�S(sQuery the RAID information of certain volume.

        New in version 1.2.

        Query the RAID type, strip size, extents count, minimum I/O size,
        optimal I/O size of given volume.

        This method requires this capability:
            lsm.Capabilities.VOLUME_RAID_INFO

        Args:
            volume (Volume object): Volume to query
            flags (int): Reserved for future use. Should be set as
                lsm.Client.FLAG_RSVD
        Returns:
            [raid_type, strip_size, disk_count, min_io_size, opt_io_size]

            raid_type (int): RAID Type of requested volume.
                Could be one of these values:
                    Volume.RAID_TYPE_RAID0

                        Just bunch of disks, no parity, no striping.
                    Volume.RAID_TYPE_UNKNOWN
                        The plugin failed to detect the volume's RAID type.
                    Volume.RAID_TYPE_MIXED
                        This volume contains multiple RAID settings.
                    Volume.RAID_TYPE_OTHER
                        Vendor specific RAID type
            strip_size(int): The size of strip on each disk or other storage
                extent.
                For RAID1/JBOD, it should be set as sector size.
                If plugin failed to detect strip size, it should be set
                as Volume.STRIP_SIZE_UNKNOWN(0).
            disk_count(int): The count of disks used for assembling the RAID
                group(s) where this volume allocated from.
                For any RAID system using the slice of disk, this value
                indicate how many disk slices are used for the RAID.
                For example, on LVM RAID, the 'disk_count' here indicate the
                count of PVs used for certain volume.
                Another example, on EMC VMAX, the 'disk_count' here indicate
                how many hyper volumes are used for this volume.
                For any RAID system using remote LUN for data storing, each
                remote LUN should be count as a disk.
                If the plugin failed to detect disk_count, it should be set
                as Volume.DISK_COUNT_UNKNOWN(0).
            min_io_size(int): The minimum I/O size, device preferred I/O
                size for random I/O. Any I/O size not equal to a multiple
                of this value may get significant speed penalty.
                Normally it refers to strip size of each disk(extent).
                If plugin failed to detect min_io_size, it should try these
                values in the sequence of:
                logical sector size -> physical sector size ->
                Volume.MIN_IO_SIZE_UNKNOWN(0).
            opt_io_size(int): The optimal I/O size, device preferred I/O
                size for sequential I/O. Normally it refers to RAID group
                stripe size.
                If plugin failed to detect opt_io_size, it should be set
                to Volume.OPT_IO_SIZE_UNKNOWN(0).
        Raises:
            LsmError:

        Usage:
            Query the membership information of certain pool:
                RAID type, member type and member ids.
            Currently, LibStorageMgmt supports two types of pool:
                * Sub-pool -- Pool.MEMBER_TYPE_POOL
                    Pool space is allocated from parent pool.
                    Example:
                        * NetApp ONTAP volume

                * Disk RAID pool -- Pool.MEMBER_TYPE_DISK
                    Pool is a RAID group assembled by disks.
                    Example:
                        * LSI MegaRAID disk group
                        * EMC VNX pool
                        * NetApp ONTAP aggregate

        Version:
            1.2
        Usage:
            This method is dedicated to local hardware RAID cards.
            Create a disk RAID pool and allocate entire storage space to
            new volume using requested volume name.
            When dealing with RAID10, 50 or 60, the first half part of
            'disks' will be located in one bottom layer RAID group.
            The new volume and new pool will created within the same system
            of provided disks.
            This method does not allow duplicate call, when duplicate call
            was issued, LsmError with ErrorNumber.DISK_NOT_FREE will be raise.
            User should check disk.status for Disk.STATUS_FREE before
            invoking this method.
        Parameters:
            name (string)
                The name for new volume.
                The requested volume name might be ignored due to restriction
                of hardware RAID vendors.
                The pool name will be automatically chosen by plugin.
            raid_type (int)
                The RAID type for the RAID group, possible values are:

            If lsm.Capabilities.VOLUME_WRITE_CACHE_POLICY_SET_IMPACT_READ
            is supported(e.g. HPE SmartArray), the changes on write cache
            policy might also impact read cache policy.
            If lsm.Capabilities.VOLUME_WRITE_CACHE_POLICY_SET_WB_IMPACT_OTHER
            is supported(e.g. HPE SmartArray), changing write cache policy
            to write back mode might impact other volumes in the same system.
        Parameters:
            volume (Lsm.Volume)
                The lsm.Volume instance.
            wcp (int)

                        Change to auto mode: use write back mode when
                        battery/capacitor is healthy, otherwise use write

                Indicate that changing to write back mode might impact other
                volumes. For example, on HPE SmartArray, changing to write back
                mode will change all other volumes with auto write cache policy
                to write back mode.

                                                   flags=lsm.Client.FLAG_RSVD)

        Version:
            1.3
        Usage:
            Change the RAM read cache policy of specified volume.
            If lsm.Capabilities.VOLUME_READ_CACHE_POLICY_SET_IMPACT_WRITE
            is supported(like HPE SmartArray), the change on write cache policy
            might also impact read cache policy.
        Parameters:
            volume (Lsm.Volume)
                The lsm.Volume instance.
            rcp (int)
                Could be one of these value:
                    * lsm.Volume.READ_CACHE_POLICY_ENABLED
                        Enable read cache.
                    * lsm.Volume.READ_CACHE_POLICY_DISABLED
                        Disable read cache.
            flags (int, optional):
                Reserved for future use. Should be set as lsm.Client.FLAG_RSVD
        Returns:

            LsmError
                ErrorNumber.NO_SUPPORT
                ErrorNumber.NOT_FOUND_VOLUME
        Capability:
            lsm.Capabilities.VOLUME_READ_CACHE_POLICY_SET
                Allow enabling or disabling read cache policy.
            lsm.Capabilities.VOLUME_READ_CACHE_POLICY_SET_IMPACT_WRITE
                Indicate that changing read cache policy might impact write
                cache policy. For example, on HPE SmartArray, disabling read
                cache will also change write cache policy to write through.
