After restart system, cannot start sap (and connect via GUI)

We have installed Solution Manager 7.1 on linux64.
After the accident, and reboot the system , stops producing startsap. On the advice of specialists took over running the "startsap <virtualhost>"
At the command prompt , startsap_DVEBMGS00.log startsap.trc and indicated that the launch was successful .
However, neither in the list of processes to be seen dispatcher, or SAP GUI can not connect to the system.
In addition, there is an assumption that just does not start JAVA Instance.
In this regard, there are a number of questions for the esteemed colleagues :
1. on how the logs directory from which you can learn this starts the ABAP and JAVA stacks ?
2 . As can be verified directly from the server ( what commands ) kaktivnost / no system activity ?
3 . Which log files do I need to provide here , you so that you could possibly help me?
