HMC version have to be set because v3 and v4 are not compatibile. It is possible to auto-detect version (lshmc -V) but this is quite slow to do it in each fencing operation. Default value is '4' because we don't want to change previous behaviour. It does not mean that it should not work with HMC v5, v6 - we just need to mark them. Command prompt option was set to default value but missing in device's options. Older LPAR has different prompt so it was added to default one. If you wish to add your own prompt that remember that $ has to be written as '\$'. --- fence/agents/lib/fencing.py.py | 6 +++ fence/agents/lpar/fence_lpar.py | 77 +++++++++++++++++++++++++-------------- 2 files changed, 56 insertions(+), 27 deletions(-) diff --git a/fence/agents/lib/fencing.py.py b/fence/agents/lib/fencing.py.py index 7b7f8d5..9cd6bc8 100644 --- a/fence/agents/lib/fencing.py.py +++ b/fence/agents/lib/fencing.py.py @@ -122,6 +122,12 @@ all_opt = { "longopt" : "drac-version", "help" : "-D, --drac-version= Force DRAC version to use", "order" : 1 }, + "hmc_version" : { + "getopt" : "H:", + "longopt" : "hmc-version", + "help" : "-H, --hmc-version= Force HMC version to use: 3, 4 (default)", + "default" : 4, + "order" : 1 }, "ribcl" : { "getopt" : "r:", "longopt" : "ribcl-version", diff --git a/fence/agents/lpar/fence_lpar.py b/fence/agents/lpar/fence_lpar.py index 44b3a71..53f8f60 100644 --- a/fence/agents/lpar/fence_lpar.py +++ b/fence/agents/lpar/fence_lpar.py @@ -21,19 +21,30 @@ BUILD_DATE="" #END_VERSION_GENERATION def get_power_status(conn, options): -
