Archived - About the Xsan 1.2 Updates

This article has been archived and is no longer updated by Apple.

There are four different software updates available for Xsan 1.2. These updates apply to Mac OS X client and Server versions 10.3.9 and later.

Installation

The following updates are available for Xsan 1.2, which can be installed using Software Update or by downloading a standalone update installer from Apple Downloads:

  • Xsan 1.2 Update for 10.4
  • Xsan 1.2 Update for 10.3.9
    Of the two updates above, you only need to install the one that corresponds to your operating system version.
  • Xsan Admin 1.2 Update
    Required for Xsan 1.2 administration (and is also recommended for Xsan 1.0 administration) and only needs to be installed on admin computers.
  • Xsan 1.2 Uninstaller

Important Notes- Read Before Continuing

  • Before Installation
    For the Xsan 1.2 Update for 10.3.9 and the Xsan 1.2 Update for 10.4, you must already be running Xsan 1.0.1 or 1.1. If you're still on Xsan 1.0, stop now and update to 1.1 before continuing.

  • After Installation
    To avoid a certain stability issue over the long term, you should run the cvfsck command on each Xsan volume, after the MDCs have been updated with Xsan 1.2 Update for 10.3.9 or Xsan 1.2 Update for 10.4. Before continuing, please see the full explanation here.

  • Metadata Controller (MDC) software version
    Whether you are running Panther or Tiger systems, your MDCs must always have software versions (both Xsan and Mac OS) that are equal to or more recent than the most recent client versions. Specifically, that means: If any client in your Xsan network is running Xsan 1.2 on Mac OS X 10.4.3 or later, then your metadata controllers (MDCs) must also be updated to Xsan 1.2 on Mac OS X 10.4.3 or later; If any client in your Xsan network is running Xsan 1.2 on Mac OS X 10.3.9, then the MDC must run Xsan 1.2 on 10.3.9.
