I am looking to upgrade HMC's (7063-CR2) from V10 R1 M1011 to V10 R2 M1030. As per readme the recommended level VIOS to take advantage of all the functionalities of version V10 R2 M1030 is 3.1.3.x and later, however I have few VIOS in my environment which are either running on 18.104.22.168 or 22.214.171.124 level and could not be upgraded for few more months.
Even though there is no direct correlation between HMC and VIOS, however just want to make sure, if it would be fine to upgrade the HMC's without upgrading the VIOS?
It should be fine to update the HMC to 1030 level. HMC should be still be able to manage older version of VIOSs. Thanks!
I hope you saw the picture:
Yes You can proceed to upgrade the HMC's, it wont affect Your VIOSes but its always a best practice to update/upgrade all PowerVM related component for security improvements, Reliability and availability of the System, performance fixes and for any additional new functionalities that may have been introduced.
