If there is a mismatch on your system, you will see errors when connecting to ports 1234 and
9009. To correct this condition, see “Moving the management console VIF to bond1”
(page 94).
Offline upgrades for X9000 Software 5.5.x to 6.0
The upgrade from X9000 Software 5.5.x to 6.0 is supported only as an offline upgrade. Because
it requires an upgrade of the kernel, the local disk must be reformatted. Clients will experience a
short interruption to administrative and file system access while the system is upgraded.
There are two upgrade procedures available depending on the current installation. If you have an
X9000 Software 5.5 system that was installed through the QR procedure, you can use the automatic
upgrade procedure. If you used an online upgrade procedure to arrive at your X9000 Software
5.5 system, you must use the manual procedure. To determine if your system was installed using
the QR procedure, run the df command. If you see separate file systems mounted on /, /local,
/stage, and /alt, your system was quick-restored and you can use the automated upgrade
procedure. If you do not see these mount points, proceed with the manual upgrade process.
• Automatic upgrades. This process uses separate partitioned space on the local disk to save
node-specific configuration information. After each node is upgraded, its configuration is
automatically reapplied.
• Manual upgrades. Before each server upgrade, this process requires that you save and back
up the node-specific configuration information from the server onto an external device. After
the server is upgraded, restore the node-specific configuration information manually.
NOTE: The automatic upgrade procedure can be used only if all nodes in the cluster were
originally installed with the 5.5 release. If you upgraded any nodes in the cluster from the 5.4
release to the 5.5 release, you must use the manual upgrade procedure.
The upgrade takes approximately 45 minutes for X9320 and X9720 systems with a standard
configuration.
Automatic upgrade procedure
All file serving nodes and management consoles must be up when you perform the upgrade. If a
node or management console is not up, the upgrade script will fail.
IMPORTANT: Before performing the upgrade, complete the following steps:
• Note any custom tuning parameters, such as file system mount options. When the upgrade is
complete, you can reapply the parameters.
• Stop any active Remote Replication, data tiering, or Rebalancer tasks running on the cluster.
(Use ibrix_task -l to list active tasks.) When the upgrade is complete, you can start the
tasks again.
• The 6.0 release requires that nodes hosting the agile management be registered on the cluster
network. Run the following command to verify that nodes hosting the agile management
console have IP addresses on the cluster network:
ibrix_fm -f
If a node is configured on the user network, see “Node is not registered with the cluster network
” (page 93) for a workaround.
Performing the upgrade
To upgrade all nodes in the cluster automatically, complete the following steps:
