APAR status

Closed as program error.

Error description

    When 'synclvodm -Pv rootvg' is executed, it removes the
    link /dev/ipl_blv. This is a hard link to /dev/hd5.

    Subsequently when '/usr/sbin/savebase -v -d
    /dev/ipldevice'
    is executed, it errors out complaining that /dev/ipl_blv
    is missing.

    To recreate, execute
    1. synclvodm -Pv rootvg
    2. /usr/sbin/savebase -v -d /dev/ipldevice

Local fix

    One of the 2 workarounds can be used for this problem-

    1. Manually create the link before executing 'savebase'
    command.
       ln /dev/hd5 /dev/ipl_blv

    2. Execute savebase command without "-d" flag
       /usr/sbin/savebase -v

Problem summary

    synclvodm of a VG containing the primary boot LV will remove
    /dev/ipl_blv device and not remake it.  This link will be
    remade upon system reboot.

Problem conclusion

    Have synclvodm remake /dev/ipl_blv if it removes the primary
    boot LV's device.
