu and do ifconfig lan1 up afterward. Does it come up

How is your patch level on this particular system. I doubt whether you might need a patch for this problem. A4926A is not the latest gelan model also.

Do you have the same type of card on any other system. If it works there, is it the same OS version, patch level, cable, etc.

10.100.58.44 (lan1) 10.100.58.16 (lan1)

Can you explain this?

[Sandman!]

Please post the output of the commands below in order to identify the server this NIC is installed in and the OS its running.

# model
# uname -a

The problem maybe at the switch side. Have you tried to see if the network switch can talk to your card? Make sure you are upto date on the firmware for the NIC by examining the output of the following:

# what /stand/vmunix | grep gelan

[NMory]

Chakradhar:

What about the model of you server and OS version? Maybe is a compatibility issue (hardware speaking)

Try to find a support matrix for LAn cards and PARISC servers.

NM.

[NMory]

The A4926A only runs 1000mb (1gb) full-duplex and will not autonegociate. Check this settings in your network.

hi,

here is details.

it was working fine 10-12 days back for few months.

[CHAKRADHAR_1]

this was the due to patch problem.

After loading the reccomanded patch from HP. problem has been rectified.

thankx guys for your valuable efforts.

[conrad heyns]

Hi Chakradhar,

Which Patch resolved the problem you had?

Conrad.
