Operating Systems AIX How to restore rootvg archive after AIX 6.1 crash Post 302523785 by dukessd on Thursday 19th of May 2011 07:31:17 PM

Hi,

It sounds like you were very lucky with your recovery but I would be both dubious of relying on this for a production restore and also about how valid the recovery is on your test box for further development on this system.

For the ISO backup you'll find all sorts of problems like the 2GB file limit on VIOS install media meaning the image is split into more than one file, let alone more than one ISO although I suspect it will just create a second ISO for the remaining data. Good luck with that one, please let us know what you find out.

For your bootp issue you'll find VIOS and AIX installs and install media are quite different.
AIX installs from scratch or base filesets with a full base install process but VIOS media actually contains a backup or mksysb that is restored during the VIOS install, much like a mksysb migration of AIX and I suspect the linux bootp VIOS install relies on this.

You could probably create a generic AIX mksysb and use that to deploy AIX in the method suggested but I don't think it will work with AIX install media because the two installs are so completely different.

HTH and good luck, please keep us updated on your progress.

aset.restore

aset.restore(1M)					  System Administration Commands					  aset.restore(1M)

NAME

       aset.restore - restores system files to their content before ASET is installed

SYNOPSIS

       aset.restore [-d aset_dir]

DESCRIPTION

       aset.restore restores system files that are affected by the Automated Security Enhancement Tool (ASET) to their pre-ASET content. When ASET
       is executed for the first time,	it saves and archives the original system files in the	/usr/aset/archives  directory.	 The  aset.restore
       utility reinstates these files.	It also deschedules ASET, if it is currently scheduled for periodic execution. See  asetenv(4).

       If  you	have  made changes to system files after  running ASET, these changes are lost when you run  aset.restore. If you want to be abso-
       lutely sure that you keep the existing  system state, it is recommended that you back-up your  system before using  aset.restore.

       You should use  aset.restore, under the following circumstances:

	      You want to remove ASET permanently and restore the original system (if you want to deactivate ASET, you can remove it from schedul-
	      ing).
	      You are unfamiliar with ASET and want to experiment with it.  You can use aset.restore to restore the original system state.
	      When  some  major  system  functionality	is  not working properly and you suspect that ASET is causing the problem; you may want to
	      restore the  system to see if the problem persists without ASET.

       aset.restore requires root privileges to execute.

OPTIONS

       The following options are supported:

       -d aset_dir     Specify the working directory for ASET. By default, this directory is /usr/aset. With this option  the  archives  directory
		       will be located under aset_dir.

FILES

       /usr/aset/archives      archive of system files prior to executing aset
