Test Design of HA

The Design of HA automated test

Pre-requirements:

1. xcatmn1 is xcat MN and HA control node
2. xcatha1 and xcatha2 are 2 HA MN nodes
3. xcatcn is compute node managed by xcatha1 and xcatha2, it is used to test provision

Test cases:

test case file and other useful files(cfgha_mn and hosts file) are kept under /opt/xcat/share/xcat/tools/autotest/testcase/HA

Test case1: setup_2_new_HA_MN

Test case2: configure_exist_xCAT_MN_to_HA_MN

Test case1:setup_2_new_HA_MN

1. download xcatha.py, copy xcatha.py and cfgha_mn into /install/postscripts
2. backup xcatha1 and xcatha2 node definition
3. backup osimage definition rhels7.4-ppc64le-install-compute
4. create /opt/xcat/share/xcat/tools/autotest/testcase/HA/hosts, contains:
   • 2 HA nodes physical IP
   • VIP and hostname
   • control node
5. customize diskful osimage rhels7.4-ppc64le-install-compute, add /opt/xcat/share/xcat/tools/autotest/testcase/HA/hosts in synclists
6. Modify xcatha1 and xcatha2 postbootscripts, configure physical ip as static IP using confignetwork -s, add cfgha_mn in postbootscripts

chdef <xcatha> -p postbootscripts="confignetwork -s,cfgha_mn -l <nfs_server>:<shared_data_dir> -i <vip> -x s"

7. provison xcatha1 as standby HA MN node
8. provision xcatha2 as standby HA MN node
9. activate xcatha1 as primary HA MN
10. import diskless osimage from xcatmn1
11. define xcatcn in xcatha1
12. provision diskless xcatcn in xcatha1
13. deactivate xcatha1 as standby HA MN
14. activate xcatha2 as primary HA MN
15. provision diskless xcatcn in xcatha2
16. restore environment

Test case2:configure_exist_xCAT_MN_to_HA_MN

1. download xcatha.py, copy xcatha.py and cfgha_mn into /install/postscripts
2. backup xcatha1 and xcatha2 node definition
3. backup osimage definition rhels7.4-ppc64le-install-compute
4. create /opt/xcat/share/xcat/tools/autotest/testcase/HA/hosts, contains: 2 HA nodes physical IP, VIP and hostname, control node
5. customize diskful osimage rhels7.4-ppc64le-install-compute, add /opt/xcat/share/xcat/tools/autotest/testcase/HA/hosts in synclists
6. Modify xcatha1 and xcatha2 postbootscripts, configure physical ip as static IP using confignetwork -s
7. provision diskfull xcatha1 and xcatha2
8. install xCAT in xcatha1 and xcatha2
9. configure xcatha1 and xcatha2 as standby HA MN nodes

updatenode <xcatha> -p postbootscripts="cfgha_mn -l <nfs_server>:<shared_data_dir> -i <vip> -x s"

10. activate xcatha1 as primary HA MN
11. import diskless osimage from xcatmn1 in xcatha1
12. define xcatcn in xcatha1
13. provision diskless xcatcn in xcatha1
14. deactivate xcatha1 as standby HA MN
15. activate xcatha2 as primary HA MN
16. provision diskless xcatcn in xcatha2
17. restore environment
