  • 1.  Mksysb Restore

    We are running AIX5.3 maint level 04. The original system runs a 64 bit kernel but a restore of its mksysb to another machine (same model and type) restores a 32 bit kernel. The sddpcm services would not start when trying to add the external disks. The kernel was changed to 64 bit but still could not get the sddpcm services/software to start. We tried reloading the bundle but that failed. Any ideas ? The new system does see the external storage, but the disks appear as defined and not available. The pcmpath commands just throw up errors and pcmsrv just doesn't start...

    in the bosinst.data file you'll need to add
    ENABLE_64BIT_KERNEL = yes

    this should work now

    when you restore the mksysb , there are a couple of way to ensure this but I don't want to go into that now .
    OR to save reinstalling you could just link the /unix file to
    lrwxrwxrwx 1 root system 21 Aug 10 14:16 /unix -> /usr/lib/bootunix_64

    and the same with /usr/lib/boot/unix
    ls -al /usr/lib/boot/unix
    lrwxrwxrwx 1 root system 21 Aug 10 14:05 /usr/lib/boot/unix -> /usr/lib/boot/unix_64

    run bosboot and reboot
