 Solution:

We will get the above error only if the rootvg was mirrored priror to taking the mksysb.

As long as your rootvg was mirrored you can break the mirror and retry the installation. You need to edit image.data so that you can use it to restore to a single disk.

we need to manually break the mirror in the mksysb with a custom image.data file.

#mkdir /export/idata

#cd /export/idata

#restore -xqvf // ./image.data

#vi /export/idata/image.data

 for each lv_data stanza.

   -Change the COPIES=2 to COPIES=1

   -Note the size of the LPs=XX value

   -change the PP=YY to match the Ps=XX value

Define a customized image_data resource:

#smitty nim_mkres

>>Resource Type: image_data

>>Resource Name: [nomirror_idata]

>>Resource Type: image_data

>>Server to Resource: [master]

>>Location of Resource: [/export/idata/image.data]

From the steps which you have you shoud go back and use the following migration command.

#nimadm -s -l -i -j -Y -T -O -N
