I need to install a new server using mksysb on NIM, which we have done before. But this time there is a little difference - one disk hdisk0 on rootvg is bad and missing.

I checked the /image.data, it includes the below information:

1. grep VG_SOURCE_DISK_LIST /image.data

VG_SOURCE_DISK_LIST= hdisk0 hdisk3

1. grep LV_SOUR /image.data

LV_SOURCE_DISK_LIST= hdisk0 hdisk1 hdisk3
LV_SOURCE_DISK_LIST= hdisk0 hdisk1 hdisk3
LV_SOURCE_DISK_LIST= hdisk0 hdisk1 hdisk3

From the above output we can see, the missing disk hdisk1 is not in the VG_SOURCE_DISK_LIST, but it still is in the LVSOURCE_DISK_LIST.

I also checked the /bosinst.data, the hdisk1 has been removed and is not there.

On the new system to install, there are 2 hdisks.

My question is, will the installation successfully if I just follow the common NIM install procedure? or can I do it by setting the “Force Unattended Installation Enablement?” to "No" and specifying the new hdisks?

sure you can. even if your mksysb image comes from mirrored system you can extract and modify image.data from your mksysb for single disk restore (one mirror copy for each LV, LPs = PPs...) create image_data NIM resource with such modified image.data and then install system on single disks. I did it hundred times....

there are many ways to restore such AIX system mksysb....

Thank you very much.
Will I have to extract the image.data and modify it, or just restore to a new server with one disk less without needing modifying the image.data?
