Configuration: Device Mapper Multipath for Linux 201

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:

# 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.

Blacklist Local Drive in Multi-path Driver

If your multipath drivers are connecting to storage area networks (SANs), it

may be useful to be able to exclude or "blacklist" certain devices in your

/etc/multipath.conf file. Blacklisting prevents the multipath driver from

attempting to use those local devices.

To blacklist a local drive or device:

Run the

multipath -l

command to determine the local drive or

device WWID (World-Wide Identifier) or vendor/model string.

Edit the

/etc/multipath.conf

file as follows:

blacklist {

wwid drive_wwid

…

}
