Brocade SAN Switch Zoning

In this post I will explain how to do the zoning in Brocade SAN switch using command line.

Open Putty and login to the switch with admin privileges.

Zoning involves mainly below steps

1. Make sure devices need to be zoned are logged into the fabric

Once the device connected to the SAN switch and powered on, a unique ID will be assigned to it. Unique ID is called as FCID. We can check if the device connected is logged into the fabric or not by using the below command.
                              
                                 nodefind <WWPN_No>

 This will give you the details if the device is successfully logged into the switch.



If the device is connected to the SAN switch and powered off then WWPN wont be showing up in the Webtool or in CLI. However zoning can be done using CLI even if the device is not connected to the SAN switch (This is not the best practice). Once the device gets connected the communication will start between the zone members.

2. Creating Alias of the connected WWPN

 Alias will be created for the easy understanding and management. This is to give the easy naming convention for the WWPN. Alias will be created by using the below command.

                             alicreate "<Alias_Name>","<WWPN_Number>"

 For Example: alicreate "a_SERVER1_PROD_FAB11", "50:01:43:80:17:87:F7:A4"

3. Creating the Zone

 Zoning is the process in which a path is established between 2 connected devices so that the data transfer takes place between them securely.

For example consider a server and 3PAR array which are connected to the same SAN fabric. And LUNs need to be allocated from 3PAR array to that server. In this case we would create a zoning between server HBA and 3PAR array Front end ports.

4. Saving the Zoning configuration

 Once the zone is created we need to save the active zone configuration. In one switch there can be only one Active Zoning Configuration. Zone configuration can be saved by using the below command

                             cfgsave

 5. Enabling the Zoning configuration

 By running the cfgsave command the newly created zones will only get saved but won't be activated. This is done by running the below command

                              cfgenable <Active_Zone_Config>

Configuration of FTP using 3CDaemon

Image
In this post I will show you the procedure to create a FTP using 3CDaemon tool. In Storage FTP is useful in uploading the Configuration and supportsave logs of Brocade Switch, firmware upgrade activity etc. In case if you do not have FTP server you can install 3CDaemon (Filezilla) to a server and you can use it as FTP server. You can download the 3CDaemon software from the below link. http://www.firewall.cx/downloads/16-1-3cdaemon-server-a-client.html Extract the Zip file and install (Setup.exe). Typical installation procedure (Next -> Next -> Install) Click finish to complete the installation. Once the installation completes open the 3CDaemon software. You could see there are TFTP, FTP and Syslog options available in the tool. In this post we will concentrate only on configuring FTP site. Select FTP Server as shown below. Click on Configure FTP server and go to FTP Profiles tab. (No need to make any changes in General Configuration tab) Profi

Drive Replacement in HP 3PAR Storage Array

In this post I will explain the procedure to be followed for Failed Drive replacement in HPE 3PAR Storage array. Physically this activity will be taken care by trained 3PAR Field Engineer. However there are steps need to be followed before and after the drive replacement is explained here. Usually this will be done by the 3PAR support engineer if the 3PAR array is under support. Anyways there is no harm in getting to know about this stuffs he he. In HPE 3PAR there are 2 types of Drive cages (Drive Array Enclosure) depends on the model. 1. In 10000 and 20000 models in one Cage there will be 10 magazines and in one magazines there will be 4 drives. So in each cage there will be total of 40 drives. 2. Where as in case of 7000 and 8000 series there will be 24 drives in one cage (There is no magazine concept in mid range 3PAR arrays). If you have the Dial home configured for your 3PAR array an auto case will be created from 3PAR support end and they will contact regarding the f

HPE 3PAR Storage Array - Health Check

Image
This post explains the steps to perform basic health check on HPE 3PAR storage array. This will give you the overall status of the array for example Hardware failures, Host status, VV status, port etc. Lets start. Login to to 3PAR array and execute the command checkhealth. This gives you the overall health check as shown below. In this case you can see there are 4 errors/faults which need to be taken care. For a clear understanding on the errors/faults you can run checkhealth -detail instead of checkhealth. checkhealth -detail will show the details of the errors. Sample output is shown below. Now we will see how to fix the errors in this case. LDs not mapped to a volume - These LDs can be removed from the system but we need to confirm these are not being used by any LUNs. I will explain the procedure to remove these unused LDs in coming posts. License which have expired - You can ignore this as in this case Peer motion license was bought on trial basis. PD that a
