47                      Current pool(also known as sub-pool) is allocated from
48                      other pool(parent pool). The 'raid_type' will set to
49                      RAID_TYPE_OTHER unless certain RAID system support RAID

59                   LSM_POOL_MEMBER_TYPE_POOL,  the 'member_ids' will contain a
60                   list  of  parent   Pool   IDs.    When   'member_type'   is
61                   LSM_POOL_MEMBER_TYPE_DISK,  the 'member_ids' will contain a
62                   list of disk  IDs.   When  'member_type'  is  LSM_POOL_MEM‐
63                   BER_TYPE_OTHER  or  LSM_POOL_MEMBER_TYPE_UNKNOWN,  the mem‐
64                   ber_ids should be  NULL.   Memory  need  to  be  freed  via
65                   lsm_string_list_free.

67       flags       Reserved for future use, must be LSM_CLIENT_FLAG_RSVD.

DESCRIPTION

73       Retrieves the membership information of certain pool:
74           RAID  type,  member type and member ids.  Currently, LibStorageMgmt
75       supports two types of pool: * Sub-pool -- LSM_POOL_MEMBER_TYPE_POOL
76           Pool space is allocated from parent pool.
77           Example:
78               * NetApp ONTAP volume
79
80       * Disk RAID pool -- LSM_POOL_MEMBER_TYPE_DISK
81           Pool is a RAID group assembled by disks.
82           Example:
83               * LSI MegaRAID disk group
84               * EMC VNX pool
85               * NetApp ONTAP aggregate

RETURN

91       Error code as enumerated by 'lsm_error_number'.
92           * LSM_ERR_OK
93               On success.
94           * LSM_ERR_INVALID_ARGUMENT
95               When any argument is NULL or invalid flags.
96           * LSM_ERR_NO_SUPPORT
97               Not supported.
