About FC SAN – Collection

After made some modification in our SAN network i need to describe all

First  about the design(Architectural) point of view very clear explanation from brocade. Actually my design is between mesh and core-edge

About the limitations need to read each FOS version scalability guidelines , this is for version 7.x  (FOS is Fabric OS , Firmware or Operating System of brocade switch) its important because how many switch(domain id) supported per fabric, how many access gateway per fabric, how many node per fabric, number of zone

if you dont know what is Domin, Domain ID, E Port, N Port pls read IBM Redbooks (Chapter 2 and for Domain ID page 405 Principal Switch Selection)

About Brocade Access Gateway read this (1.1.1 Basic Concept, 1.1.2 Port Mapping, 1.2 NPIV_ID Virtualization, 1.3 Benefits, 1.3.4 Cost Reduction , 1.5 Limitations)

Most important question mark in my mind was multiple connection between Brocade Access Gateway to Fabric SWITCH for availability , read section 2.4.1 in same document , i tested and F port to N port mapping are switched and communication is continue without any issue at the fail-over time

About Brocade Access Gateway port mapping use same document or fallow related link

For ag commend reference

For change FC switch to Access Gateway execute commands bellow

First you have to disable switch (this is also needed if you update the licenses on switch too)

Jango-Fett:admin> switchdisable

Disable auth policy

Jango-Fett:admin> authutil –policy -sw off    Warning: Activating the authentication policy requires either DH-CHAP secrets or PKI certificates depending on the protocol selected. Otherwise, ISLs will be segmented during next E-port bring-up. ARE YOU SURE  (yes, y, no, n): [no] y
Auth Policy is set to OFF

Use such commend if you want to sure that you really disabled

Jango-Fett:admin> authutil –show
AUTH TYPE     HASH TYPE     GROUP TYPE ————————————–
fcap,dhchap     sha1,md5     0,1,2,3,4 Switch Authentication Policy: OFF Device Authentication Policy: OFF
Then switch to access gateway mode, switch configs will be deleted and rebooted

Jango-Fett:admin> ag –modeenable
WARNING: Access Gateway mode changes the standard behavior of the switch. Please check Access Gateway Administrator’s Guide before proceeding. Enabling agmode will remove all the configuration data on the switch including zoning configuration, FAWWN configuration and security database. Please backup your configuration using configupload. This operation will reboot the switch.
Do you want to continue? (yes, y, no, n): [no] y
Access Gateway mode was enabled successfully Switch is being rebooted…

Additionally need to know about licensing  because from community i can see many question about ISL , people says ISL need license but actually ISL Trunking need optional license

Multiple ISL connection between two fiber switchs without ISL Trunk

Before i posted some different articles for connect multiple switch together, now i will show you the how multiple ISL connection you can do without ISL Trunk
Problem is from Brocade community pages i can not find out right answer or i don’t know answers why not enough helpful for such big company community page 😦

Short explanation , because of FC network is do not have any Ethernet based Spanning Tree kind of issue , you can do easily multiple connection between two switches. My purpose is not load balance or any port saturation , just only have an issue about my E port , for to do this i have to switch the E port or ISL port.

I plugged the second connection between two switches without any interruption and FC switches take care about routing and traffic like below. P0 and P2 are two E ports. This is Dynamic Load Sharing. You can see it with execute “dlsshow” command which show that dls set or not or you can set it with “dlsset” command to enable it. I guess its come default because our switches 1-4 years old and they have it.

A note for you , I’m not completely sure but when i unplug on of E port , i saw some short latency increase on storage site.

Also a good comments you have to take care about to see the topology and paths

Use “urouteshow” , “topologyshow”

Also when i search something finally i found perfect pdf file which everybody should read it

FC Brocades / IBM Branded Brocades / EMC Branded Brocades ISL Connection

i accept that you are adding new fc switch to fabric, this document do not related with merge something

Be sure no configuration on new switch, if it has then clear it

Savage_Opress:FID128:admin> cfgshow

Defined configuration:

no configuration defined

Effective configuration:

no configuration in effect

You do not have to deal with DomainID, default every switch have DomainID 1 and when you join the new switch to new existing fabric need to be restart because need to be election if without reboot you connect two fc switch via ISL link, you will get incompatible …

Savage_Opress:FID128:admin> islshow

1:  0->    (incompatible)

Try to reboot new switch you will see that it will join to new fabric like below (to reboot fc switch type “reboot” to go )

Savage_Opress:FID128:admin> islshow  1:  0->  4 10:00:00:05:33:55:ef:af   2 Chewbacca       sp:  8.000G bw:  8.000G

Chewbacca:admin> islshow
1: 0-> 3 10:00:00:05:1e:d6:5c:19 1 R2D2 sp: 8.000G bw: 8.000G
2: 4-> 0 10:00:00:05:33:ab:b9:95 3 Savage_Opress sp: 8.000G bw: 8.000G

Now this configuration is cascade base installation , Chewbacca connected to R2D2 , Savage connected to Chewbacca , if you want you can connect Savage to R2D2 for ring topology

Also maybe you have a question on your mind, domain name is not important on this configuration.

FC Brocades / IBM Branded Brocades / EMC Branded Brocades FOS Upgrade

Go …

Download related FOS and out it on any FTP server or you can use SCP too ! File Name section you can see that i indicated folder no any file just folder where all files inside. IBM redirect to special website of Brocade to download, on EMC powerlink you can download it too !

if you ask me what is the big issue of purchase branded fc switch , answer is very easy EMC say aaaa this is IBM branded ask they, IBM yes this is EMC one problem should be there 😀 very funny isn’t it because they are selling same product

Pls do not ask me something about firmwares because most hard thing is this

Savage_Opress:FID128:admin> firmwaredownload
Server Name or IP Address: xxx.yyy.ttt.zzz
User Name: iso

Checking system settings for firmwaredownload…
System settings check passed.

You can run firmwaredownloadstatus to get the status
of this command.

This command will cause a warm/non-disruptive boot but will
require that existing telnet, secure telnet or SSH sessions
be restarted.
Do you want to continue (Y/N) [Y]:
Firmware is being downloaded to the switch. This step may take up to 30 minutes.
Preparing for firmwaredownload…
Start to install packages…
dir ##################################################
ldconfig ##################################################
glibc ##################################################

You can see that linux running on it, lovely. Hey Windows lovers waiting someday fc switches run on Windows maybe on 2199 when its more powerful or more fit or whatever  🙂 .. Go …

All packages have been downloaded successfully.
Firmware has been downloaded to the secondary partition of the switch.
HA Rebooting …

Now, reconnect switch and execute

FC Brocades / IBM Branded Brocades / EMC Branded Brocades First Time Installation

quick as possible

Connect console cable (sorry i don’t like EZSetup) 9600,n,8,1 Flow is none

Default user is admin and password is password 🙂

Pls do not forget i don’t know which terminal you will use like  Putty / SecureCRT or bla bla don’t backspace something such terminals can understand different sometimes and you can not logon or something will be wrong

Brocade will ask you 4 users pass which are root,factory,admin,user

then, continue hope ip address are ready to go , pls type like below

ipaddrset

Darth_Maul:FID128:admin> ipaddrset
Ethernet IP Address [192.168.21.9]:
Ethernet Subnetmask [255.255.255.0]:
Gateway IP Address [192.168.21.1]:
DHCP [Off]:

Not: Type your one, i already did it

Connent GUI like http://ip.address.of.yourdevice

Click Switch Admin –> 

  • Change the name of switch
  • Set DNS Address
  • Set Domian Name
Apply it !

Click Licenses –>

it should be empty or just only default/embedded ones should be

Now my switch is IBM one and i need to go web site http://www-912.ibm.com/LicenseRequestClient/
Not: Other vendors should have their own one, ask to they 

On terminal type like below to get License ID

Darth_Maul:FID128:admin> licenseidshow
10:00:00:05:33:d2:81:1d

Type your email address and all transaction key step by step with license ID to get Activation keys

Back to GUI again , on license section and enter license keys , then grey sections of switch become more beautiful to you 😀

After add license execute such commands

Darth_Maul:FID128:admin> switchdisable
Darth_Maul:FID128:admin> switchenable

Now its beautiful ..
