System peer monitoring and handling:
It does peer health check by querying peer group list.
After failure is detected and the number of heartbeat
failure reaches the threshold, alarm will be raised.
After connection is back online, alarm will be cleared,
and will perform an audit to the peer groups that are associated
to the system peer.
Subcloud peer group audit and handling:
If the remote peer group's migration_status is in the 'migrating'
state, unmanage the subclouds of the local peer group.
If the remote peer group's migration_status is in the 'complete'
state, compare the subclouds on both ends.
If the remote end is in a 'managed+online' state,
set the local subclouds with the same region_name to
'unmanaged+secondary.'
If the remote peer group's migration_status is in the 'none' state,
set the migration_status of the local peer group to 'none' as well.
Batch rehome update:
When Subcloud Peer Group based batch rehoming is performed,
need to check if the associated System Peer is alive or not:
If yes, and the remote subcloud with same region_name is
being managed in peer site, need to unmanage it before
rehoming it to local site.
If not, this means the peer site is not available for the
subcloud management any more, rehoming can be performed
directly.
If the subcloud peer group priority is 0, will try to clear alarm
of FM_ALARM_ID_DC_SUBCLOUD_PEER_GROUP_NOT_MANAGED
after batch rehoming is complete.
Security enhancement:
Base64 encode/decode admin_password when save/load rehome_data
from DB.
Test Plan:
1. PASS - Add a system peer on DC0, unplug the OAM network
between DC0 and DC1. Alarm raised.
2. PASS - Reconnect the OAM network between DC0 and DC1,
previous alarm will be cleared.
3. PASS - Add a subcloud peer group on DC0.
Add two subclouds on DC0 under the subcloud peer group.
which should be in managed, online and complete states.
Add a system peer on DC0 pointing to DC1,
Add a peer-group-association associating the peer-group
and the system-peer above on DC0.
create another association in DC1, for system DC0 and the
peer group synced to DC1.
Shutdown DC0, perform the migrate operation on
subcloud-peer-group from DC1, after all subclouds have
been migrated and entered online managed states.
Power on DC0, check alarm like "Subcloud peer group
xxx is managed by remote system (peer_uuid=xxx) with
lower priority." has been raised.
Check the subcloud state on DC0, should be in 'secondary' state,
Perform the migrate operation on subcloud-peer-group from DC0.
After all subclouds have been migrated and entered online
managed states. Alarm is cleared.
Check subclouds on DC1, subcloud state should be in secondary state.
4.PASS - Migrate a subcloud peer group with 0 priority,
Before migrate, check alarm
FM_ALARM_ID_DC_SUBCLOUD_PEER_GROUP_NOT_MANAGED
exists.
After migration done, check alarm cleared.
5. PASS - When the remote peer group's migration_status is in the
'migrating' state (if DC0 comes back online while rehoming
is still in progress); DC0's subcloud will be auto set to 'unmanaged',
after DC1's migration is complete and all subcloud in 'managed+online',
DC0's subcloud will auto set to 'secondary'.
