Highlights

Xsan 2.2 provides Snow Leopard compatibility, stability fixes, and the ability to replace AppleDouble files with new native extended attributes. It is compatible with 10.5.8 and 10.6.x, but it can only be installed on Intel Macs. PowerPC Macs running 2.1.1 can be part of Xsan 2.2 SAN, but only as clients, not MDCs.

Upgrade and Migration

If you are updating from 2.1.1 to 2.2 on an Intel machine running 10.5.8, this is a very straightforward release. Any other path can be tricky, and I'm sure we'll see many of you combining this update with an OS upgrade and/or hardware migration. Here are some key resources:

Upgrading Xsan 1.4.2 to Xsan 2 (public KBase summarizing the various paths, including 2.1 -> 2.2)

Xsan 2 Migration Guide (Second Edition) (provides detail for 1.4.2 -> 2.1)

Xsan 2 Migration Guide (Third Edition) (provides detail for 2.1 -> 2.2)

Important: the KBase is just a summary. It refers to the Migration guides, which provide details for each step.

One of the trickiest points is that you may not have installation media that works for your particular upgrade or migration scenario. That is why we are posting the Install Discs noted above. These disc images do not include a serial number, so you will use the serial number that came with their boxed version.

Example 1: Customer has Xsan 2.0 box and buys a new Mac Pro to replace an existing PPC machine on his SAN. The Mac Pro ships with Snow Leopard. The Xsan 2.0 installer will not run on SnowLeopard. Customer downloads the Xsan 2.2 Install Disc and installs it on the Mac Pro, using the serial number from the 2.0 box (which was previously used on the PPC machine the Mac Pro replaces.)

Example 2: Customer has an Xsan 1.4.2 SAN on Tiger (Intel) and buys Snow Leopard and Xsan 2.2. The in-place upgrade path requires installing Leopard and Xsan 2.0 as intermediate steps. The customer downloads the Xsan 2.0 Install Disc and uses the serial number from the new 2.2 box. If the customer does not have Leopard media, and/or Leopard Sever serial number in order to make this transition, they should contact AppleCare. These cases should be rare, since the hardware that can run both Tiger and Snow Leopard is limited.
