Enable the SAP HANA Storage Connector API
The SAP Storage Connector API provides a way to call a user procedure whenever the SAP HANA
name server triggers a node failover. The API requires the files mentioned here.
Run the procedure on the master name server.
To activate the procedure in the event of a node failover, edit the global.ini file in <HANA
installdirectory>/<SID>/global/hdb/custom/config/ and add the following entry:
[Storage]
ha_provider = ucs_ha_class
ha_provider_path = /hana/shared/HA
server01:
# cd /hana/shared/<SID>/global/hdb/custom/config
server01:/hana/shared/ANA/global/hdb/custom/config #
ls -l
-rw-r----- 1 anaadm sapsys 90 Feb 15 11:22
global.ini
-rw-rw-r-- 1 anaadm sapsys 9560 Feb 15 11:23 hdbconfiguration_1
drwxr-x--- 3 anaadm sapsys 4096 Feb 15 11:22 lexicon
-rw-r--r-- 1 anaadm sapsys 128 Feb 15 12:34 nameserver.ini
server01:/hana/shared/ANA/global/hdb/custom/config #
server01:/hana/shared/ANA/global/hdb/custom/config #
vi global.ini
[persistence]
basepath_datavolumes=/hana/data/ANA
basepath_logvolumes=/hana/log/ANA
[storage]
ha_provider = ucs_ha_class
ha_provider_path = /hana/shared/HA
To activate the change, restart the SAP HANA database.
Test the IPMI Connectivity
Test the IPMI connectivity on all nodes. Note that 02 means power up, and 00 means power down.
mgmtsrv01:/
# ipmitool –I lanplus -H server01-ipmi -U sapadm -P cisco –t 0x24
raw 0x30 0x71 0x00
02 08 00 01 02 03 80 81 82 83
mgmtsrv01:/ #
Make sure that all nodes respond to the
ipmitool
command.
