I am writing a CIM client that talks to the 3PAR storage system. However I am having trouble getting to the main storage class with the Class names defined in SMI-S.
The 3PAR system I am using is a 3PAR-F200.
I checked the CIM service on the system and it shows the below information
3PAR-F200 cli% showcim
-Service- -State-- --SLP-- SLPPort -HTTP-- HTTPPort -HTTPS- HTTPSPort PGVer CIMVer
Enabled Inactive Enabled 427 Enabled 5988 Enabled 5989 2.9.1 3.1.1
I wonder why the state say 'Inactive'. However I can connect to the CIM server using WBEM. My problem is I normally get the main array using the CIM_RegisteredProfile class. In case of 3par altough I can access the Array CIM_registeredprofile class, I cannot get to the storage system asscociated with this class. I use python as my language and here is what I am trying
wconn = pywbem.WBEMConnection('https://172.22.221.30:5989', ('3paradm', '3pardata'), 'root/PG_interop')
# I can successfully connect to this namespace
reg_profiles = wconn.EnumerateInstances('CIM_RegisteredProfile')
# I get the list of all registered profiles. This includes the Server and Array profiles
array = filter(lambda a: a['RegisteredName']=='Array', reg_profiles)
#I get the Array profile instance
sys = wconn.Associators(array[0].path, AssocClass='CIM_ElementConformsToProfile', ResultClass='CIM_ComputerSystem')
#This should give me the StorageSystem instance. however this fails with this error
pywbem.cim_operations.CIMError: (0, "The web server returned a bad status line: ''")
Has anyone faced this issue? Am I doing something wrong here?
A simple EnumerateInstances for the CIM_ComputerSystem class also does not work.
>>> wconn.EnumerateInstances('CIM_ComputerSystem') Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/pymodules/python2.6/pywbem/cim_operations.py", line 404, in EnumerateInstances
**params)
File "/usr/lib/pymodules/python2.6/pywbem/cim_operations.py", line 173, in imethodcall
raise CIMError(0, str(arg))
pywbem.cim_operations.CIMError: (0, "The web server returned a bad status line: ''")
However it does enumerate instances of the TPD_StorageSystem class
wconn.EnumerateInstances('TPD_StorageSystem')
[CIMInstance(classname=u'TPD_StorageSystem', ...)]
Any help is greatly appreciated.
