Useful Celerra commands

Command:1 Create file system

/nas/bin/nas_fs -name fs1 -type uxfs -create size=<initial size> pool=<from pool> -auto_extend yes -max_size <max size> -vp yes -option slice=y,mover=server_2

Command:2 Create Mount Point

/nas/bin/server_mountpoint server_2 -create /fs1

Command:3 Mount File System

/nas/bin/server_mount server_2 fs1 /fs1

Command:4 Enable Unicode for CIFS Compatibility

/nas/sbin/uc_config -on -mover server_2

Setup iSCSI storage on Celerra

Step:1 Validate network interface on data mover

server_ifconfig server_2 -all

Step:2 Create and mount a file system called iSCSI

nas_fs -n iscsi -c size=100G pool=clar_r5_performance

server_mount server_2 iscsi /iscsi

Step:3 Create the celerra iSCSI target

Virtual Data Mover (VDM)

What is a VDM?
=============
-It is a feature that allows the separation of CIFS servers and their associated environment into virtual containers
-Enables replication of CIFS environments from a primary site to a secondary site without impacting server access
-Allows the movement of CIFS servers from one Data Mover to another
-VDMs store dynamic configuration data such as; local groups, shares, security credentials, audit logs, home dir information, kerberos

NetApp Cluster-mode networking deep dive!

While administering NetApp cluster-mode, it's very important to understand networking and related concepts for successful troubleshooting in case of network failures. In this post I will be discussing the key network concepts related to cluster-mode.

Networking has gained special focus in cluster-mode with a goal to integrate fully qualified, high-performance switches into the sacle-out cluster and management networl

Key concepts:
==========
-Each controller have multiple physical network ports depending upon the controller model
-Physical network ports and logical interfaces (LIFs) are two different entities
-SAN environments use HBA ports as data ports
