The NetBSD iSCSI HOWTO
|
|
======================
|
|
|
|
This document is intended to tell you how to set up an iSCSI target on
|
|
a NetBSD host, so that block storage can be presented to the network.
|
|
It then goes on to show how to connect to that storage using the
|
|
Microsoft iSCSI initiator (version 1.06, running on Windows XP).
|
|
|
|
|
|
1. Configuring the NetBSD iSCSI target
|
|
======================================
|
|
|
|
1.1. Decide what storage will be presented
|
|
|
|
The iSCSI target serves up block storage to clients on the network.
|
|
These clients are called "initiators". Firstly, we must decide how
|
|
much storage we are going to serve up, and for this document, we
|
|
will serve up 100 MB. It will be in a file called /tmp/iscsi-target0.
|
|
|
|
So we must first edit /etc/iscsi/targets, so that it contains the
|
|
following lines:
|
|
|
|
# extent file or device start length
|
|
extent0 /tmp/iscsi-target0 0 100MB
|
|
|
|
# target flags storage netmask
|
|
target0 rw extent0 0/0
|
|
|
|
The extent definition tells the file which is used as backing
|
|
store. It is persistent, so that the target can serve up the
|
|
same storage after reboot. Its length is 100 MB, and there is
|
|
no offset into the file for the start of the extent. (An offset
|
|
is useful if you need to skip over MBRs, or disklabels).
|
|
|
|
The extent is mounted read-write by "target0", and is served up
|
|
to any host (the 0.0.0.0/0 netmask).
|
|
|
|
1.2. Start the iscsi-target
|
|
|
|
Issue the command:
|
|
|
|
# /etc/rc.d/iscsi_target forcestart
|
|
|
|
and you should see the messages from the iscsi-target:
|
|
|
|
Starting iscsi_target.
|
|
Reading configuration from `/etc/iscsi/targets'
|
|
target0:rw:0/0
|
|
extent0:/tmp/iscsi-target0:0:104857600
|
|
DISK: 1 logical units (204800 blocks, 512 bytes/block), type iscsi fs
|
|
DISK: LU 0: 100 MB disk storage for "target0"
|
|
TARGET: TargetName is iqn.1994-04.org.netbsd.iscsi-target
|
|
|
|
1.3 You're done!
|
|
|
|
Congratulations - your iSCSI target is now up and running and
|
|
serving blocks to initiators.
|
|
|
|
|
|
|
|
2. Configuring the Microsoft iSCSI initiator, version 1.06
|
|
==========================================================
|
|
|
|
Please see the relevant documentation on setting up iSCSI initiators.
