How to create a missing Recovery Partition in Monterey

So a while back I had a problem with the internal Hybrid drive on my iMac Retina 5K, 27-inch, 2019. Took it in for support and all they could do was reformat the hard drive and I later recovered everything from my Time Machine backup.

Today I was trying to repair an external drive and went to boot into the recovery volume but it appears to be gone/not there. I am guessing that it did not get created when support reformatted my hard drive.

This drive is fairly full, 3 TB worth, so I am trying to recreate the Recovery partition without erasing the drive and and reinstalling the OS (Monterey) and then restoring the Time Machine backup.

Anyone have any ideas?

Thanks

iMac Line (2012 and Later)

How do you know it is not there? It isn't actually a partition in Big Sur and later. It won't be seen in the Startup Manager (Option key at startup).

Copy this command and paste into Terminal (hit return).

diskutil ap list

One of the many Volumes should be one with Recovery set as the Role.

+-> Volume disk1s3 C3D8AA0F-5CA2-4004-94C6-097ADA5B74E0
    |   ---------------------------------------------------
    |   APFS Volume Disk (Role):   disk1s3 (Recovery)

It will also show the mount point in /System/Volumes/

Update. Booted into Recovery Partition fine with Command R. Thanks for the help and advice.

That really helps. I guess it does show up under my fusion drive but no longer shows as a volume if I try to boot with the option key held down. I will try booting with command R to see if it will go into the drive as the recovery drive.

Thanks so much. I knew there was some command line wizardry that could at least identify it. If I have further issue I will be back to post.
