Re: [pca] rebuild patch level
Hi, Ihsan Dogan wrote: Is it possible to install only the missing patches on host a, which are installed on host b? A flash archive, as suggested by Michele, is definitely the best way to go. If that's not an option, you can get a list of all patches installed on host b (in the correct order) with ls -rt /var/sadm/patch/. You could then feed this list into pca -i on host a. Never tried that in a real-world scenario, though. E.g. some driver patches might not apply to host a, if it isn't the same architecture as host b. Martin.

Just to reiterate Martin's point here, to use a flash archive (flar) from one system and apply it to another both machines should be as closely matched as possible. They'll obviously need to have the same system architecture and ideally should be the same model (i.e. from one SunFire T2000 to another SunFire T2000), to ensure that the drivers from machine a will work on machine b. I've used flars to clone test systems before and have to say that they are extremely useful for scenarios that are suited to them. You need to be careful using flars with systems that have certain machine specific configurations. For example, suppose you have a machine - machine1 - that is running a web server and the web server's configuration file contains a reference to the hostname - say machine1.mydomain.com. If you take a flar of that machine and apply it to another similar system - machine2 - then the new system will have a web server configuration file with a reference to machine1.mydomain.com... Also, flars do not play well with zones, so if your machine is a Solaris 10 machine with zones, you may need to look for an alternative... HTH, -Don Martin.
[pca] rebuild patch level
Hi, I have to rebuild a system with a certain patch level. This mainly, because all the patches have to be approved by the software vendor first. Is it possible to install only the missing patches on host a, which are installed on host b? Ihsan -- ih...@dogan.ch http://blog.dogan.ch/

This mainly, because all the patches have to be approved by the software vendor first. You want clone the OS + patches installed on host A into host B? If the answer is yes, use Flash Archive command (man flar) to create a Gold Image of host A and install the host B by this image (flar archive file). See here[1] or here[2] fo other details. Is it possible to install only the missing patches on host a, which are installed on host b? Described here[3] is the same request? 1. www.sun.com/bigadmin/content/submitted/flash_archive.jsp 2. docs.sun.com/app/docs/doc/817-5668/flashinstall-10?a=view 3. www.mail-archive.com/pca@lists.univie.ac.at/msg00888.html Ihsan HTH Michele -- http://michelevecchiato.wordpress.com

Generating this could be a bit of a challenge, but combinations of showrev -p on one system, then editting the file, sorting out duplicates, etc, should get you there. pca -i file.txt -- regards, -glenn
