Move disks inside 3PAR 7400

How can I move disk from one slot in 3par to another slot? I need to do this since there are few disks not installed as pairs inside cage. So I need to remove disk from one slot and install it into different cage to create pair. Already there is data on these disks.

You might be able to use movepd to move the chunklets off the PD, if you have enough spare space.

Then use "controlpd spindown", then move the drive to the new slot.

If "showpd -i" shows the original PD in the new slot, you're done.

The move_back_chunklet scheduled task will move them back.

Hi

try this procedure

 

  MovePD

 1) setpd ldalloc off <DiskID> --                                                          To stop data to drive - Repeat for all PDs

2) showpd -s                                                                                        Make sure disks are in Degraded state

3) servicemag start -log -nodisks <CageID> <Magazine>                 Take drives Offline

4) servicemag status -d                                                                       Wait untill servicemag returns "Succeeded"

5) Move PD from old C:M:D to new C:M:D                                          Move the PD from old position to new position

6) servicemag resume <NewCageID> <NewMagazine>                         Resume service on PDs

7) servicemag status -d                                                                       Wait untill servicemag clears

8) servicemag clearstatus <OldCageID> <OldMagazin>                         Clear the Status of the servicemag operation

9) servicemag unmark <OldCageID> <OldMagazin>               Unmark the Posision of the old PD after the servicemag operation

10) Redo Steps 3-9 for all PDs

 11) setpd ldalloc on <DiskID>                                                   Resume data to drive (after all PDs are online) - Repeat for all PDs

Hi Dennis, Thanks for the reply.

What are the options that I need to use with movepd?

Do I have to use removespare after the movepd command?

Probably just -nowait.  -devtype if not enough spare space.

I don't think so, that's only needed for dismisspd.
