Rolling back a firmware upgrade?

Just curious: what does it take to do a downgrade ? Simply choosing a lower version Flare code possibly not, but I just wonder what needs to be done just in case....

i think the array needs to be re-imaged...even if you go into engineering mode, the code cant be reverted afik....dont remember if engineering mode can let you downgrade by "upgrading" to older code bundle though...

With regards to FLARE software;

For any upgrade (either between major revs such as R22 to R24, or within a major rev such as R24 patch .011 to R24 patch .017) it's possible to "revert" back to the prior code up until the point in time when the new code has been "committed". The intent of the revert capability is to allow a new code rev to be installed, run for a period of time to evaluate, and easily rolled back (reverted) if desired. Note that when moving beteen major releases (e.g. R22 to R24) the array will continue to run with its existing feature set, and new features within the new major release will become available when the code is committed (for example when moving from R22 to R24, the R24 code needs to be committed in order to utilize RAID 6).

Outside the context of revert-commit, it's possible to install "old" software as long as it is within the current major release. Thus for an array that is running R24 patch .017 it would be possible to install R24 patch .011 - however it would not be possible to install R22 "over" R24 (since R22 is an older major release).

It is possible to downgrade the flare to previous version after commit...

This can only done under supervision of engineering team L3.

We can reimage the SP with the help of Mif file location in image repositery.

There are package available.....
