The Grep Command

-
Grep is used as search command

Example :

grep "emaad" filename.txt
grep ifconfig enpo164464245 | grep "inet"

 Grep "West" *
Will search West in all the files in current directory


man grep        ------------------ to pull up the manual page
q - to go back from manual screen


Grep "West" * -R  -> this will search recursively from in all the directories


Redirection with Grep : 

 Grep -i "west" * > File1.txt


-i is for case insensitive
Result will be stored in File1,txt

 Sort Command: 

Grep -i "west" emaad.txt | sort -k 2  (Colums 2)



Grep -i "^north" emaad.txt  ----------return lines begin with north
Grep -i "north$" emaad.txt  ----------return lines ends with north

SNMP Configuration on Brocade Switches

SNMP Manager   The SNMP Manager communicates to the devices within a network using the SNMP protocol. Typically, SNMP Managers manage networks by monitoring the network parameters and optionally setting parameters in managed devices.  SNMP Agent   The SNMP agent resides in the managed devices in the network and collects data from these devices. The SNMP Agent stores the data and sends these when polled by an SNMP Manager. The agent can also automatically alert the SNMP Manager about events by using specially configured triggers called traps.  Management Information Base   SNMP Agents in the managed devices store the data about those devices in a database called a Management Information Base (MIB).  The MIB lets the SNMP manager know what each value the device returns means. The MIB structure determines the scope of management access allowed by a device.   Basic SNMP operation Every Brocade device carries an agent and management informati...

Netapp Clustered Ontap CLI Pocket Guide On this page I will be constantly adding Netapp Clustered Data Ontap CLI commands as an easy reference Pocket Guide Most  Clustered Ontap  commands work in 8.x, however some require 9.x (I have created a note if they require a 9.x version) (Updated 04-Oct-2018) MISC set -privilege advanced (Enter into privilege mode) set -privilege diagnostic (Enter into diagnostic mode) set -privilege admin (Enter into admin mode) system timeout modify 30 (Sets system timeout to 30 minutes) system node run – node local sysconfig -a (Run sysconfig on the local node) The symbol ! means other than in clustered ontap i.e. storage aggregate show -state !online (show all aggregates that are not online) node run -node <node_name> -command sysstat -c 10 -x 3 (Running the sysstat performance tool with cluster mode) system node image show (Show the running Data Ontap versio...

Netapp 7-Mode Architecture

Image
7-Mode is made up of two controllers that is also called HA Pair (High availability Pairs) Controller : Controller (also referred to as Node) is the brain of Storage System where Operating System (Data ONTAP  Resides) and which deals with Read and Write operations. And it also contain memory, CPU. Disk Shelve: Disk Shelves are connected to the Controller in Daisy-Chained format, Disk shelve contain the actual physical disk on which your data resides. HA cable : The cable which connected two controller is called HA cable which is used for sending Keep alive signal between controllers which is used for Fail-over purpose that we will discussed later. 7 Mode Scalability Limitations: ·          You can have maximum 2 FAS Controllers ·          Disks owned by controller 1 can be accessed by controller 1 only ·          Data can be moved amon...
