Error description

  • If using mirrorvg/unmirrorvg to migrate rootvg from one
    disk to another, or using unmirrorvg to remove the disks
    to
    which  ipldevice is linked to replace a failing drive,
    ipldevice is not relinked to the remaining disk.
    If the old device is removed using rmdev -dl <hdisk>
    further commands using bootinfo like mkszfile will fail
    with :
    # /usr/bin/mkszfile
    0301-150 bosboot: Invalid or no boot device specified!
    usage:  bosboot ....
    A boot in that case would fail on led 554.
    

Local fix

  • relink ipldevice to the new boot disk after unmirrorvg.
    using :
    ln /dev/r<hdiskXX> /dev/ipldevice
    for example :
    ln /dev/rhdisk1 /dev/ipldevice
    

Problem summary

  • If unmirrorvg removes the bootlv from the previously booted
    hdisk (which /dev/ipldevice is linked to), then
    bosboot -ad /dev/ipldevice can write the boot image to the
    wrong disk, or fail if that disk has been removed.
    This can lead to issues during a reboot if not corrected.
    

Problem conclusion

  • Add code to unmirrorvg to detect this situation and remake
    /dev/ipldevice to point to a valid boot disk still in the
    boot lv.
