3PAR disk relocation without offload of disk

Hi to all,

I have got info that there is undocumented 3PAR CLI command with whom it is possible to move drives from one slot to another (like when It is needed to do relocation of disk during add-on to make equal number of disks in all enclosures) without using standard procedure to offload and remove all data from disk and then to move it.

It looks like that command is introduced in 3.2.x version of 3PAR OS but I can not find any info about it.

Standard procedure for relocation of disk can be very time consuming, so that is reason why I am trying to find solution. Something like on old EVAs when you had couple of sec to move disk from one drive slot to another ...

So I am assuming that this command shoud have parameters like when you move data you move from slot X to slot Y..... so that info about disk (metadata) is updated correctly ...

Tnx!
