migration install question

[Mag0007]

Will migration install give me the choice of upgrading AIX on a certain hdisk?

For example, my current system running 4.3.3 has rootvg mirrored, and I will break the mirror like this:

rmlvcopy hd5 1 hdisk1
rmlvcopy hd6 1 hdisk1
rmlvcopy hd8 1 hdisk1
rmlvcopy hd4 1 hdisk1
rmlvcopy hd2 1 hdisk1
rmlvcopy hd9var 1 hdisk1
rmlvcopy hd3 1 hdisk1
rmlvcopy hd1 1 hdisk1

reducevg hdisk1

bosboot -ad /dev/hdisk0

bootlist -m normal cd0

Is this correct? am I missing anything? Will migration install give me a choice of installing AIX 5.2 on hdisk1?

No, what you are trying to do is part of the alt_disk_install functionality. WHen you break the mirror with hdisk1 your only option would be a fresh install on hdisk1 or a migration of hdisk0.

Using alt_disk_install will give you the ability to migrate one of the OS disks while leaving the other untouched and fully bootable to your current configuration.

I don't have access to another AIX server to create a NIM server for alt_disk_install.

I guess I can just leave it mirrored, and run migration install :-(

You don't need nim to do an alt_disk_install. All nim does is automate the whole process for you.

I still need another server AIX server for alt_disk_install.

Would a Sun server be usefull?

 

[hirschaj]

I don't understand why you think you need another server?

Hmm, so If I can do alt_disk install using CDs.

Do I do:
smitty alt_install -> Install mksysb on an Alternate Disk
or
smitty alt_install -> Clone the rootvg to an Alternate Disk

Remember, I will be upgrading from 4.3.3 to 5.2

 

[hirschaj]

You would clone rootvg to an alternate disk. How about you contact me thru my website and I can give you a document I have been working on about how to do this. If all goes well I can add it to the document repository here.
