Hello,

I know that someone has already posted something similar, but my question still stands.

I am attempting to restore a VIO server from the nim_resources.tar file (created using the backupios command on the VIO server), but it is failing at the point of trying to boot the VIO server LPAR using the 'lpar_netboot' command. It is saying that the '-K' flag is an illegal option.

The NIM server is at 5300-08-04-0844, with required APAR IY85192 installed to allow the use of the 'installios' command from a NIM server.

The MAN page for 'lpar_netboot' command on the NIM server makes no reference to the '-K' flag, but the InfoCenter MAN page for 'lpar_netboot' for both AIX 5.3 & AIX 6.1 DO reference the '-K' flag.

Was this flag made available at a more recent TL or SP?

Thanks in advance.

The older 5.3 command reference pages do not mention -K but the newer ones do.

I have a 5.3 TL08 SP01 box and although I do not have the command / fileset installed I do have the man pages for it and there is no mention of the -K option.

I checked the AIX 5.3 TL release notes but there is no mention there either.

I can only assume it was introduced some time after TL08 SP01, probably after TL08 SP03 because it does not seem to be supported on your system.

The websphere team have some comments on the matter here:

If you need to specify a subnetmask in your environment then maybe you could perform the boot from ASMI or the HMC instead.

Thanks for the reply.

Unfortunately, as this VIO server LPAR is an IVM managed resource, I need to be able to specify the subnet mask as part of the installios command / restore process on the NIM server exclusively. I think it's time to raise a call with IBM as I cannot find any specific reference to the -K flag being added to the lpar_netboot command post SP4 on AIX 5.3.

Cheers.

UPDATE:

Having debugged the installios command (sh -x installios ~) it seems to call the lpar_netboot command on the HMC that manages the VIO LPAR. It is there (also) that the '-K' flag is not supported.

I have attempted to create a copied hacked version of the installios command on the NIM server (it's a shell script, not a C binary).
I have edited the line where it calls the lpar_netboot command (where you have a HMC attached to your system) and I have removed the reference to the '-K' flag. But there is nowhere then to specify the subnet mask as the HMC version of the lpar_netboot command does not have an equivalent flag to specify the subnet mask.

UPDATE:

I have checked out the lpar_netboot command flags via the InfoCenter for V7 of the HMC OS, and there is no reference to the '-K' flag.
I have yet to raise a call with IBM, but I thought I would check one more time just in case.
