Steps to setup NetApp Cluster-mode

Step: 1 Hardware setup

a. Connect controllers to disk shelves (FC connectivity)
b. NVRAM interconnect to high availability cable between partners (10GbE or infiniBand)
c. Connect controllers to network such that each node have exactly two connections to the dedicated cluster network, at least one data connection. Also the well known RLM connection for troubleshooting purposes when needed.

Note: Cluster connections must be on a network with dedicated cluster traffic, where as data and management connections are on a distinct network.

Step:2 Power-up

a. Power up network switches
b. Power up disk shelves
c. Power up storage controllers

Step:3 Firmware

a. During boot process press any key to enter the firmware
b. Two compact flash images: flash0a and flash0b are available. To 'flash' (put) a new image on primary flash one needs to configure management interface.

Note: For auto option of ifconfig, DHCP or BOOTP server must be available on management network. If it doesn't one must run ifconfig <interface> addr=<ip> mask=<netmask> gw=<gateway>

c. Once the network is configured, ping to test and flash the image; run flash tftp://<tftp_server>/<path_to_image>flash0a

Step:4 Installing ONTAP 8.1

a. Run option 7 to install new software first
b. Enter a URL to ONTAP 8.1 tgz image
c. Allow the system to boot when complete

Note: One can type boot_primary if node stops at firmware prompt

Step:5 Initialize a Node

a. Run option 4
b. This initialization clears the three disks that the system uses for the first aggr that it creates and a vol0 root volume on it
c. This must be run on both nodes of each HA pair

Step:6 Cluster setup wizard

a. From boot menu, boot normally and login as "admin" with no password
b. The first node creates the cluster
c. The following information is required for the setup:
-Cluster name
-Cluster network ports and MTU size
-Cluster base license key
-Cluster management port, IP address, netmask, and default gateway
-Node management port, IP adress, netmask, and default gateway
-DNS domain name
-IP address of DNS server
d. Subsequent nodes join the cluster

Step:7 Normal boot sequence

a. Firmware loads the kernel from CF
b. Kernel mounts "/" root image from rootfs.img on CF
c. Init is loaded and startup scripts run
d. NVRAM kernel modules gets loaded
e. Tmgwd is started
f. D-blade, N-balde and other components are loaded
g. vol0 root volume is mounted from local D-blade
h. CLI and element manager are ready for use

Step:8 Create a cluster

cluster create -license <name> -clustername <clustername> -mgmt-port <port> -mgmt-ip <mgmtip> -mgmt-netmask <mgmtnetmask> -mgmt-gateway <magmtgateway> -ipaddr1 <clusterip1> -ipaddr2 <clusterip2> -netmask <clusternetmask> -mtu 9000

Step:9 Join a cluster

Run this command from the node that wants to join the cluster

cluster join -clusteripaddr <remoteclusterip> -ipaddr <clusterip1> -ipaddr2 <clusterip2> -netmask <clusternetmask> -mtu 9000

Step:10 Licenses

a. Base
b. NFS
d. iSCSI
e. FCP
f. SnapMirror_DP
g. SnapRestore
h. Flexclone

Note: One can add licenses in the cluster shell; system license add

Step:11 NTP

a. NTP is disabled by default and needs manual set up of date, time and time zone

system date modify

b. Verify and monitor
