get_block_for_drive

Gets a block device corresponding to drive.

The returned block device, if any, is for the whole disk drive, e.g. a partition block device is never returned.

Set get_physical to true if you need a block device that you can send low-level SCSI commands with (for multipath, this returns one of the physical paths). Set it to false if you need a block device that you can read/write data with (for multipath, this returns the mapped device).

Parameters:

this	A Client.
drive	A Drive.
get_physical	true to get a physical device, false to get the logical device.

Returns:

A Block or null if the requested kind of block device is not available - use unref to free the returned object.
