Hi Everyone,
IHAC want to remove some disks form 3par 8400.
I have some steps as below, which can dismiss the PD. But I still have some quries. So Thanks a lot if anyone give me some advice...
movepdtospare -dr 59 #assume the PD to remove is 59, dry run the movepdtospare
movech -perm 59:0-11:765 59:1-4:769 59:3-3:768 #move the chunks from pd59 to another spare chunks
showpdch -from 59 #verify there is no connection in pd 59
removespare 59 #remove the spare chunks
dismisspd 59 #successfully dismiss the pd 59
Then moved chunks are still in the spare space. How can I move these chunks to normal space?

Re: Remove a PD permanently
> When we are running dismisspd 23 then we got error
Why do you want to remove the PD? The proper command is servicemag to replace them.
If you really really want to dismisspd, you need to follow all of the instructions in this topic by @giladzzz.

7 removespare PDID:a Removes the Spare chunklets from the PD
8 dismisspd <DiskID> Dismisses the PD from the 3PAR
But when we run dismissed pdid then we are getting error "pd I'd 23 is referenced by chunklet 1:221"

Again, why do you want to dismiss the PD?
You're going to have to provide the output from the commands you did.
But before you start, please provide this output:
showpdch -mov

Re: Remove a PD permanently
> showpdch -mov --Attached
Looks like none of the 337 chunklets were moved correctly.
Did you get any errors on these two steps?
3 movepdtospare -f -perm -nowait <DiskID> Vacate all data from PD
5 movech -perm -ovrd X:Y OPTIONAL: If getting an error, move Chunklet manually
