Hello.

1. Quantity of plumbed IPoIB interfaces and quantity of IPoIB interfaces 
configured for uDAPL with datadm don't matter.
Initially I plumbed two IPoIB interfaces ibd0 & ibd1 and configured it for 
uDAPL with datadm. "datadm -v" show 2 records - for ibd0 & ibd1.
Next I unplumbed ibd1 and unconfigured uDAPL on it with 'datadm -u' - uDAPL 
didn't work again. uDAPL (ClusterTools & dapltest) didn't work even when I 
unconfigured IPoIB instance of ibd1 with 'cfgadm'
Only when I disabled second port on switch or disconnected it - uDAPL (both 
dapltest & clustertools) was started.

Finally I plumbed & configured for DAT two IPoIB interfaces again and just 
disconnected second port from IB fabric - uDAPL (this test was performed with 
dapltest only) worked well in this situation.

2. I still don't check Infiniband Update 1 on Solaris 10, but I installed patch 
126648-02, that fix the same bugs as IB Update 1, but don't include 'arbel' 
driver. I will check Infiniband Update 1 soon.

3. Unfortunately HPC ClusterTools 8 EA1 docs not decribe how to use Infiniband 
multi-rail configuration, that introduced it release.
I tested HPC ClusterTools 8 EA1 in the IB single-rail configuration with HPL. 
Performance of HPC ClusterTools 8 EA1 was significantly slower than HPC 
ClusterTools 7.1 on the same hardware (about two times slower) ;)

4. I used 'dapltest' from dapl_gamma 3.03 distribution from sourceforge.

Regards,

Denis
