HyperFabric configuration

[Marius Pana_1]

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

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

256 bytes: seq_num = 2. Packet Acknowledged.

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!

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

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

[Enrico P.]

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

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