2. ### To Check the Diskless Nodes If you have diskless nodes in your cluster, check the packages and patches installed. Log in to a diskless node as superuser. List the packages installed in the root directory of the diskless node:
       # /opt/SUNWcgha/sbin/nhadm check installation
       OS and Software checking

          64-bit kernel mode                                 OK
          OS release                                         OK

       Local packages

          Package SUNWnhtp9                                  OK

       Shared packages (on /SUNWcgha/swdb)

          Package SUNWjdrt                                   OK
          Package SUNWnhmaj                                  OK

       Patches

       Can take a long time ...

          Patch 112233-03                                    OK
          Patch 112902-06                                    OK
          Patch 112904-01                                    OK
          INST_RELEASE file for shared packages              OK
4. Make a copy of this list of packages and patches because you reinstall only the packages and updated version of patches already installed on the node. The previous list might be slightly different from the actual output for your node. Check for the Watchdog packages:
       # pkginfo SUNWnhwdt SUNWlomu SUNWlomr
5. 2. Check the patches installed in the `/usr` directory of the diskless nodes. Some patches for the diskless nodes are installed in the `/usr` directory, which is mounted from the master node. For a list of these patches, log in to the master node as superuser. Get the list of patches.
          # patchadd -p -S target-OS
          Patch: 112233-01 Obsoletes: 112737-03 113150-03 113156-01 113158-01 \

          Incompatibles: Packages: SUNWcsu
2. where target-OS is `Solaris_8` or `Solaris_9`. ### To Check the Dataless Nodes Perform this procedure if you have dataless nodes in your cluster. Log in to a dataless node as superuser. List the packages and patches installed on the dataless node:
       # /opt/SUNWcgha/sbin/nhadm check installation
       OS and Software checking

          64-bit kernel mode                                 OK
          OS release                                         OK

          Package SUNWjdrt                                   OK
          Package SUNWnhmaj                                  OK
          Package SUNWnhmal                                  OK

4. Make a copy of this list of packages and patches because you reinstall only the packages and updated version of patches already installed on the node. The previous list might be slightly different from the actual output for your node. Check for the Watchdog packages:
