Can no longer connect to serial port

Can no longer connect to serial port

Can no longer connect to serial port

Hi all,
I am an administrator for forty-eight SOlaris servers scattered around the world, I have remote console connectivty via Cisco 2821 terminal servers.  Recently all the devices were moved to new terminal servers but I can no longer get remote console connectivity to fourteen of them.  Most of the servers just give a blank line.  I have had the port and cable changed on two of them with no joy.  One of the servers was local so I risked a reboot (didn't fancy rebooting one of the distant ones as hands-and-eyes support staff are difficult to get hold of and these are production boxes.).  While connected via IP I attempted a reboot, after 20minutes of waiting I decided I'd have to connect directly with my laptop, when I connected the machine was waiting for an ilom login.  After logging in and completing the boot the server was working fine and I could connect via the terminal server.

The boxes are Sun 5220's and I am running Solaris 10.

Any help would be greatfully received as I really don't fancy trying to reboot the other thirteen boxes with nobody onsite...

RE: Can no longer connect to serial port

is there an acl on the cisco device preventing access?

RE: Can no longer connect to serial port

Hi North,
no there isn't I'm afraid, plus the reboot of the one local server did eventually get me access which it wouldn't have done with an ACL in the way.
My current thinking is that there is some sort of stale session still in place from the old terminal server (say some sloppy techy, probably me, left the RC session logged in and just shut the window before the terminal server was disconected and the new one connected.
