HyperScale 1.5 Reference Architecture Upgrade

Question

Hi All,We are running the HyperScale 1.5 Reference Architecture with RHEL on top of HP Apollo 4200 Gen9 servers. Now we planning to upgrade the OS to 7.9 through CV FR upgrade. I have few quries and would like to hear from people who did the upgrade already.  As per CV, the upgrade takes around 60-90 min. What would be expected duration per node in real world.	Is there any firmware pre-request required for this upgrade?	Does anyone reverted the change successfully ? If yes, how long it takes per node	Do we have any check point to validate the upgradation once completed for first node? instaed waiting till 6th Node upgrade.  Thanks in Advance Mani

Hi @ManikandnAs per CV, the upgrade takes around 60-90 min. What would be expected duration per node in real world.30-40 minsIs there any firmware pre-request required for this upgrade?NoDoes anyone reverted the change successfully ? If yes, how long it takes per nodeRevert hasn't been required for any upgrade. First a transaction check is run on the rpm's that will be upgraded. If we find any issues, we don't proceed with upgrade until it's fix. Once transaction check is done, there are very minimal chance of upgrade failing mid-way.Do we have any check point to validate the upgradation once completed for first node? instaed waiting till 6th Node upgrade.For overall status, check the log /var/log/commvault/Log_Files/cvupgradeos.log on the node.Detailed progress of yum update can be monitored in yum.log and yum.err.log available in <commvault_logs>/hsupgradedbg folder.

Hi @ManikandnNo, that’s ran before the node is upgraded.
