sap_hana_sr_takeover
2+
=====================
3+
4+
This role can be used to ensure, control and change SAP HANA System Replication
5+
6+
Requirements
7+
------------
8+
9+
This role requires SAP HANA System Replication configure, e.g. using the community.sap_install.sap_ha_install_hana_hsr role
10+
11+
Role Variables
12+
--------------
13+
14+
The follwoing variables are mandatory for running this role unless a default value is specified
15+
16+
| Variable Name | Description |
17+
|-------------------------------------|-----------------------------------------------------------|
18+
| sap_hana_sr_takeover_primary | Server to become the primary server |
19+
| sap_hana_sr_takeover_secondary | Server to register as secondary. The role can be run twice if more than one secondary is needed by looping over this variable |
20+
| sap_hana_sr_takeover_sitename | Name of the site being registered as secondary i |
21+
| sap_hana_sr_takeover_rep_mode | HANA replication mode (defaults to sync if not set) |
22+
| sap_hana_sr_takeover_hsr_oper_mode | HANA replication operation mpode (defaults to logreplay ) |
23+
| sap_hana_sid | HANA SID |
24+
| sap_hana_instance_number | HANA instance number
25+
26+
27+
Dependencies
28+
------------
29+
30+
`sap_hana_sid` and `sap_hana_instance_number` may already be set or used in other roles
31+
32+
Example Playbook
33+
----------------
34+
35+
If you have `hana1` and `hana2` configured for SAP HSR with SID RHE and instance 00 the following playbook
36+
ensures that `hana1` is the primary and `hana2` is the secondary
37+
38+
The role will fail if `hana1` is not configured for system replication (mode: none in `hdbnsutil -sr_state`).
39+
`hana1` needs to be primary or secondary in sync
40+
41+
The role will do nothing if `hana1` is the primary and `hana2` is the secondary.
42+
43+
It also ensures that the secondary HANA DB is started
44+
45+
```yaml
46+
- name: Ensure hana1 is primary
47+
hosts: hanas
48+
become: true
