Upgrading the IBRIX software to the 6.1 release
This section describes how to upgrade to the latest IBRIX software release. The Fusion Manager
and all file serving nodes must be upgraded to the new release at the same time. Note the following:
• Upgrades to the IBRIX software 6.1 release are supported for systems currently running IBRIX
software 5.6.x and 6.x.
NOTE: If your system is currently running IBRIX software 5.4.x, first upgrade to 5.5.x, then
upgrade to 5.6.x, and then upgrade to 6.1. See “Upgrading the IBRIX software to the 5.5
release” (page 160).
If your system is currently running IBRIX software 5.5.x, upgrade to 5.6.x and then upgrade
to 6.1. See “Upgrading the IBRIX software to the 5.6 release” (page 157).
• Verify that the root partition contains adequate free space for the upgrade. Approximately
4GB is required.
• Be sure to enable password-less access among the cluster nodes before starting the upgrade.
• Do not change the active/passive Fusion Manager configuration during the upgrade.
• Linux 9000 clients must be upgraded to the 6.x release.
NOTE: If you are upgrading from an IBRIX 5.x release, any support tickets collected with the
ibrix_supportticket command will be deleted during the upgrade. Before upgrading to 6.1,
download a copy of the archive files (.tgz) from the /admin/platform/diag/
supporttickets directory.
Online upgrades for IBRIX software 6.x to 6.1
Online upgrades are supported only from the IBRIX 6.x release. Upgrades from earlier IBRIX
releases must use the appropriate offline upgrade procedure.
When performing an online upgrade, note the following:
• File systems remain mounted and client I/O continues during the upgrade.
• The upgrade process takes approximately 45 minutes, regardless of the number of nodes.
• The total I/O interruption per node IP is four minutes, allowing for a failover time of two minutes
and a failback time of two additional minutes.
• Client I/O having a timeout of more than two minutes is supported.
