The LSI Controller will fail because of the following migration issue: Migration from EXTS4 to XFS.
The Areca Controller will fail because of the following migration issue: Migration from EXTS4 to XFS
The HighPoint RocketRaid controller will fail because of the following migration issue: Migration from EXTS4 to XFS
During the Red Hat Enterprise Linux (RHEL) 7.0 - 7.6 run; 10 year time span. Most administrators used the top three raid cards in the EXTS4 configuration. Thus when the migration occurs to RHEL 8.0 most JBODS and RAID arrays will fail because they are on raid cards that have not been updated for the current software
See the following:
LSI Logic SAS3801E Dual SFF-8088 SAS/SATA: supports red hat 3
Please ask if your client/customer has an outdated raid card before migration to Red Hat Enterprise Linux 8.0
- Chris Donnelly
Idu, Yaju, could you look at it? Is it possible to detect use of outdated card reliably in automated way, so we would inhibit the upgrade to RHEL 8 in such cases? In case it is possible, who is the best person that would work on that?
Just to be clear, detection & inhibit doesn't have to be the solution of the problem - that was just my tip. If it is possible to resolve the issue in way users will be able to upgrade without this problem, it would be better solution :) Anyway, the decision what will be solution for this problem depends on someone else.

we can detect LSI Controller that on ESXi, just use the lspci command can filter the LSI Logic scsi controller. I am not clearly about how raid disk fails after upgrade to RHEL 8.0,
do you mean install RHEL 7.6 guest with EXT4 filesystem RAID disk, after upgrade to RHEL 8.0, the RAID disk would be failed?
I cc one of our developer Cathy, maybe she can give good suggestion for it.
@Cathy, could you help take look it?
Thanks very much!
We are going to need more information as to how this fails ( journalctl ) and lsmod and lspci output. Plus I don't understand how this migration process works. Please explain how migration or conversion from ext4 to xfs is done. This is done after the upgrade to rhel8? Please lay out the steps.
we are not doing any conversion from EXT4 to XFS during the upgrade process (as this is clearly even not possible in reliable way, right?). We do not even work with RAID storage. That's why I asked for person who is SSE for RAID (or storage let's say) and will work on that. To get the required info, I think that Chris is right person.
We can schedule a mtg to sync about the upgrades where we can explain you how upgrade works if you are not familiar with IPU 7 -> 8 yet.

I am trying to understand the process that you are performing. The BZ mentions upgrade to RHEL 8 and/or "Migration from EXTS4 to XFS". The BZ says there is a failure. I am asking for a little more clarity as to what is going on at the time of the failure, the logs, lsmod and lspci output. If Chris can provide that information great.
