Ron Stone f125a8b892 Remove spurious escapes (r8,dsR8) 
This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three

Manage Subcloud Groups

Subclouds can be organized into subcloud groups. These subcloud groups can control how subclouds are updated.

When a subcloud is created it is automatically added to the 'Default' subcloud group, unless the group is specified. Subclouds can be associated with a particular group when they are created, and that association can be changed to a different subcloud group, if required. To create a subcloud group, see, Creating Subcloud Groups <creating-subcloud-groups>.

For example, while creating a strategy, if several subclouds can be upgraded or updated in parallel, they can be grouped together in a subcloud group that supports parallel upgrades or updates. In this case, the max_parallel_subclouds, and subcloud_apply_type are not specified when the strategy is created, so that the settings in the subcloud group are used.

Alternatively, if several subclouds should be upgraded or updated individually, they can be grouped together in a subcloud group that supports serial updates. In this case, the max_parallel_subclouds, andsubcloud_apply_type are not specified when creating the strategy, and the subcloud group settings for max_parallel_subclouds (not applicable), and the subcloud_apply_type (serial) associated with that subcloud group are used.

For more information on creating a strategy for orchestration upgrades, updates or firmware updates, see:

  • To create an upgrade orchestration strategy use the dcmanager upgrade-strategy create command.
  • To create an update (patch) orchestration strategy use the dcmanager patch-strategy create command.
  • To create a firmware update orchestration strategy use the dcmanager fw-update-strategy create command.
