The iscsi-manager can be installed independently from the framework ;)

Exposing a vDisks over iSCSI

Open vStorage allows to expose vDisks over iSCSI for seamless integration with Bare Metal servers or Virtual Machines.

Enterprise Edition

In the Open vStorage Enterprise Edition exposing a vDisk over iSCSI can be done from the GUI. There are 2 additional components which need to be installed:

The iSCSI Plugin

Install the iSCSI plugin on every host were the Framework is running.

´´´apt-get install openvstorage-iscsi-plugin´´´

Under Administration a new entry ´iSCSI Nodes´ will become available.

The iSCSI Manager

On every server where you want to expose iSCSI disks, install the iSCSI Manager package. The iSCSI Manager can installed independent of the Open vStorage Framework and Storage Routers as it connects by means of the Edge to the vDisk.

´´´apt-get install iscsi-manager´´´

After installing the iSCSO Manager, execute the setup.

´´´iscsi-manager setup´´´

Go through the setup steps:

Register the iSCSI nodes

Open the GUI and navigate to Admnistration > iSCSI Nodes and click the add iSCSI nodes button next to each server to register the nodes.

Expose a vDisk

To expose a vDisk over iSCSI, navigate to the vDisk detail page and click the expose button under iSCSI Actions. Select the iSCSI Node on which to expose the vDisk pass the edge username and password. Optionally an ACL can be supplied to indicate which IPs or networks are allowed to have access to the iSCSI disk.

Open Source Edition

In the Open Source Edition a vDisk can be exposed over iSCSI using the CLI. Note that the GUI integration is part of the Open vStorage EE version.

Install TGT and the Open vStorage TGT package. ´´´ echo "deb http://apt.openvstorage.com unstable main" > /etc/apt/sources.list.d/ovsaptrepo.list apt-get update apt-get install -y tgt tgt-openvstorage ´´´

Create a new target device.

´´´tgtadm --lld iscsi --mode target --op new --tid=1 --targetname iqn.2016-01.com.openvstorage:for.all´´´

Add a logical unit (LUN) ´´´tgtadm --lld iscsi --op new --bstype openvstorage+tcp --mode logicalunit --tid 1 --lun 1 -b 10.100.188.31:26203/volumeName´´´

Replace 10.100.188.31 by the IP of the Storage Router on which the vPool is exposed containing the vDisk. Replace 26203 by the edge port of the vPool on that Storage Router (see Storage Router detail page). Replace volumeName by the name of the vDisk you want to expose. Note that the vDisk should already be created.

Execute ´tgt-admin -s´ to see if the vDisk is exposed. The result should be something like

´´´root@PHY-3N-188-31:~# tgt-admin -s Target 1: iqn.2016-01.com.openvstorage:for.all System information: Driver: iscsi State: ready I_T nexus information: LUN information: LUN: 0 Type: controller SCSI ID: IET 00010000 SCSI SN: beaf10 Size: 0 MB, Block size: 1 Online: Yes Removable media: No Prevent removal: No Readonly: No SWP: No Thin-provisioning: No Backing store type: null Backing store path: None Backing store flags: LUN: 1 Type: disk SCSI ID: IET 00010001 SCSI SN: beaf11 Size: 10737 MB, Block size: 512 Online: Yes Removable media: No Prevent removal: No Readonly: No SWP: No Thin-provisioning: Yes Backing store type: openvstorage+tcp Backing store path: 10.100.188.31:26203/volumeName Backing store flags: ´´´
