The storage section in the SAP HANA global.ini file contains the references from the SAP HANA storage partitions to the storage LUNs. PowerMax uses the UUID of the LUN to identify the correct storage devices.
You can identify the UUIDs using either of the following two methods:
server01: ~ # multipath –ll | grep –B1 512G
The command returns:
3600000970000196701016533030303141 dm-35 EMC ,SYMMETRIX
Size=512G features='0' hwhandler='0' wp=rw
The string 3600000970000196701016533030303141 is the UUID of the corresponding storage LUN. Linux adds a preceding 3 to the storage UUID.
C:\Windows\system32>symdev –sid 016 list –wwn | findstr 01A
The command returns:
0001A Not Visible SRDF1+TDEV 60000970000196701016533030303141
Note: SYMCLI displays the UUID without the preceding 3.
The SAP HANA global.ini file should look like the example in the following figure:
Note: If SAP HANA must start at the secondary site with the replicated R2 devices or the linked target devices, ensure that the storage section of the global.ini file contains the UUIDs pointing to the R2 or linked target devices.
