"Serial Relay Agent" Its not CLI causing error

Well fellas,

I have installed the rack and power manager on 1 server and have the serial agent running on 2 servers along with the shutdown agents. I have installed the shutdown agents also on about 20 servers over 2 UPS's and No problems at all.

Then i get to the next cabinet, install the serial lead, install R&P manager and then the fun started. The log is filling up with SRA errors, So surfing around and i see that there is an advisory from HP stating that the SRA sometimes has issues with the CLI on the ILO so i disable the CLI thinking that would solve it but it didnt.

The server its connected to is a DL380 G4 and the UPS is a R5500XR.

Any help will be appreciated because i cant find anything thats different between the servers.

what i have noticed is that i had to install a driver on the other 2 servers but the one i configuring now hasnt asked or picked up the UPS? the R and P manager did pick it up for about 3 or 4 minutes but then the dreaded "Connection Lost to Device" message.

I am assuming this is the steps that you followed?

If the server is not detecting the UPS at all have you verified that nothing else is utilizing the COM port? Maybe try and connect to a switch as a test through hyperterminal.

Check your cable? See if this server can connect to one of your known working UPSs with the cable that it is using as a sanity check.

Re: "Serial Relay Agent" Its not CLI causing error

Yes i followed the steps to that link - Thanks dude.

I have also tried the following

Connecting the ups in cab 3 to the server runing the SRA in cab 2 and low and behold no problems at all. So i have established that there is nothing wrong with the com port on the ups and there is nothing wrong with the cable.

I have now used that cable to connect the ups in cab 3 to the server in cab 3 running the SRA but the relay agent is filling the event logs. Note on this server i have completly disabled the ILO so there is no chance that the cli portion of it is causing problems.

The only difference i can see between the servers is one has EPO AV on it and the other doesnt - but surely thats not it?

Thanks for the reply man its getting very fustrating and in about 1 hour i'm gonna ask my boss to get the snmp option card that should have been purchased with it in the first place lol.

Any other ideas i would really appreciate it.

Oh sorry and yes i verified the com port was free using hyperterminal. i put in the baud rate and the other settings and once i disabled the SRA the HT connected immediately.
