INTRODUCTION This package provides a suite of modules for managing NetApp's NAS devices, commonly referred to as "filers". Although I consider the code to be very stable, the API should be considered experimental. The convention I will be following regarding non-compatible API changes is as follows. I'm using a major.minor release naming convention, and I will promise to NOT make non-backwards compatible changes between patches to a given major.minor release. However, in order to allow the API to evolve, it is entirely possible that non-backwards compatible changes will be made between minor releases. There is no guarantee that 2.003 will be 100% backwards compatible with 2.002, although such changes will be made only when justified. The author does not believe in infinite backwards compatibility. INSTALLATION To install this module, run the following commands: perl Makefile.PL make make test make install SSH vs TELNET This module is designed to be used with a password-free ssh configuration, which means you must have configured your filers with an ssh key such that you can run remote commands using: ssh [ ssh options ] $hostname $command without entering a password. In order to configure this, you need to install the public half of your ssh key on the filers directly. You can use this module with telnet, but this is less secure, since you have to find a way to access the plain text password from your code, and that usually means either embedding the password in the source code (the worst idea) or embedding it into a file somewhere. In addition, the error checking with telnet is far less robust, and there can only be one concurrent telnet session to a filer, so we recommend against using telnet for anything other than installing the ssh key. In a future release, the author hopes to provide a utility to automate the installation of the ssh key, using the telnet protocol, as both an example of using the API, and a means of helping others wean themselves from the use of telnet. TESTING The test suite is broken down into two separate sections: 10_passive and 20_active. The passive tests will change absolutely nothing on the filers. The goal of the passive tests is to run the query methods and the parsing code through as much input as possible, and these tests will walk through every aggregate, volume and qtree, among other object types, on each filer that has been configured for testing. As a result, they can be somewhat time consuming, depending on the number of filers, and the size of their configuration. The active tests, which are not yet implemented, will be destructive, and will test creating, modifying and destroying objects such as aggregates, volumes, qtrees, etc. The author expects to start adding active tests in one of the upcoming releases of this API. The tests are configured by specifying one or more filers to query in the file: ./t/lib/NetApp/Test.pm Please see that file for examples and documentation on how to customize the configuration. To summarize, you can either hack that file, or you can export a number of environment variables to control the test externally (this is what the author does, for example). DEPENDENCIES A bunch... See Makefile.PL, which will tell you about them anyway when it doesn't find them. Note that if you want to use the caching feature of the NetApp::Filer objects, this requires a patched version of Memoize::Expire. I have tried to get the owner of that code to accept a patch, but have been unable to get a response from him. Email me directly, and I'll be happy to provide the code.
