This document provides 3 methods for accessing a NetApp cluster mode storage system through the command line interface (CLI). Method 1 involves connecting a laptop directly to the storage system's serial port using PuTTY software and logging in with username "admin". Method 2 allows using telnet or RSH by first cloning the firewall policy and enabling those services, but they are insecure. Method 3, which is recommended, uses SSH to securely access the storage system by hostname or IP and log in as "admin". The document provides instructions for downloading PuTTY and checking which CLI services are enabled or disabled.

1. NetApp Cluster Mode 8.2 Administration-:(Hot to access the
NetApp storage through CLI (command) line)
You can access yourNetAppClustermode systemsbyusingthree methods.
Method-1
1) Go physicallyandconnectyourlaptopto the serial console port(LaptopandNetAppstorage IP
range shouldbe inthe same subnet)
2) You mustinstall puttysoftware inyourlaptopordesktoptoget accessit
Openthe puttyin yourlaptopand checkthe which com port isenabledinyourlaptopor desktop
(windowsmachine)
Type the command inthe run ->compmgmt.msc as below
In the computermanagementselectthe device manager,inthe rightpanel note downthe COMport (it
may be COM1, COM2 or COM3 etc)

2. Note downthe com port as above and openthe puttyand selectthe Serial optionandgive the correct
COMport (COM1 here) andpressenter.

3. You will getthe console accessandit will askyouthe username and password.
Username -admin
Password -give the adminpassword
Method-2
By usingthe telnetorRSH-:
TelnetandRSH are disabledinthe predefinedmanagementfirewall policy(mgmt).Toenable the
clusterto acceptTelnetor RSH requests,youmustcreate a new managementfirewall policythathas
TelnetorRSH enabledandthenassociate the new policywiththe clustermanagementLIF.
Data ONTAPpreventsyoufromchangingpredefinedfirewallpolicies.However,youcancreate a
newpolicybycloningthe predefinedmgmtmanagementfirewallpolicyandthenenablingTelnetor
RSH underthe newpolicy.

4. Steps
1. Use the systemservicesfirewallpolicyclonecommandtocreate a new management
firewall policybasedonthe mgmtmanagementfirewall policy.
Example
cluster1::> system servicesfirewall policyclone -policymgmt -new-policy-name mgmt1
2. Use the systemservicesfirewallpolicycreate commandtoenable TelnetorRSHin
the newmanagementfirewall policy.
Example
cluster1::> system servicesfirewall policycreate -policymgmt1 -service telnet-actionallow-ip-list
0.0.0.0/0
cluster1::> system servicesfirewall policycreate -policymgmt1 -service rsh-action allow -ip-list
0.0.0.0/0
3. Use the networkinterface modifycommandtoassociate the new policywiththe cluster management
LIF.
Example
cluster1::> network interface modify -vservercluster1 -lifcluster_mgmt-firewall-policymgmt1
In the windowsmachine openthe puttyandselectthe protocol astelnetandenterthe IPorhostname
and accessthe NetAppstorage incli
It isnot secure protocol thatso whyplease don’tuse thisaswell asRSH

5. #rsh hostname_or_IP -l username:password
In the puttyselectthe Rloginoption
Note- If yourhost machine isLinux thenyoucan execute the commandinthe CLI,puttyisnot required
but if youare usingthe windowsmachine youneedputtysoftware toaccessthe NetAppclusterin
commandline (CLI)
You can downloadthe puttysoftware byusingthe below link.

Choose asper your32 bitor 64 bit OSyou are using.

6. Metheod-3
The most recommendedwaytoaccessthe NetAppstorage byusingthe commandmode isSSH (Secure
Shell)
Type the IP or hostname of the NetApp storage byselectingthe SSHprotocol asbelow

7. It will askyouthe username andpassword
User name- admin
Password -Administratorpassword
(Or)
loginas: admin

To see the webservice whichare enable ordisable youcanexecute the below command-:
cluster1::> system serviceswebshow
External WebServices:true

HTTP Protocol Port: 80
HTTPs Protocol Port:443
TLSv1 Enabled:true
SSLv3 Enabled:true
SSLv2 Enabled:false
Note- Please enable sshprotocol onlyasitisveryverysecure anddisable RSHand telnetservices.
