lvlnboot -v shows up some funnies, but i'm not laughing!

Hi

 

We have a live system which shows some extra disks as bootable which are not part of vg00:

 

root@server at /home/root =>lvlnboot -v
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
        /dev/disk/disk100 -- Boot Disk
        /dev/disk/disk103 -- Boot Disk
Boot: lvol1     on:     /dev/disk/disk100
                        /dev/disk/disk103
Root: lvol3     on:     /dev/disk/disk100
                        /dev/disk/disk103
Swap: lvol2     on:     /dev/disk/disk100
                        /dev/disk/disk103
Dump: lvol2     on:     /dev/disk/disk100, 0

lvlnboot: LIF information corrupt or not present on  "/dev/disk/disk87".
Use the "mkboot" command to initialize the LIF area.
Boot Definitions for Volume Group /dev/vg09:
Physical Volumes belonging in Root Volume Group:
        /dev/disk/disk81
        /dev/disk/disk87 -- Boot Disk
No Boot Logical Volume configured
No Root Logical Volume configured
No Swap Logical Volume configured
No Dump Logical Volume configured

 

Clearly VG00 contains disk100 and disk103.

 

disk87 is a LUN on an EVA and is part of an Application VG09:

 

root@apollo at /home/root =>vgdisplay -v vg09
--- Volume groups ---

   --- Physical volumes ---

   Proactive Polling           On

   Total PE                    2558
   Free PE                     0
   Autoswitch                  On
   Proactive Polling           On

 

Any ideas on how this might've happened, what effect this can have (if any), and maybe to to tidy this up?

 

Regards

Re: lvlnboot -v shows up some funnies, but i'm not laughing!

Maybe disk87 was created by using "pvcreate -B ...", but this is not something to worry about.

Hope this helps!

Backup all data, remove all LVOLs, remove disk from VG, re-create the PV (pvcreate without -B), add to VG, add LVOLs.


But why?
No need to do this.


See your other thread:
