This is a short manual using screenshots to show how to configure Openfiler, mainly as

iSCSI target. I regularly use Openfiler as storage to test cluster setups with Oracle RAC

or other cluster software.

Openfiler is one of the options to have a storage with many interfaces: NFS, SMB, rsync,

 WebDAV, FTP, iSCSI and more:

SETUP OPENFILER AS VIRTUAL MACHINE 

Download an ISO image here, setup a new virtual machine and add i.e. one hard disk for

Openfiler itself and two more for shareable storage.

I won’t cover setting up Openfiler in detail here as the installation itself is easy.Resources for this are:

RAC(german).

LOGGING IN INTO OPENFILER WEB ADMINISTRATION  

Navigate to https://192.168.3.66:446/  and login using openfiler as username, password as

password. You will see a status page:

CONFIGURE BLOCK DEVICES 

 Add the two other hard disks as block devices to Openfiler. Click onVolumes (upper

menu) ->Block Devices (right menu).

SETUP A VOLUME GROUP  

To add a volume group which consists od physical volumes, go to Volumes -> Volume Groups:

SETUP SOME VOLUMES 

Click on Volumes -> Add Volume and give the volume a name, size and filesystem type:

 After adding some volumes, Volumes -> Manage Volumes looks like this:

SHARE VOLUMES 

Now share volumes by adding a iSCSI target, Volumes -> iSCSI Targets -> Target

Configuration:

Click on “Add” under “Add new iSCSI Target”. 

Next, click on LUN Mapping and assign a LUN to your volumes. Just click onMap in the list

of unmapped volumes. After that the page “LUN Mapping” should look like:

ENABLE SERVICES 

To use iSCSI you need to enable it under Services. Just click on the Enable link of all

services you need:

SETUP ACCESS CONTROL 

Under System add the desired hosts and/or networks that are allow to connect to

Openfiler:

Next be sure to allow access in Volumes -> iSCSI Targets -> Network ACL:

Set Access to Allow and click Update.

 Attention: maybe you won’t see iSCSI targets from the client. Openfiler won’t accept

connections; check /etc/initiators.deny  for an entry denying access from ALL. Just

comment it out and save the file. Take care: Openfiler will regenerate this file from time

to time… 

 ACCESS ISCSI TARGETS FROM SOLARIS 

Enable iSCSI initiator service:

1.  root@rac1:/ # svcs *iscsi* 2.  root@rac1:/ # svcadm enable initiator 

Enable send target mode with iscsiadm modify discovery:

1.  root@rac1:/ # iscsiadm modify discovery --sendtargets enable 2.  root@rac1:/ # iscsiadm list discovery 3.  Discovery: 4.  Static: disabled 

5.  Send  Targets: enabled 

6.  iSNS: disabled 

 Add the IP address of your iSCSI target with iscsiadm add discovery-address:

1.  root@rac1:/ # iscsiadm add discovery-address 192.168.3.66 2.  root@rac1:/ # iscsiadm list discovery-address 3.  Discovery  Address: 192.168.3.66:3260 4.  root@rac1:/ # iscsiadm list target 5.  Target: iqn.2006-01.com.openfiler:tsn.bb9e3f57be77 6.   Alias: - 

7.  TPGT: 1 

8.  ISID: 4000002a0000 

9.  Connections: 1 

Create device files using devfsadm so that Solaris can start using the new disks:

8/14/2019 Openfiler-how to configure.docx

http://slidepdf.com/reader/full/openfiler-how-to-configuredocx 12/12

1.  root@rac1:/ # devfsadm -C -i iscsi 

Repeat this after you changed iSCSI targets by removing or adding LUNs. You can see a

list of the devices using iostat -En:

1.  root@rac1:/ # iostat -En 2.  c0d0 Soft Errors: 0 Hard  Errors: 0 Transport Errors: 0

Now fdisk, format and newfs the devices. See Formatting Many Raw Devices At Once on

Solarisf or a script to format many raw devices at once.

Have fun!
