Dear linux.amrit,

I have a few to questions:-
  • What output/errors do you get?
  • What OS version are you using?
  • Can you not join these up with reference to the files in /dev/disk?

We're all here to learn and getting all the relevant information will help us all. Some of this may well depend on the OS version, so please could you paste the output from uname -a in CODE tags into the thread.


Kind regards,
Robin

NAME
MP_GetMultipathLus - return a list of multipath logical units SYNOPSIS
cc [ flag... ] file... -lMPAPI [ library... ] #include <mpapi.h> MP_STATUS MP_GetMultipathLus(MP_OID oid, MP_OID_LIST **ppList); PARAMETERS
oid The object ID of the plugin or device product object. ppList A pointer to a pointer to an object ID that has type MP_OID_LIST structure. With a successful return, this contains a pointer to an MP_OID_LIST that contains the object IDs of all the (multipath) logical units associated with the specified plugin object ID. DESCRIPTION
The MP_GetMultipathLus() function returns a list of multipath logical units associated to a plugin. When the caller is finished using the list it must free the memory used by the list by calling MP_FreeOidList. RETURN VALUES
MP_STATUS_INVALID_OBJECT_TYPE The oid does not specify any valid object type. This is most likely to happen if an uninitialized object ID is passed to the API. MP_STATUS_INVALID_PARAMETER The ppList is null or specifies a memory area that cannot be written, or when oid has a type subfield other than MP_OBJECT_TYPE_DEVICE_PRODUCT or MP_OBJECT_TYPE_PLUG IN. MP_STATUS_OBJECT_NOT_FOUND The oid owner ID or object sequence number is invalid. MP_STATUS_SUCCESS The operation is successful. MP_STATUS_FAILED The plugin for the specified object ID is not found. MP_STATUS_INSUFFICIENT_MEMORY A memory allocation failure occurred. ATTRIBUTES
