Operating Systems AIX Mirrorvg to different multiple disks Post 302883982 by rbatte1 on Friday 17th of January 2014 05:03:00 AM

There is no need to mirror, sync then un-mirror. You can:-
Code:
extendvg appvg hdisk3 hdisk4
migratepv hdisk1 hdisk3
migratepv hdisk2 hdisk4
reducevg appvg hdisk1 hdisk2

The migration phases will take a long time (same as a mirror and sync) but it's less prone to error. I'm assuming that the target disks are at least the same size as the source.

You may want to consider stopping the database and HA too, but test this elsewhere and see if you need to take services down. It might be fine as the OS maintains access to the LV even with updates happening. I'm just very cautious.

I hope that this helps.

Re-using disks

I would like to know if I can move the disks from a V240 chassis into a V440 chassis to use the increased resources (CPU & Memory) to boost performance. I know you can move disks between V210/240 chassis's, but I'm not sure if this would work between 240s & 440s. Any help would be much appreciated. (4 Replies)

NAME
SVK::Help::Intro - Introduction to svk DESCRIPTION
svk is an open source distributed version control system which is designed to interoperate with Subversion. Like other version control systems, it keeps track of each change you make to a project and allows you to maintain multiple parallel tracks of development. svk also has a number of powerful features which are rarely found in other version control systems. svk has been designed from the ground up to support development models that are simple and intuitive for software developers. It has advanced smart branching and merging semantics that make it easy to maintain multiple parallel lines of development and painless to merge changes across branches. svk's built in patch manager makes it easy for non-committers to share changes among themselves and with project maintainers svk provides powerful support for distributed development. Every svk client is capable of fully mirroring remote Subversion repositories so that you have full access to a project's history at any time, even when they are off the network or on the wrong side of a firewall. You can branch a remote project at any point in that project's history, whether or not you have write access to that project's repository. Later, you can integrate changes from the project's master server (usually with a single command) or push your branch up to another Subversion repository. GETTING STARTED
svk has a rich command line interface that can be somewhat daunting at first. the following few commands are all you'll need for day to day operation. svk mirror First, you'll need to mirror a remote repository. This sets up a local copy of that repository for you to branch from, merge to and otherwise poke at. The local path is sometimes called a "depot path." svk mirror svn://svn.example.com/project_x //mirror/project_x svk sync When you've set up a new mirror or want to get some work done without a network connection, sync your local repository with upstream repositories. svk sync //mirror/project_x svk checkout When you want to get some work done, you can checkout a working copy to make changes. cd ~/svk-checkouts svk co //mirror/project_x If you want to work offline, you can create a local branch cd ~/svk-checkouts/project_x svk branch --offline svk add, svk delete and svk move As you work on the files in your working copy, feel free to add new files, delete existing files and move files around. cd ~/svk-checkouts/project_x svk add Changelog svk move badly_named_file.c well_named_file.c svk delete .README.swp svk commit When you're done, just commit your changes to your local repository, whether or not you have network. If you commit to a mirrored path, rather than a local branch, you'll need to be able to access the path's upstream subversion server, but the commit will be sent to the server instantly. svk commit svk pull Life doesn't stop when you make a local branch. From time to time, pull down changes from the upstream repository. cd ~/svk-checkouts/project_x svk pull svk push When you're ready to share your changes with the world, push them to the upstream repository. cd ~/svk-checkouts/project_x svk push To see a full list of svk's commands, type "svk help commands". For help with a specific command, just type "svk help command". The svk wiki (<http://svk.bestpractical.com>) is a great place to find the latest svk tips, tricks and updates. If you run into trouble using svk, the wiki's the right place to start looking for help. perl v5.10.0 2008-09-13 SVK::Help::Intro(3)
