aafter using ldm to add to my primary/secondary config,  i lose those on system getting power off/  on.

e.g.   I ran these commands and was able to log to guest and create zfs file system

ldm add-vdsdev  /dev/rdsk/c0t5002361004726910d0s2 lun5_v004@primary-vds0
ldm add-vdisk   vdisk5_v004 lun5_v004@primary-vds0 nxu22dbsorcv004

ldm add-vdsdev  /dev/rdsk/c0t5002361000339023d0s2 lun6_v004@secondary-vds0
ldm add-vdisk vdisk6_v004  lun6_v004@secondary-vds0 nxu22dbsorcv004

then after stop /SYS

power off system

my systems came online  but when I checked ldm list -l  it did not show the shared disks above.
