NimbostratusResolv lookup by virtual server name
Hi!
We are trying to resolve some domains using the RESOLV::lookup command on iRules, so we created a virtual server pointing to a pool of DNS servers.
The code we use in the iRule is as follows:
set ips [RESOLV::lookup @vserver_dns -a $host]
But when running, we get the following error message:
Tue Jul 31 17:23:17 EDT 2012 err tmm tmm[7060] 01220001 TCL error: /Common/suppliers - while executing "RESOLV::lookup @vserver_dns -a $host"
So we were needing help to see what we are doing wrong.

the wiki says this was added in BIGIP 10.1, what version are you running?

Can you try setting the virtual server name with the folder:
set ips [RESOLV::lookup @/Common/vserver_dns -a $host]

Aaron, thank you very much!
It would be great to update documentation at https://devcentral.f5.com/wiki/iRules.resolv__lookup.ashx :P
Thanks!
