Service Manual

Upgrading if MAPS was installed, but not enabled
If MAPS is installed on the switch but is not enabled at the time the firmware is upgraded, after the
upgrade MAPS will be enabled either with the active policy named in the configuration, or if there is no
active policy named, then using the default conservative policy “dft_conservative_policy”. If MAPS was
licensed but not enabled, you can re-enable MAPS with one of the default policies or a converted
Fabric Watch policy (if Fabric Watch was licensed before upgrade) based on the Fabric Watch custom
thresholds that have been converted to MAPS policies before the upgrade.
If MAPS gets enabled implicitly (without the Fabric Vision license), then any existing user-defined
configurations are not initialized. After installing the Fabric Vision license, you can use one of the
following setups to enable MAPS with a user-defined configuration:
• Enable MAPS using a different policy in all logical switch contexts.
• Enable MAPS by downloading a user-defined policy containing user-defined configurations.
Upgrading if MAPS was installed and is enabled
If MAPS is installed and enabled on the switch, then MAPS will continue to monitor the fabric
afterwards with no change in operation. MAPS will be enabled with the same active policy that was
previously in force on each logical switch and will continue to monitor the fabric based on that policy.
Upgrading firmware on Fabric Watch-licensed switches
On switches that have Fabric Watch licensed and are explicitly using Fabric Watch monitoring,
upgrading to Fabric OS 7.4.0 is possible with or without migrating to MAPS. However, you must
migrate to MAPS prior to upgrading in order to use any custom Fabric Watch threshold configurations,
and to continue to be able use the monitoring service non-disruptively after the upgrade.
ATTENTION
Upgrading without converting Fabric Watch configurations to MAPS custom policies will result in the
loss of any custom threshold configurations.
To migrate from Fabric Watch thresholds to MAPS policies, complete the following steps before
upgrading to
Fabric OS 7.4.0.
NOTE
Without installing the Fabric Vision license, neither converting to MAPS custom policies nor migrating
to MAPS is allowed.
1. Enter licenseshow to check if the Fabric Vision license or Fabric Watch plus Advanced
Performance Management (APM) licenses are available.
•
If only the Fabric Watch license is available, obtain and install an APM license.
• If only APM license available, obtain and install a Fabric Watch license.
• If neither is available, obtain and install a Fabric Vision license.
2. Convert Fabric Watch configurations to MAPS custom policies using the mapsconfig --fwconvert
command.
3. Enable MAPS with one of the custom policies or default policies available using the mapsconfig --
enablemaps -policy policy_name command.
