A client is planning to move from VIOS 126.96.36.199 to VIOS 188.8.131.52 and the current HMC is 7042-CR9 and HMC version is V9 R1 M910 which is out of support and the latest HMC version supported on V9 R1 M910 is V9 R2 M953 which is also out of support. I want to check if there is any dependency of HMC on VIOS. Can we plan to upgrade the VIOS with the current HMC version?
Thanks in advance.
As such we do not have any dependency . You can independently upgrade your vios from the vios itself using viosupgrade in 2 steps .
First update from Vios 184.108.40.206 to 220.127.116.11 to get access to viosupgrade tool on vios cli
Update current VIOS Version from 2.x to 18.104.22.168 for non-SSP environment https://www.ibm.com/support/pages/node/6447005
Then upgrade the vios from 22.214.171.124 to 126.96.36.199 using viosupgrade
How to upgrade to VIOS Version 188.8.131.52 with IBM Storage and non-Shared Storage Pool Environment https://www.ibm.com/support/pages/node/6569541
Make sure your hardware supports Vios 3.1.4.x
System to VIOS maps https://www-01.ibm.com/support/docview.wss?uid=ssm1platformvios If you dont use IBM storage and have some 3rd Party storage used on VIOS . Please raise a case with IBM
Just a note during above process , you need to use HMC for some reason and you have a issue , for that you will have to work with HMC
Thanks for sharing the detailed information Deepak.
As per the readme file, Following would be update path:
184.108.40.206 --> 220.127.116.11 --> 18.104.22.168 --> 3.1.0.00 --> 22.214.171.124
