INSTALLING THE NETAPP FILER SIMULATOR

INSTALLING THE NETAPP FILER SIMULATOR ON LINUX MACHINE (on the dns machine)

A] PHASE I : Installing the Netapp Filer Simulator Software

1. Copy the software (7.3.5-sim-cdrom-image-v22.iso) from local machine to the "DNS Server" using winscp

From the windows terminal server upload the file 7.3.5-sim-cdrom-image-v22.iso using winscp to your DNS server.

2. Mount the ISO image on the DNS Server

mkdir -p /virtual-cd

mount -t iso9660 -o loop /root/7.3.5-sim-cdrom-image-v22.iso /virtual-cd

3. Run the installer /virtual-cd/setup.sh and install the software under /netapp/sim1

Please enter the IP address for the Network Interface ns0 : 172.168.0.100

Please enter the netmask for the Network Interface ns0 : 255.255.0.0

Please enter media type : auto

Change the timezone, SMTP mail host to localhost and provide email address

------------First-time configuration ENDS HERE------------------

Go to the Web Admin Interface using browser to URL : 172.168.0.100/na_admin (For Web-based Administration)

C] PHASE III : Configuring Aggregates, Volumes and LUNs

Multiple Physical Disks connected to the SAN are grouped together in RAID-X Group

From the RAID-Group you allocate space for LUNs. These LUNs can now be accessed from the masked hosts.

Masking is a process of making a LUN visible to a particular host either by

a. using the WWN number of the HBA in case FC-SAN

b. using the IQN number of the iSCSI HBA in case of IP-SAN

c. using the IQN number of the iSCSI initiator software in case of IP-SAN but no HBAs installed on the host. (This is our model)

Aggregate : Is a collection of physical disks (we have 25 spare) with some "RAID" level

Volume : Is a separate disk space created inside an aggregate. Volumes can have its own "RAID" level

LUN : Logical Unit Number is a logical disk space presented to a given host and the host treats this as a hard disk.

LUNs are created inside a VOLUME.

Depending on the SAN implementation, a LUN could be FC-LUN and iSCSI-LUN

FC-SAN uses : Fibre Channel Protocol (FCP) - Real Life

FC-SAN =======> SAN-SWITCH =======> HOST (FC-HBA has WWN number)

IP-SAN uses : iSCSI Protocol (Lab Setup)

IP-SAN =======> NETWORK-SWITCH/FCoE Switch =======> HOST (NIC has MAC address)

NetApp Filer Simulator ===> Virtual Switch/Software Switch ===> Host-VM (vNIC has MAC address)

1. Create Aggregate

aggr create racaggr -t raid4 25

-- only 2 RAID levels are supported by the Simulator - RAID-4 and RAID-DP

2. Create a Volume

vol create oravol racaggr 17g

3. Create LUNs

lun setup

Your response :

Do you want to create LUN? y

Multiprotocol type of LUN : linux

Enter LUN path : /vol/oravol/lun0

Do you want to create a space reserved LUN : y

Enter the LUN size : 3g

Enter comment :

Enter the name of the initiator group : RACGRP

Type of initiator group : iSCSI

Enter comma separated node names : iqn.2017-01.com.demo:node1

iqn.2017-01.com.demo:node2

iqn.2017-01.com.demo:node3

<ENTER>

OS type for the initiator group RACGRP : linux

Create 4 LUNs of 3GB each. (run above command for 4 times)

4. Verify the luns : lun show (rw/online/mapped)

5. Start the iSCSI service and verify the status

iscsi status ===> Down/Not Running

iscsi start ===> Start the iSCSI service on the Netapp Filer Simulator

iscsi status ===> Up/Running.
