What does "force devmap reload" as in "multipath -r" means for my system and stability of my system?

Cannot present unpresented disks back again. On a test server tried this as a solution "multipath -r" and it worked. Too worried to try it in production before I know all the information.

Any info would be appreciated!

Also some links to the documentation on this specific issue could help a lot. Couldn't find it myself.

There are more that 42 disks in production, I want to add 5 more. They've been unpresented before.

Can you please provide your operating system version and revision number. Also, the hardware/storage you are using.
