Step 9: Run the SAN setup assistant
Now use the SAN setup assistant to complete the upgrade.
To run the SAN setup assistant:
1 Open Xsan Admin (in /Applications/Server/).
2 When the SAN setup assistant appears, click Continue in the Introduction pane.
3 In the Initial SAN Setup pane, select “Connect to existing SAN” and click Continue.
4 In the dialog that appears, enter the name or address of a metadata controller, enter an
administrator user name and password, and click Connect.
5 In the Add Computers pane, select the computers that belong to the SAN. If a
computer doesn’t appear in the list, click Add Remote Computer and add it.
6 In the Authenticate SAN Computers pane, enter the common administrator account
name and password for the SAN computers and click Continue. If computers have
different administrator accounts, choose “Authenticate to SAN computers one by one.”
7 In the Serial Numbers pane, add an Xsan 2 serial number for each computer in the SAN,
and then click Continue.
Step 10: Wait for the volume upgrade to finish
You can’t access a SAN volume until the file-system data structure upgrade finishes.
The file-system upgrade can take less than an hour for a small volume or more than a
day for a large one. You can monitor the process so you’ll know when you can continue
with the next step.
To check progress of the upgrade:
m Use the Console application (in /Applications/Utilities/) to scan the contents of the
controller’s system log for entries containing the string
RPL_Upgrade .
The upgrade status messages in the log look like this:

Important: Wait until the upgrade is complete before going on to the next step. Don’t
use Xsan Admin until the upgrade is finished. The volume is unavailable and
unresponsive in Xsan Admin until the upgrade finishes.
