Hi,
Persistant binding!! Upgrade to secure path 3.0F. check VCS is compatible with 3.0F

3.0D or earlier have this problem. 3.0E or above this is fixed. If you want to continue using the 3.0C there are some special steps to make it persistent across reboots.

spmgr update
kmadmin -L swspData
config -M swspData -u

This will make the changes persistent across the reboots

Please read page 13/14/15 of the attachment.

We had this happen during a power outage, and also after we ignited our server.

I am not so sure about updating the securepath as we are on version 3.0E. I would have some good map files of your volume groups. Make sure that you vgexport -p -v -s -m /dev/vgnn.map vgnn (use the -s switch).
