Hi all,
We are planning to upgrade our cisco catalyst switch firmware but we are not sure if we have to shut down our 2 DL380 servers, MSA 2050 and HPE SN3000B san switch before the upgrade activity. Can anyone advice me on this. Thanks
Solved! Go to Solution.

Re: Does network switch firmware upgrade requires server, MSA and SAN switch shutdown?
Hello,
I didn't find any written doccumentation on this but in my opinion, I don't think it is required to shut down server, MSA and SAN switch while upgrading network switch firmware. Here are few pre-requisites that I found from 3rd party source(https://sjohnonline.blogspot.com/2019/05/network-switch-firmware-upgrade-best.html)
1) Check the current firmware version on primary and secondary flash.
Ex : 5406-CORE Chassis: 5406zl J8697A!
Serial Number: XXXXXXX
Primary Image: 14151077 03/08/11 K.15.04.0003
Secondary Image: 9782454 07/07/09 K.14.34
Current ROM version: K.15.12
Switch Modules: J9309A, J8702A, J9308A, J9308A, J9309A
2) Verify core switch architecture (Standalone or VRRP/HSRP/VSF)
3) Check for firmware upgrade path (If firmware is too old get help from vendor to get a correct upgrade path)
4) If firmware is too old vendors recommend for staged upgrade.
5) Select the firmware upgrade path, read the release notes carefully and ensure that all firmware versions in the path are compatible with the Hardware, Rom version, Modules (including management module) and commands of the Switch.
6) Release notes of respective firmware versions can be downloaded from the vendor’s website.
7) Download the required firmware versions from vendor’s website.
9) Ensure that the availability of uninterrupted power supply to avoid damage to your equipment, during the software update.
10) Take a valid recent running and start-up configuration backup of switch before the upgrade.
11) If the switch have 2 flashes, primary flash and configuration should be copied to secondary flash before the upgrade, So in case of any issues, switch can be boot from secondary flash, which is having current version of the firmware and configuration.

Hi Anu
Thanks for your feedback on this. Im thinking the same where we can see this as a network outage with no impact to server and MSA. The connection between server and MSA will be working fine since the connection from SAN switch is not affected.

SolutionHi,
MSA 2050 is managed through management controller IPs for controller A/B.
Even if management port communication link is down MSA host port links would still serve IOs.
I believe that all the host ports on MSA 2050 is using Fibre channel connection.
MSA 2050 supports both FC and iscsi connectivity to host servers when appropriate SFPs are used.
If the host port connectivity is FC , ethernet switch firmware upgrade should not impact MSA.
