DSH on NIM Server with AIX 7.1

After upgrading my NIM Server to from AIX 6.1 to AIX 7.1, I received the following errors running dsh.

root@nim_server: / # dsh -N ALL date

0042-053 lsnim: there is no NIM object named "lpar_labo1"

The node lpar_labo1 is not defined in NIM database.

I've found than I need to set de DSH_CONTEXT to DSH, to prevent dsh to go to NIM groups, and using my own server groups

root@nim_server: / # export DSH_CONTEXT=DSH

root@nim_server: / # dsh -N ALL date

Other useful Tip to use DSH through any port, not just 22 (Default SSH Port)
