Resources

SUMA

Creates a task to automate the download of technology levels (TL) and service packs (SP) from a fix server.

Must be described in yaml format with the follwoing parameters:

    aix_suma:
      oslevel:  required; specifies the OS level to update to;
                "latest" indicates the latest level of the higher TL among
                the target; based on the fix server, aix_suma will determine
                the actual oslevel necessary to update the targets
                and create the corresponding NIM resource on the NIM server;
                xxxx-xx(-00-0000): sepcifies a TL;
                xxxx-xx-xx-xxxx or xxxx-xx-xx: specifies a SP.
      location: required; if it is an absolute path, specifies the directory where the
                packages will be downloaded on the NIM server;
                if it is a filename, specifies the lpp_source_name
      targets:  required; specifies the NIM clients to update;

                possible values: "download" to download all the fixes and create
                                 the associated NIM resources;
                              or "preview" to execute all the checks without
                                 downloading the fixes.

      targets:    specifies the NIM clients to update;
                  "foo*" designates all the NIM clients with name starting by "foo";
                  "foo[2:4]" designates the NIM clients among foo2, foo3 and foo4;

                  if "lpp_source" is set to "latest_xx" or "next_xx", this parameter
                  is set to "false".
