6. Run soft:history –dt or soft:history –dt --cluster to verify that the node is

updated with the latest ION Accelerator software.

7. If you are using HA mode, repeat this procedure on the second node.

8. When you are finished with the update(s), log out of the CLI. The system will

automatically reboot.

9. Log back in to the CLI to use the updated software,

To revert to a previous version of the software, run

soft:version, then soft:revert, then

soft:version.

Software Update Flow

The basic flow of the software update process is illustrated in the diagram below.

The ION Accelerator software starts out in the initial state.

After the

software:upload command is executed, an

update is present in ION Accelerator’s dropbox (if verification

passes). The patch can be applied with the

software:apply

command, which either completes or fails. If it fails (failed

state in the diagram), the user can issue the

software:revert command to discard the patch, or issue

the

software:apply command again, if the issue

preventing the patch from succeeding has been fixed.

If you are using HA mode and want to wipe the existing

configuration on one or more nodes, you must upgrade both

nodes simultaneously. If you upgrade one node at a time,

then one node will propagate the data to the other, and data

won't be wiped out.
