Are io-pkt* and the drivers running?

As mentioned before, io-pkt* is the framework used to connect drivers and protocols. In order to troubleshoot this, use the following pidin command:

$ pidin -P io-pkt-v4-hc mem

Look for the Qnet shared object in the output:

     pid tid name               prio STATE            code  data        stack
  118802   1 sbin/io-pkt-v4-hc   21o SIGWAITINFO      876K  672K  4096(516K)*
  118802   2 sbin/io-pkt-v4-hc   21o RECEIVE          876K  672K  8192(132K) 
  118802   3 sbin/io-pkt-v4-hc   21r RECEIVE          876K  672K  4096(132K) 
  118802   4 sbin/io-pkt-v4-hc   21o RECEIVE          876K  672K  4096(132K) 
  118802   5 sbin/io-pkt-v4-hc   20o RECEIVE          876K  672K  4096(132K) 
  118802   6 sbin/io-pkt-v4-hc   10o RECEIVE          876K  672K  4096(132K) 
            libc.so.2          @b0300000             436K   12K
            devnp-shim.so      @b8200000              28K  4096
            devn-pcnet.so      @b8208000              40K  4096
            lsm-qnet.so        @b8213000             168K   36K

If the output includes an lsm-qnet.so shared object, Qnet is running.
