Upgrading Palo Alto

 Upgrading Palo Alto is very easy in compared to any other next generation firewall. We just need to be careful with few of the things 

1. Downloading software

Go to Device > Software and we will need to check which software version are we trying to upgrade to.

Note : We cannot directly jump for one major version to another like from 9.1.x to 10.1.x. We will need to go from 9.1.x to 10.0.x. This is how it normally works in most of the firewall.



We now need to select the version we want to install it and directly download it to our software repository. As our PA 3220 is in HA we can also directly sync the downloaded software to our secondary PA 3220.



2. Installing Software
Once we download the software we can now install the software. The software upgradation process does take around 10-15 mins approximately. Palo Alto will reboot and gets started automatically.




3. Verification
Palo Alto has now rebooted and is upgraded as well.

SAN Switch Zoning with Brocade

Zoning in Brocade SAN Switch Let's begin with resetting the switch completely. In my environment I have two brocade SAN Switch connecting to 2 Dell R940 server configured with VMware. The SAN switch will be having connectivity between Dell Unity 500 storage and Dell R940 servers. Multipathing will be done between the server and storage with the help of SAN Switch. Multipathing, also called SAN multipathing or I/O multipathing, is the establishment of multiple physical routes between a server and the storage device that supports. It results in better fault tolerance and performance enhancement. DESIGN The idea behind zoning is that intended WWPN talk with each other . This is more like ACL in the world of Ethernet. To see the devices which are logged into the switch the following commands can be executed. SAN-A:admin> switchshow switchName: SAN-A switchType: 118.1 switchState: Online switchMode: Native switchRole: Principal switchDomain: 1 switchId: ...

Device Mapper Multipath with LVM in Oracle Linux

This blog describes you the step by step procedure for configuring multipath in liunx using Device Mapper and will also help you understanding what Device Mapper is. Simply stating Device Mapper is an interface to Linux Kernel which helps us to configure multiple I/O path between the server and the storage arrays.  Device Mapper interface allows the linux kernel to communicate with LVM Logical Volumes, EVMS Volumes , Software RAID, multipath and many other solutions. Multipathing is a must for all those mission critical applications as we all know that data is the most important thing in an enterprise network . Let me now share the installation process for multipathing. Installing Device Mapper #yum install device-mapper-multipath -y #rpm -qa | grep device-mapper Enabling Multipath #cp /usr/sare/doc/device-mapper-multipath - */multipath.conf   /etc/multipath.conf #mpathconf -enable -user_firendly_names n #modprobe dm_multipath #lsmod | grep dm_multip...

Upgrade Catalyst C9500

Upgrading Catalyst 9500 series switch is relatively easy. The one that I'm going to upgrade today is on Install mode containing packages.conf file. Install mode consumes far less resources in compared to the traditional bundle mode and has some advantage like auto upgrade when configured in stacked mode. We can talk about the difference between bundle and install mode later on. Let's focus on upgrading the Catalyst 9500 switch. Switch I am trying to upgrade is in 17.03.03 which has some bugs and security vulnerabilities. I am upgrading it from 17.03.03 to 17.6.5(MD) golden image present in the cisco download site for C9500 series switch and also reading down the linked document from cisco that is what they recommend. You can have a look at it . https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9300-series-switches/221498-recommended-releases-for-catalyst-9200-9.html We will first need to create FTP username and password in the switch. The username and password must b...
