Hello,

I have a system boot from SAN now and want to migrate it to local drives (via mirrorvg).

The problem is them mksysb command fails with error:

0516-1259 mirrorvg: None of the available disks support booting on 

this specific system or the boot logical volume already exists on the specified disk. If these are 

new bootable disks and you have not rebooted since configuring them. You may 

try exporting LVM_HOTSWAP_BOOTDISK=1 and run 

this command again to override 

this condition. 0516-1200 mirrorvg: Failed to mirror the volume group.

The candidate disks are:
hdisk2 U787B.001.DNW7D64-P1-C3-T1-L5-L0 16 Bit LVD SCSI Disk Drive (73400 MB)
hdisk3 U787B.001.DNW7D64-P1-C3-T1-L8-L0 16 Bit LVD SCSI Disk Drive (73400 MB)

Both the same type:
Machine Type and Model......HUS103073FL3800
FRU Number..................80P6320
The are no newer microcode for these disks.

1. bootinfo -B hdisk2

0

1. bootinfo -B hdisk3

0
Anyone has idea and can explain why these local SCSI disks are not booteable?
best regards,
Pc

Ok, I fixed the issue.

Problably this was a feature of adding dynamically internal disks (DLPARing) to the LPAR.

To fix it I had shutdown the LPAR and activated it once again and bootinfo -S returns now 1 for both new disks.

Yes. When you add a SCSI/SAS disk with DLPAR Aix does not recognize as bootable. You can reboot the lpar for recognize the disk bootable. Altought you can mirror the rootvg on it and create the bosboot and if you can force this disk as boot disk all run well.
