Error description

  • When multibos is used on a mirrored rootvg, the new lv
    including bos_hd5 will be created with mirrors. But
    the bootlist will be set and reset only on the first
    mirror
    copy.
    For example if system is booted from bos_hd5 which is
    mirrored on hdisk0 & hdisk1.
    multibos -RX run correctly, but then bootlist -om normal
    returns :
    hdisk0 blv=bos_hd5
    hdisk0 blv=bos_hd5
    and bootlist -m normal hdisk0 hdisk1 fails with :
    0514-229 bootlist: Multiple boot logical volumes found on
    disk 'hdisk1'.
    Use the 'blv' attribute to specify the one from which to
    boot
    

Local fix

  • Manually set the bootlist correctly.
    Use chpv -c, & bosboot on the second mirror disk after
    multibos -R operation, then set the bootlist manually.
    

Problem summary

  • After a multibos remove operation on a mirrored rootvg system
    the mirrored boot volumes are not properly removed.
    

Problem conclusion

  • Modify the multibos bootlist and logical volume to handle the
    mirrored disk.
