Mystery doing NIM alternate disk migration from 5.3 to 6.1

    Hi. I updated two servers from AIX 5.3 to AIX 6.1 using NIM alternate disk migration. The first worked fine. With the second, I lost everything under /home which was under rootvg.

    When I boot from hdisk0 AIX 5.3, all is there. When I boot off of hdisk1 AIX 6.1, only guest is under /home. I'm told migration doesn't touch /home.

    Any ideas??? Thanks!

    also note , i see customers create links for home , sometimes point to different mount point .
    which method you are doing the migration , i mean NIM alternate disk using mksysb to mksysb method or over the nerwork ? Do u have a option to priview the caching FS ?

    The problem seems to be resolved. Looks like a space issue. We had a huge number of old sa files under rootvg that made the mksysb very big. Also used the verbose output in the migrate which gave more information. For this server we migrated without the cache option, but subsequent migrates all went well using the same spot and lpp_source with cache. Cleaning up rootvg file systems ahead of time improves migrate time and reduces cache space needed.
