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.
