Verifying SMC-D requirements on each node

Check whether all requirements are met before you configure SMC-D on IBM Storage Scale.

1. Verify whether a node meets SMC-D requirements by running SMC-D Prerequisites Verification Tool tssmcdnodeverify. It is available on Linux® on Z nodes only. The full path is /usr/lpp/mmfs/bin/tssmcdnodeverify.

   # tssmcdnodeverify

   Verifying ISM devices ...
   IBM Internal Shared Memory (ISM) virtual PCI device
   The node gpfs01.domain.com is ready for SMC-D

2. Verify whether a node is running on a specific IBM Z® central processor complex (CPC) by using an optional -c parameter.

   # tssmcdnodeverify -c M123

3. Verify whether a node can establish an SMC-D connection to other nodes.

   # mmnetverify smcd

   A sample output is as follows:

   gpfs01 checking communication with node gpfs02.
     Operation smcd: Success.
   gpfs01 checking communication with node gpfs03.
     Operation smcd: Success.
   gpfs01 checking communication with node gpfs01.
     Operation smcd: Success.
