[Libstoragemgmt-devel] Where are the CIM_SCSIProtocolController(s) from? FW: [Help]How can I create the SPC only with InitiatorPortIDs by pywbem? Is there any example for this?

Hi, Gris and Tony

Libstoragemgmt does not create the 'CIM_SCSIProtocolController'.

However, the CIM_SCSIProtocolController is used in the function _get_access_groups() in smis.py.

Where are the CIM_SCSIProtocolController(s) from?


def _get_access_groups(self, property_list=None):
"""
Return a list of CIM_SCSIProtocolController.
Following SNIA SMIS 'Masking and Mapping Profile':
CIM_ComputerSystem
|
| CIM_HostedService
v
CIM_ControllerConfigurationService
|
| CIM_ConcreteDependency
v
CIM_SCSIProtocolController
"""

I tried to create the CIM_SCSIProtocolController with InitiatorPortIDs, but it failed.

conn.EnumerateInstances('CIM_ProtocolControllerMaskingCapabilities')[0].items()

[(u'SPCSupportsDefaultViews', False), (u'ElementName', u'XVE Storage System Masking Capabilities'), (u'ProtocolControllerSupportsCollections', False), (u'ProtocolControllerRequiresAuthorizedIdentity', False), (u'ExposePathsSupported', True), (u'OneHardwareIDPerView', False), (u'InstanceID', u'210235G6LPZ0C3000033:196609:7:Nex_ProtocolControllerMaskingCapabilities'), (u'UniqueUnitNumbersPerPort', False), (u'PortsPerView', 4L), (u'SPCAllowsNoLUs', True), (u'SPCAllowsNoInitiators', True), (u'ClientSelectableDeviceNumbers', True), (u'MaximumMapCount', 8L), (u'ValidHardwareIdTypes', [2L, 5L]), (u'SPCAllowsNoTargets', True), (u'PrivilegeDeniedSupported', False), (u'CreateProtocolControllerSupported', False)]
Can anyone kindly tell me that how the ExposePaths method was invoked to create the CIM_SCSIProtocolController?

Sincerely,

Xiaozhen

Hi, Gris and Tony
Libstoragemgmt does not create the ‘CIM_SCSIProtocolController’.

Regarding creating SPC, that was documented in "Group Masking and
Mapping" profile. Since we got no support vendor yet, I simply return no
support when user call access_group_create() on SMI-S plugin.

Post by Qixiaozhen
Can anyone kindly tell me that how the ExposePaths method was invoked
to create the CIM_SCSIProtocolController?

You might try "smi-s-developers-***@googlegroups.com" mailist for SNIA
SMI-S related questions.

Hope that helps.
