HyperFabric configuration

Marius Pana_1 — Mon, 22 May 2006 07:31:03 GMT

Hi all,

Ive just set-up a point-to-point configuration between 2 rc1620's. Everything seems ok except for the fact that it is not clear what I should write in /etc/hosts. I have added the ip addresses which I gave to the HP's but when I try to clic_probe them it says host unknown. If I clic_diag the system name it works fine. Also if I just ping the addresses it work. Any ideas on whats going on?

Here is my /etc/hosts on sric-hub1:

99.100.1.169 sric-hub1.bnr.ro sric-hub1 # this is lan0
192.168.100.1 sric-hub1.bnr.ro.vip sric-hub1.vip # this is clic0 on localhost
192.168.100.2 sric-hub2.bnr.ro.vip sric-hub2.vip # this is clic0 on second host

The file is the same on sric-hub2 and pinging between sric-hubX-vip works but clic_probe sric-hubX-vip does not.

Many thanks!

Hi,

Can you ping on IP adress, instead of hostname?

Check

/etc/resolv.conf
/etc/nsswitch.conf

I can ping on ip-address and hostname. I just cant use clic_probe with the value I have set in /etc/hosts for the clic interfaces.

Here is the results of ping and clic_probe:

bash-3.00# ping sric-hub1-vip

Hi,
by the Managing Hyperfabric Manual:

You have this situation:

node1 with clic0_1
node2 with clic0_2

To test local connettivity:

nodo1:clic_probe -l -c clic0_1

If you need to verify communication with the other node:

clic_probe node2

To test connectivity with nodo2 and nodo1 using the clic0_1 on the nodo1:

clic_probe node2 -c clic0_1

Hope this help you

Enrico

I have the document but something is not very clear to me..obviously 8-)

# sric-hub1 /etc/hosts
99.100.1.169 sric-hub1.bnr.ro sric-hub1
99.100.1.170 sric-hub2.bnr.ro sric-hub2
192.168.100.1 sric-hub1-vip.bnr.ro sric-hub1-vip
192.168.100.2 sric-hub2-vip.bnr.ro sric-hub2-vip

# sric-hub2 /etc/hosts
99.100.1.170 sric-hub2.bnr.ro sric-hub2
99.100.1.169 sric-hub1.bnr.ro sric-hub1
192.168.100.1 sric-hub1-vip.bnr.ro sric-hub1-vip
192.168.100.2 sric-hub2-vip.bnr.ro sric-hub2-vip

I do not have clic0_1 and clic0_2, it gives me an error. I should be able to do the following from sric-hub2:

# clic_probe sric-hub2-vip and it should work. Un fortunately it does not with the following error:
bash-3.00# clic_probe sric-hub2-vip
CLIC_PROBE: 256 byte packets
Source adapter id: sric-hub1.bnr.ro:clic0
Target adapter id: :

# I do not know if this is normal behavior bu t why does sric-hub2 respond?

bash-3.00# clic_probe sric-hub2
CLIC_PROBE: 256 byte packets
Source adapter id: sric-hub1.bnr.ro:clic0

Once we start using the interconnect what do I specify: sric-hub2 or sric-hub2-vip? sric-hub2 is the ethernet which is totally different IP.!?

Many thanks for all the help!

Enrico P. — Mon, 22 May 2006 09:55:31 GMT

OK,
the names clic0-1 clic0_2 were for examples purpouse.

I don' t know the hyperfabric command but for me you test you need is the follow:

From sric-hub1

sric-hub1: clic_probe sric-hb2
sric-hub1: clic_probe -l -c sric-hub1-vip
sric-hub1: clic_probe sric-hb2 -c sric-hub1-vip

From sric-hub2

sric-hub1: clic_probe sric-hb1
sric-hub1: clic_probe -l -c sric-hub2-vip
sric-hub1: clic_probe sric-hb1 -c sric-hub2-vip

If this work fine you are OK

Re: HyperFabric configuration

Marius Pana_1 — Mon, 22 May 2006 10:08:15 GMT

Still fails.

>sric-hub1: clic_probe sric-hb2
This command works

>sric-hub1: clic_probe -l -c sric-hub1-vip
This command fails with :

Local Loopback: Source and Target Adapter ID: sric-hub1.bnr.ro:

The adapter sric-hub1-vip is unknown

>sric-hub1: clic_probe sric-hb2 -c sric-hub1-vip
Same as above

Re: HyperFabric configuration

Enrico P. — Mon, 22 May 2006 10:22:13 GMT

Fail also with the domain name?

From sric-hub1

sric-hub1: clic_probe sric-hub2
sric-hub1: clic_probe -l -c sric-hub1.bnr.ro.vip
sric-hub1: clic_probe sric-hb2 -c sric-hub1.bnr.ro.vip

From sric-hub2

sric-hub1: clic_probe sric-hub1
sric-hub1: clic_probe -l -c sric-hub2.bnr.ro.vip
sric-hub1: clic_probe sric-hb2 -c sric-hub2.bnr.ro.vip

Re: HyperFabric configuration

Enrico P. — Mon, 22 May 2006 10:23:47 GMT

Have you created the configuration file /etc/rc.config.d/clic_global_conf with the clic_init command?

Enrico

Re: HyperFabric configuration

Marius Pana_1 — Mon, 22 May 2006 12:07:43 GMT

It fails with the fqdn as well. The configuration file was created with clic_init.

I am not finding much information about this issue anywhere. It is all very strange...

Enrico P. — Tue, 23 May 2006 03:27:29 GMT

Hi,
news about the problem?

Seems the card are not correctly configured
Is the output of the command
ioscan -nf -C clic
coorect?
Can you post the file /etc/rc.config.d/clic_global_conf?

Enrico

Re: HyperFabric configuration

Marius Pana_1 — Tue, 23 May 2006 03:35:18 GMT

No news. Here is the information you requested. I am starting to think that this is normal behavior?

sric-hub1:

clic 0 0/3/1/0 clicd CLAIMED INTERFACE PCI Network (14c18043)

Class I H/W Path Driver S/W State H/W Type Description
==================================================================
clic 0 0/3/1/0 clicd CLAIMED INTERFACE PCI Network (14c18043)
/dev/clic0

here is the output of clic_global_conf:
bash-3.00# cat /etc/rc.config.d/clic_global_conf

# clic_global_conf: Multicomputer Interconnect Configuration Values
#
# INTERFACE_NAME: Network Interface name. HyperFabric supports a maximum of
# eight interfaces per system.
#
# IP_ADDRESS: IP address in decimal-dot notation (e.g., 192.1.2.3)
#
# BCOMPAT_ENABLED: Network Interface is set up such that HF communication
# with previous HF software releases is allowed.
#

INTERFACE_NAME[0]=clic0
IP_ADDRESS[0]=192.168.100.2
BCOMPAT_ENABLED[0]=N

Thanks for all of your help. Ireally appreciate it.

Run the command

clic_stat -d VRID

for to see the Adapter ID

The output of the command show:

Source adapter id: sric-hub1.bnr.ro:clic0
Target adapter id: sric-hub2.bnr.ro:clic0

It seems that clic0 is sric-hub1.bnr.ro
but clic0 should be sric-hub1.bnr.ro.vip

Re: HyperFabric configuration

Enrico P. — Tue, 23 May 2006 03:47:39 GMT

At this point I think we are trying with a wrong sintax command. Try

From sric-hub1

sric-hub1: clic_probe sric-hub2
sric-hub1: clic_probe -l -c clic0
sric-hub1: clic_probe sric-hub2 -c clic0

From sric-hub2

sric-hub1: clic_probe sric-hub1
sric-hub1: clic_probe -l -c clic0
sric-hub1: clic_probe sric-hub2 -c clic0

Enrico

Re: HyperFabric configuration

Marius Pana_1 — Tue, 23 May 2006 03:56:44 GMT

All of the above commands worked but they worked from the beginning. What doesnt work is:

sric-hub1: clic_probe sric-hub2-vip -c clic0
sric-hub1: clic_probe sric-hub2-vip.bnr.ro -c clic0

and vice versa from sric-hub2..

Re: HyperFabric configuration

Enrico P. — Tue, 23 May 2006 05:05:11 GMT

Proably the command known the hostname of the servers connect with the hyperfabric and not work with the interace name in the /etc/hosts.
So how you said probably it is the normal behavior.

Good work

Enrico

marie-noelle jeanson_1 — Tue, 23 May 2006 14:03:22 GMT

Marius,

First, the user doc does say that:
check your /etc/hosts file-when you are using files for host name look up-to
ensure that the entries for all of the systems are in the correct format:
the official host name, which is the full domain extended host name, and any
alias names. For example:

IP_address bently6.corp3.com bently6
IP_address bently4.corp7.com
test1
IP_address bently2.corp4.com test3

So that should work.

Isn't your probelm that you are using sric-hub1-vip instead of sric-hub1.vip as you defined in /etc/hosts for your names?

Re: HyperFabric configuration

Marius Pana_1 — Tue, 23 May 2006 18:16:54 GMT

Marie,

I misstyped them at the begining of the post. The correct version I provided a few posts later:

# sric-hub1 /etc/hosts
99.100.1.169 sric-hub1.bnr.ro sric-hub1
99.100.1.170 sric-hub2.bnr.ro sric-hub2
192.168.100.1 sric-hub1-vip.bnr.ro sric-hub1-vip
192.168.100.2 sric-hub2-vip.bnr.ro sric-hub2-vip

# sric-hub2 /etc/hosts
99.100.1.170 sric-hub2.bnr.ro sric-hub2
99.100.1.169 sric-hub1.bnr.ro sric-hub1
192.168.100.1 sric-hub1-vip.bnr.ro sric-hub1-vip
192.168.100.2 sric-hub2-vip.bnr.ro sric-hub2-vip

Many thanks.
