On SLES 11.x hosts, a partition node has the format /dev/mapper/mpath<x>-part<y>, where <x> is letter(s) assigned to the multipathing device and <y> is the partition number.

On SLES 10.3 hosts, a partition node has the format /dev/mapper/mpath<x>_part<y>, where <x> is the letter(s) assigned to the multipathing device and <y> is the partition number.

NOTE: After creating a partition on a multipathing device, all I/O operations, including file system creation, raw I/O and file system I/O, must be done through the partition node, and not through the multipathing device nodes.

Create a File System on a Device Mapper Partition

Use the standard mkfs command to create the file system on the newly created Device Mapper partition

For example:

#mkfs –t <filesystem type> /dev/mapper/<partition node>

where <partition node> is the partition on which the file system is created.

Mount a Device Mapper Partition

Use the standard mount command to mount the Device Mapper partition, as shown below.

# mount /dev/mapper/<partition_node> <mounting_point>

Ready for Use

The newly created virtual disks created on the MD3200 Series array are now setup and ready to be used. Future reboots automatically finds multipathing devices along with their partitions.

Important Information About Special Partitions

When using Device Mapper with the MD3200 Series array, all physical disks are assigned a disk device node. This includes a special device type used for in-band management of the MD3200 Series array, known as the Access Disk or Universal Xport device.
