We had issues with viosecure too. The DLPAR was not working on VIOS after applied viosecure with level high. To fix the issue, we applied viosecure only after applied the 2.2.2.3 upgrade. If you apply viosecure after installing the 2.2.2.2 release, the DLPAR does not work on VIOS. There is some APAR about this issue : http://www-01.ibm.com/support/docview.wss?uid=isg1IV50119 In such a situation we usually say in France : "Le mieux est l'ennemi du bien"

*sigh* We had a similar problem, although our VIOS are not in viosecure mode of any kind. We believe someone - for some reason - may have invoked aix expert, which then put a bunch of firewall filters in place, such that every time we tried an LPM, as you found, it kills the RMC connection and LPM fails. We never seemed to lose SSH connectivity to the VIOS, however. Once we deleted the extraneous filters, things returned to normal. These problems can be quite hard to track down!
