Re: cannot ping/telnet from linux to storage (DS300 TotalStorage).

Hello,
I connect the management port of controller B of IBM totalStorage
DS300 with a cross cable to a linux machine.
According to DS300 docs, the default IP address of controller B is
192.168.70.124/255.255.0.0.
see 4.4.1 Setup of management ports of TotalStorage DS300 and DS400
in
IBM TotalStorage - DS300 and DS400 / Best Practices Guide.
So I set the linux ip address to 192.168.70.1/255.255.0.0.

while pinging 192.168.70.124 , I power up controller B of
IBM totalStorage. I tried three times this power down and
power up; I get some answers for this ping (about 4 or 5)
and then there are no answers. Also of course there is no
telnet to 192.168.70.124.

Could it be that someone had changed the IP ?
an in case it is so - how can I see the real IP address ?

It seems plausible.

If the thing follows the common practice of probing its
own IP at start with gratuitous ARPs, get an Ethernet
sniffer (tcpdump, Ethereal, Tethereal or Wireshark) and
look for ARP packets with the proper MAC from the IBM box.
