Configuration: Device Mapper Multipath for Linux 191
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 ex am ple :
# 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 MD3600i Series array are now
setup and ready to be used. Future reboots automatically find multipathing
devices along with their partitions.
NOTE: To ensure data integrity protection, reboot a Linux host server attached to
an MD3600i Series storage array using the procedure given below.
