LUN COMMANDS

The LUN commands enable you to create, delete, list, get information for, and update LUNs.

A LUN represents the presentation of a block device (IoMemory, RAID, or volume) by a target,

which can be queried by remote initiators. Each LUN has a unique serial number that initiators use

for multipath I/O discovery. An initiator group should be given if access control is required; only

those initiators in the given group will be allowed access to the block device presented by the

target.

ION Accelerator does not auto-discover LUNs that you create. In order to view the LUNs, you

need to run

rescan-scsi-bus.sh (OL or RHEL) or Rescan Volumes (Windows host). For

SLES, run

echo - - - > /sys/class/scsi_host/host#/scan <#>, where “#”

indicates the host number based on the current configuration.

lun:create

Creates a LUN.

Syntax

lun:create [options] volume initiatorGroup target(s)

Options

–-repair Indicates repair, after servicing

–-blocksize or –b <integer>

Block size for the LUN. The default is 512B.

Using a random write access pattern with 512B blocks may

significantly impact available system RAM.

--optimized-targets or -o

Create the LUN with NUMA-optimized targets for the specified volume.
