Objective

This article describes how to rescan QLogic Host Bus Adapter (HBA) for new Logical Unit Numbers (LUNs), and query the HBA or ISCSI in XenServer 6 and later.

Requirements

XenServer 6 or later
Basic Command Line Interface skills

Instructions

Repeat the following steps on each server in the pool:

Run the following command to find the scsi_host directory. To be able to send the command for rescan you must find the correct scsi_host directory:
# cat /proc/scsi/scsi
You can see that that the HBA driver is mapped to host scsi3 and scsi2, which XenServer translates to host2 and host3.
Note: Servers in the pool might be having different scsi_host numbers.
Run the following command to view the current LUN count:
Note: If 'scli' is not in the path, you can find it at /opt/QLogic_Corporation/QConvergeConsoleCLI/scli
Send the rescan command and check the LUN count update:
# echo '- - -' > /sys/class/scsi_host/host2/scan
# scli –t
# echo “- - -“ > /sys/class/scsi_host/host3/scan
# scli –t
Run the following command to view the LUN details:
# scli –l 0
# scli –l 1
Run the corresponding commands from the following list, to display HBA and SCSI details using systool:
- To examine some simple information about the Fibre Channel HBAs in a unit:
  # systool -c fc_host –v
- To look at verbose information regarding the SCSI adapters present on a system:
  # systool -c scsi_host –v
- To see what Fibre Channel devices are connected to the Fibre Channel HBA cards:
  # systool -c fc_remote_ports -v –d
- For Fibre Channel transport information:
  # systool -c fc_transport –v
- For information on SCSI disks connected to a system:
  # systool -c scsi_disk –v
- To examine more disk information including which hosts are connected to which disks:
  # systool -b scsi –v
- Use the sg_map command to view more information about the SCSI map:
  # sg_map –x
- To obtain driver information, including version numbers and active parameters:
  For QLogic HBAs:
  # systool -m qla2xxx –v
  For Emulex HBAs:
  # systool -m lpfc –v

Hi all, here is my new Mini-Howto for Citrix XenServer – Storage Repository Over Software iSCSI LUN

Topic contains:
How to Create NFS and iSCSI LUN on Linux (I will CentOS)
How to mount them on Citrix Xen Server using Command line and GUI (that includes Screen Shots)

Let’s starts with iSCSI creation on linux box, I will use CentOS 6 for this.

Packages Required: scsi-target-utils

Configuration File: /etc/tgt/targets.conf

I will Use LVM, as i am using a large partition on this box. So proceeding with it:

Press ‘n’ for new partition

First Cylinder size: press enter

Note: do not format partition:

Now create Physical Volumes (PV) on newly created partition.

# pvscan

Now create Volume Group (VG) : on created PV

# vgscan

Now we can create one or more Logical Volumes (LV’s) on VG

# lvscan

This part is done: Now to LUN creation

For this we have to ensure we have required package:

iscsi-initiator-utils-6.2.0.872-34.el6.x86_64

scsi-target-utils-1.0.14-4.el6.x86_64 (this is main package required for iSCSI server)

If do not have, the install it either using directly from RPM if you have, or YUM

After the successful installation, we have to edit the config for SAN:

iqn.2012-08.web18:vmsan>

# Example: the next line would override default driver type.

backing-store /dev/ sr0_vg1/ name sr0_vg1_lv100

backing-store /dev/ sr0_vg1/ name sr0_vg1_lv102

Citrix Scsi Interface

#initiator-address 192.168.23.113 (by proving IP, we can restrict the storage to specific IPs only)

Now start the service of iSCSI target:

# chkconfig tgtd on

(this will display information about iscsi target device)

I have disabled IPTABLES on target server, in my case.

This is done, Now i will show you how to mount the available LUN on Citrix Xen Server using GUI.

Later I will add command prompt, currently I am facing some issue, suggest me if you have steps

Open XenCenter àRight Click on any XenServer aChoose New SR….

In Next window, choose Software iSCSI and click Next

Provide IP of Target server (iSCSI server) and click on Discover IQNs, choose your IQN and then click on Discover LUNs and choose your LUN that you had created during LVM create.

Click on Finish and the XenCenter automatically mounts it on Server

Now LUN is ready and mounted on XenServer, start using as your need.
