You may need to take the row out of service to chante the name. See the description clause of the RowStatus TC in http://www.ietf.org/rfc/rfc2579.txt for the gory details, which point you to the MIB you are using, which should document the extra logic it uses for row modification. Just because a column is writable does not mean it can be changed at any time.
HTH,

This may be an implementation issue.
Where did the code for this MIB module come from?
[I'm pretty sure it's not one of ours!]
It might be worth talking to the vendor about this.

The Foundry MIB was downloaded from src: http://www.notarus.net/networking/foundry_snmp.html

Did you try the suggestion in the first section of that page?

You mean "snmpset", right? Otherwise, I've found your problem...

It can be tough to work through these things sometimes. The web page you pointed to is very helpful, though, and strongly suggests you should be able to manage through SNMP.
Try this:
$ snmpset -v1 -c rwcommunity 10.10.10.253 . snL4RealServerRowStatus.1 i notInService snAgGblPassword.0 s my-password
$ snmpset -v1 -c rwcommunity 10.10.10.253 . snL4RealServerName.1 s my-new-server-name snL4RealServerRowStatus.1 i active snAgGblPassword.0 s my-password

Just so I'm clear - you are up and running? You must delete the rows to reconfigure the device, correct?
Thanks,
