OS 8.7 Preparing for SW Upgrade Oracle ZFS Storage Appliance Customer Service Manual (Page 421) 1. Verify your current software version. 2. Remove extraneous system updates. 3. Check the most recent release notes for additional preconditions that should be observed for the software release. If skipping some software releases, also review the release notes from all applicable previous releases. 4. Disable non-critical data services. These services may include replication, NDMP, shadow migration, or others. Disabling these services can shorten the upgrade time, and ensures that the system has a minimal operation load during the update. 5. Create a backup copy of the management configuration to minimize downtime in the event of an unforeseen failure. 6. Ensure that any resilvering and scrub operations have completed. The scrub property indicates whether scrub or resilver operations are active or completed. 7. Ensure that there are no active problems. For more information, see Active Problems Display on page 39. 8. Perform a health check. See Checking System Health BUI, CLI. A health check is automatically run as part of the update process, but should also be run independently to check storage health prior to entering a maintenance window. If a problem is encountered, it needs to be corrected before the upgrade can continue. Refer to the Customer Service manual for directions on addressing any issues. 9. Schedule a maintenance window of at least one hour to allow for disruptions in storage performance and availability during update. - Upgrading Software on a Standalone Controller on page 422 - Upgrading Software on Clustered Controllers on page 427 Always keep backup or DR-site/Replica of your data Copyright 2016 Oracle and/or its affiliates.

OS 8.7 Deferred Updates Each update may come with new firmware or updates to external resources. In general, these updates are backward compatible and applied automatically without user intervention. There are exceptions, however, for non-reversible updates. These updates involve updating a resource external to the system software in a way that is incompatible with older software releases. Once the update is applied, rolling back to previous versions will result in undefined behavior. For these updates, you will always be given an explicit option of applying them automatically during upgrade or applying them after the fact. They are therefore referred to as "deferred updates".
