Creating a Shared Virtual Disk for Live Migration

10.1.0.249:3260,1 iqn.1992-04.com.emc:cx.apm00070202838.a0 10.1.1.249:3260,2 iqn.1992-04.com.emc:cx.apm00070202838.a1 10.2.0.250:3260,3 iqn.1992-04.com.emc:cx.apm00070202838.b0

4.Delete entries that you do not want to use, for example:

iscsiadm -m node -p 10.2.0.250:3260,3 -T iqn.1992-04.com.emc:cx.apm00070202838.b0 -o delete iscsiadm -m node -p 10.1.0.249:3260,1 -T iqn.1992-04.com.emc:cx.apm00070202838.a0 -o delete iscsiadm -m node -p 10.2.1.250:3260,4 -T iqn.1992-04.com.emc:cx.apm00070202838.b1 -o delete iscsiadm -m node -p 10.1.1.249:3260,2 -T iqn.1992-04.com.emc:cx.apm00070202838.a1 -o delete iscsiadm -m node -p 10.0.1.249:3260,5 -T iqn.1992-04.com.emc:cx.apm00070202838.a2 -o delete

5.Verify that only the necessary entries are visible: iscsiadm -m node

6.Review the partitions by checking /proc/partitions:

cat /proc/partitions
major minor		#blocks	name
8	0	71687372	sda
8	1	104391	sda1
8	2	71577607	sda2
253	0	70516736	dm-0

2531 1048576 dm-1

7.Restart the iSCSI service: service iscsi restart

8.Review the partitions by checking /proc/partitions. A new device is listed.

cat /proc/partitions major minor #blocks name

80 71687372 sda

8	1	104391	sda1
8	2	71577607	sda2
253	0	70516736	dm-0
253	1	1048576	dm-1

816 1048576 sdb

9.The new device can now be used. fdisk -l /dev/sdb

10.Create a new directory named /etc/ocfs2 directory: mkdir /etc/ocfs2

11.Create the OCSF2 configuration file as /etc/ocfs2/cluster.conf. The following is a sample cluster.conf file:

node:

ip_port = 7777

ip_address = 10.1.1.1 number = 0

name = example1.com cluster = ocfs2
