Creating a file system for the volume

 

  1. Select a volume that has no mappings:

    prod-linux1-vol-20140702-1400 dm-5 - 9.00 12 3
  2. Run:

    infinihost volume create-filesystem dm-5

    The result is:

    Creating filesystem ... OK

Mounting a volume

Set a mount point to a volume that has a file system.

  1. Run the command with the following arguments:
    • Volume name
    • Mount point
infinihost volume mount dm-4 /mnt –y

The output is:

Mounting filesystem ... OK

Unmounting a volume

Disconnect the volume from the file system.

  1. Run the command with the following arguments:
    • Volume name
infinihost volume unmount dm-4 /mnt –y

The output is:

Volume unmounted

Unmapping a volume

Unmap a volume to disconnect it from the host. The volume remains on InfiniBox and can be connected to the host, or to other hosts.

This command accepts the device name or the mount point as an input (and does not accept the name of the volume as it is seen on InfiniBox).

  1. Run the command with the following arguments:
      • Volume name
infinihost volume unmap vol-1 –y

The output is:

Volume "vol-1" (id 82255) successfully unmapped

Speed testing the volume

The output of the command specifies:

  • Performance test results:
  • Path # 
  • HCTL – an identifier of the host, channel, target and LUN 
  • Initiator WWN 
  • Target WWN 
  • NodeID 
  • PortID
  • Average throughput and average IOPS:

Using the CLI

Run:

infinihost volume speedtest dm-4 --duration=20

The output is:

Running performance test on /dev/mapper/mpathbm
