I am trying to do an alt_disk_install (migration) of a 4.3.3 system to 5.1 ML 07. The original OS disks (hdisk0 and hdisk1) were only 4 GB and couldn't hold much more data, so we had to add two 18 GB disks to the system. I mirrored the OS to one of the 18 GB disks, did a bosboot -ad hdisk2, and broke the rootvg mirror, taking hdisk0 and hdisk1 out of the VG.
This left hdisk2 as the sole disk in rootvg. It has all the necessary LVs, including hd5. The command bootinfo -d gives the result hdisk0.
I started the alt_disk_install and got this error message at the beginning:
0301-168 bosboot: The current boot logical volume, /dev/hd5, does not exist on /dev/hdisk0.
I called IBM and they said it would be OK, because I could see that NIM had created alt_hd5.
Two hours later, at the end of the alt_disk_install process, I got this message:
Creating client boot image.
bosboot: Boot image is 17108 512 byte blocks.
Writing boot image to client's alternate boot disk hdisk3.
dd: 0511-053 The write failed.
: There is a request to a device or address that does not exist.
0505-184 nimadm: Error writing client boot image.
Cleaning up alt_disk_migration on the NIM master.
Does anyone have any ideas? Should I have used this bosboot command: bosboot -ad /dev/hdisk2? Should I boot off hdisk2 before I attempt the alt_disk_install again so the system will see that hdisk2 is bootable?
I've sent this info into IBM, but am hoping I can get a quick answer from this forum.
Thanks for any help you may give me.
