== Initiator config ==

{{Admon/important|Kernel Update Needed|The current kernel does not support iSCSI transport.}}

Host is OpenRD

# Install the iscsi-initiator-utils package.
# Placed "InitiatorName=iqn.2000-10.ca.on.senecac.hongkong" in /etc/iscsi/initiatorname.iscsi
# Start the iscsi and iscsid services.
# Discover the remote targets: iscsiadm -m discovery -t sendtargets -p hongkong:3260
# List the targets: iscsiadm -m node -- the remote target(s) should be shown.
# Login to the targets: iscsiadm -m node -l
# You will now have an additional scsi disk device. Use this as one element of a RAID-1 array, using local storage (an LV or a looped-back file) as the other element.
# Mount the new RAID-1 array and create a filesystem on it. Place some files there.
# Unmount the filesystem, stop the array, log out of the iSCSI disk (iscsiadm -m node -u).
# Verify that the filesystem can be locally read on the machine hosting the target.

== PATA/USB Config ==

* PATA drive connected via USB
* Device is /dev/sda1 if no other storage is connected

== Target Config ==

* Host is HongKong
* IQN is "InitiatorName=iqn.2000-10.ca.on.senecac.hongkong"
* Target is "target0" which is connected to the LV HongKong/arm1iscsi, size 2GB
