### Web Access GUI

Open following in web browser:

 

https://192.168.1.110:446/

 

username: openfiler

password: password

 

#### Creating bonded interface from 4 ethernet interfaces:

### Why? If any Interface is down, other interfaces will keep the network service up

 

System > Click on Create bonded interface

 

And follow steps as below:

Bonded-1

Bonded-2

Bonded-3

bond0     Link encap:Ethernet HWaddr

inet addr:192.168.1.201 Bcast:192.168.1.255 Mask:255.255.255.0

Volume Management – Software RAID

==============================================

 

Volumes > Block Devices

sw-raid-1

Click on /dev/sda

sw-raid-2

### Image below depicts 3 partitions we have made during Openfiler setup, besides we have 61% of free disk space i.e. 4.89GB

sw-raid-3

### Important note: Openfiler 2.99 has a bug that it does not continue from exact Starting cylinder, we must atleast choose 20 cylinders more

### Select default as above but change Starting cylinder to 20+ i.e. 426 and press Create to create an Extended partition.

### /dev/sda4 Extended partition (0x5) is created and enabling now for Mode: Logical in the end.

sw-raid-4

### Create 3 Logical RAID array members as following:

###Note: We have to use 1 more Starting cylinder due to Openfiler bug mentioned earler

 

RAID member 1:

sw-raid-5

RAID member 2:

sw-raid-6

RAID member 3:

sw-raid-7

Final Disk Layout:

### Note: All RAID Partitions should be of same size.

sw-raid-8

Click on Software Raid under Volumes section:

sw-raid-9

### Read carefully about RAID configuration to know what you want and what you are doing.
### Select RAID-5 (parity) Click on all 3 available devices (/dev/sda5-7) and click on Add array

### /dev/md0 RAID Array is created as below, click on View members and you will see the members window

sw-raid-10

Click on Add Volumes under Volumes section:

sw-raid-11

Type in Volume group name (no spaces) as above (e.g. ardata), tick the check box and click on Add volume group.

sw-raid-12

Volume Group ardata with 1.44GB size is created as above.

 

Click on Manage Volumes under Volumes section, to verify volume group ardata.

sw-raid-13

Click on Add Volume under Volumes section, to add iSCSI disk.

Fill in the fields Volume Name, etc and move slider to the end, to use all space, select block in Filesystem/Volume type. Click on Create

sw-raid-14

Volume is created:

sw-raid-15

Click on iSCSI Targets under Volumes section:

sw-raid-16

### If you find Target IQN disabled/Greyed out then you must start the iSCSI service:

You can see that iSCSI Target is Disabled and Stopped

sw-raid-17

Click on Enable and Start.

sw-raid-18

Click on Volumes main menu, and Click on iSCSI Targets under Volumes section:

sw-raid-19

Edit Target IQN e.g. iqn.2014-08.com.san2:openfiler.iscsisan4san2 but follow the defined pattern and click on Add button.

 

Press Update button with defaults:

sw-raid-20

Click on LUN (Logical Unit Number) Mapping:

sw-raid-21

And click on Map button

sw-raid-22

On another Linux machine run the following commands to access iSCSI:

 

[root@localhost ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.201

 

192.168.1.201:3260,1 iqn.2014-08.com.san2:openfiler.iscsisan4san2

 

[root@localhost ~]# /etc/init.d/iscsi restart

Back In web browser GUI, Click on Status main menu, under Status section click on iSCSI Targets:

sw-raid-23

 

You can see that iSCSI Target is being accessed by which client, click on View and you will find the IP address of Machine which is accessing the iSCSI Target. Click on Close Window to return on Main menu.

 

To have proper machine name in Initiator Name, edit the following file as:

 

[root@localhost ~]# vi /etc/iscsi/initiatorname.iscsi

Change from:

InitiatorName=iqn.1994-05.com.redhat:f58a244c8ec

 

To:

 

InitiatorName=iqn.2014-06.com.CentOS5-RAW:server-blank

 

Save & exit.

 

[root@localhost ~]# /etc/init.d/iscsi restart

Back In web browser GUI, Click on Status main menu, under Status section click on iSCSI Targets:

sw-raid-24

 

You can see the Initiator Name is changed as we changed earlier with same IP address.

 

On Linux machine by running fdisk -l will show that iSCSI disk (/dev/sdc) is available:

=================================================

Mounting iSCSI storage in Linux machine

=================================================

 

[root@localhost ~]# mkdir -p /mnt/iscisan

 

[root@localhost ~]# mount /dev/sdc1 /mnt/iscisan/

 

[root@localhost ~]# ls /mnt/iscisan/

lost+found

 

[root@localhost ~]# mount

/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)

proc on /proc type proc (rw)

sysfs on /sys type sysfs (rw)

devpts on /dev/pts type devpts (rw,gid=5,mode=620)

/dev/sda1 on /boot type ext3 (rw)

tmpfs on /dev/shm type tmpfs (rw)

none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)

/dev/sdc1 on /mnt/iscisan type ext3 (rw)

 

### You can see above Bold text which is mounted on /mnt/iscsisan.

### For further availability check run df -hT command:

[root@localhost ~]# df -hT

Filesystem   Type   Size Used Avail Use% Mounted on

/dev/mapper/VolGroup00-LogVol00

ext3   6.7G 2.2G 4.3G 34% /

/dev/sdc1     ext3   1.5G   35M 1.4G   3% /mnt/iscisan

 

### You can see above Bold text which is mounted on /mnt/iscsisan.

 

### From following netstat command you will know that which port iSCSI target is attached:

 

[root@localhost ~]# netstat -antp | grep iscsi

tcp       0     0 192.168.1.29:58479         192.168.1.201:3260         ESTABLISHED 4109/iscsid

 

=================================================

To permanently access iSCSI storage in Linux machine

=================================================

 

[root@localhost ~]# vi /etc/fstab

 

### Add the Bold as following to automatically mount iSCSI SAN on /mnt/iscsisan folder.

### Change defaults to _netdev, because if anytime at Linux machine reboot iSCSI san is not found / unavailable it will not halt/pause booting process.

 

/dev/VolGroup00/LogVol00 /                       ext3   defaults       1 1

LABEL=/boot             /boot                   ext3   defaults       1 2

tmpfs                   /dev/shm               tmpfs   defaults       0 0

devpts                 /dev/pts               devpts gid=5,mode=620 0 0

sysfs                   /sys                   sysfs   defaults       0 0

proc                   /proc                   proc   defaults       0 0

/dev/VolGroup00/LogVol01 swap                   swap   defaults       0 0

/dev/sdc1               /mnt/iscsisan           ext3   _netdev         0 0

 

### To check fstab is correctly modified, reboot Linux machine

 

[root@localhost ~]# reboot

sw-raid-25

### You can check in boot process that iscsid (iSCSI daemon) has initialized iSCSI targets and it has logged in and mount successfully.

 

### Check further from Terminal window by running following commands:

Physical Volume and Volume Group in Openfiler

=================================================

We are going to use remaining space on /dev/sda block device to create Physical Volume.

Click on Block Devices under Volumes section and click on /dev/sda:

sw-raid-2

### Type next number (e.g. 727) in Starting cylinder to the last RAID volume partition (e.g. 726):

sw-raid-26

### You can see below /dev/sda8 Linux Physical Volume (0x8e) is created with 1.97GB size.

sw-raid-27

### Click on Volume Groups under Volumes section, tick the check box to select, type in volume group name (e.g. vgsan) and click on Add volume group.

sw-raid-28

### You can see that ardata (iscsi) is already there in volume group.

sw-raid-29

### vgsan is created with 1.97GB size

 

### Click on Manage Volumes under Volumes section, select vgsan and click on change to verify volume group.

sw-raid-30

### Click on Add Volumes under Volumes section, type in Volume Name, etc and Create:

sw-raid-31

### Note: If you want to create multiple partitions, you can create here.

sw-raid-32

### lvsan Volume is created with 2016MB size
