How to delete old configuration from array disk?

[hornacek]

I found 1 failed array disk and I have to change by good one. Unfortunately, the good one I have it was member of raid10 disk array before moving to the other site. It's still carrying the old configuration and I can't include it to this new SSA Raid array. Below is the message that I got from smitty.

DC7C41BEA00E4CO DC7C41BEA00E4CO free unknown 0 raid_10

hdisk2 1D4F4268B1F44CO system good 72.9GB raid_10

hdisk3 1D4F4268B2364CO system degraded 145.8GB raid_10

Please tell me how to delete old configution from array disk and add it to new SSA Raid array.

I think you need to clear the VGDA on that disk if i'm not mistaken! coz logically the VGDA on that disk is still pointing to the old array! use the disk's PVID as follows:

Try one
of the following, (note: reducevg updates the VGDA but not the ODM).

reducevg -f <vgname> <pvid>

ldeletepv -g VGid -p PVid
      -g Required, specify the VGid of the volume group you are
         removing the physical volume from
      -p Required, specify the PVid of the PV to be removed

Good luck
