SAN switch serial access

[Leandro Constante_2]

I've executed "msPlMgmtActivate", and after that I am unable to access my switch by telnet,
and when I put an notebook on the serial port, nothing happens.

Nmap shows:

[root@leandroc download]# nmap -P0 10.0.12.191

Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2004-10-15 16:56 BRT

The switch is an Compaq Storageworks SAN switch 8.

Any sugestions ?

Thanks.

just an idea: try to log on the lan with telnet and reset the parameter to see if it solve your problem

It is not accepting telnet connections. I did an tcpdump, and the packets go to the
switch, but do not return from it.

The switch and my host are on the same lan, no firewalls in the middle.

Try Browsing to the device rather than Telnet. But I don't know if there's a way of switching this off from the Browser.

Is there just one switch in the Fabric? If not, you should be able to issue the msPlMgmtDeActivate command from another switch.
