Cloned HDD doesn't boot and cannot mount because VG is rootvg

    Hello,

    First of all, I introduce me. I work as a technical consultant IT departmet. Recently, we received an old IBM RS/6000 system 44P / 170 model with AIX 4.3.3 installed.

    Server boots, but unfortunatelly, Hard Disk has physical fails and cannot get (via FTP) two large (1024 MB) files we need. So we attached the hard disk on to a Linux box with a SCSI U160 controller, and extracted with dd_rescue tool an image of this hard disk. Then, we bought an equal Hard disk and restored that image to it.
    Now, that disk doesn't boot. It hangs at boot time, and show a 554 error on LCD display. I tried to restore boot with the AIX 4.3.3 CD rescue console, but disk doesn't boot.

    I only need to mount a logical volume to extract info, but when I connect two hard disks, and boot with broken hard disk, I cannot import VG from hdisk1, because VG name is rootvg.!!!!!

    Is there any way to change the name of VG of hdisk1 ??? How??
    Is there any way to boot from AIX 4.3.3 CD and set up networking, and enable FTP to copy the two files I need??
    Is there any way to mount a partition (Logical Volume) from the hdisk1 into system if both hdisk0 and hdisk1 has rootvg VG as name???
    Thank you very much. Any help were apreciated.

    if you boot from cd ou network(nim) you should be able to import the vg and mount the filesystems
    also, you should be able to manually configure the network interface and do your ftp-transfer

    and even if you booted from the other disk you should be able to import the vg on the other disk
    there is no vg-name written on the disks!
    just do importvg -y some_vg_name
    it will rename the lvs that the "new" vg has that the system already had
