Choosing a clustered upgrade procedure

Which procedure to use for clustered system upgrades  

The procedure you use to download Data ONTAP to clustered storage systems depends on the storage system type and the kind of upgrade--nondisruptive or standard.

• Nondisruptive upgrades are most appropriate for the following circumstances:
  • Your storage systems use CompactFlash cards (F825 and F880 storage systems, and FAS270, FAS900, and FAS3000 series storage systems).
  • You are upgrading to the Data ONTAP 7.1 release family from Data ONTAP 6.5.3 or later, or you are upgrading within the Data ONTAP 7.1 release family (for example, from Data ONTAP 7.1 to 7.1P1).
  • You are using RAID-DP or there is no disk firmware upgrade associated with the software upgrade.
  • High availability of storage system services is critical.

  For instructions on performing nondisruptive upgrades from the Data ONTAP 7.0 release family (for example, from Data ONTAP 7.0.0.1 to 7.1), see Nondisruptive upgrades from the Data ONTAP 7.0 release family.

  For instructions on performing nondisruptive upgrades from the Data ONTAP 6.5 release family (for example, from Data ONTAP 6.5.4 to 7.1), see Nondisruptive upgrades from the Data ONTAP 6.5 release family.

  For instructions on performing nondisruptive upgrades within the Data ONTAP 7.1 release family (for example, from Data ONTAP 7.1 to 7.1P1), see Nondisruptive upgrades within release families.

  Note
  If you are planning to perform a nondisruptive upgrade on a system with FCP or iSCSI hosts, see About nondisruptive cluster upgrades.

• Standard upgrades are most appropriate when you can schedule downtime for major software changes.

  You must use standard upgrade procedures when you upgrade to Data ONTAP 7.1from releases earlier than Data ONTAP 6.5.3

  For instructions on performing standard upgrades, see the section appropriate to your storage system type:

  • Downloading Data ONTAP to clustered FAS270 storage systems and FAS3000 series storage systems
  • Downloading Data ONTAP to clustered F810, F820, and F840 storage systems
  • Downloading Data ONTAP to clustered F810, F820, and F840 storage systems

For more information about which upgrade procedure is most appropriate for your storage systems and upgrade circumstances, see Planning for upgrading clusters.
