Configuration Verification

Configuration Verification

After the Oracle hosts scan for LUNs, confirm the disk and database information and restart the database services to check whether heterogeneous storage resources are centrally managed.

Procedure

  1. Check the mapping relationship between host hdisk IDs and LUN WWNs.
    1. Before eDevLUN mappings are created, the mapping relationship between the EMC VNX5500 LUN WWNs and the Oracle host hdisk IDs can be obtained according to 1.a of Configuration Operations.
    2. Log in to each IBM Power 740 server (Oracle host), and run the lspv-u command as user root to query the mapping relationship between the Oracle host hdisk IDs and the OceanStor 2200 V3/2600 V3 eDeVLUN WWNs.
    3. Log in to the DeviceManager, and query the mapping relationship between the OceanStor 2200 V3/2600 V3 eDeVLUN WWNs and the EMC VNX5500 LUN WWNs.

      1. In the navigation bar in the right part, select Provisioning > LUN.
      2. In the function pane in the upper part, view the eDevLUN WWNs.

    4. Compare the Oracle host hdisk IDs, the OceanStor 2200 V3/2600 V3 eDevLUN WWNs, and EMC VNX5500 LUN WWNs, and make sure they are matched.

      If the Oracle host hdisk IDs and EMC VNX5500 LUN WWNs are not matched after the OceanStor 2200 V3/2600 V3 eDevLUNs are mapped, delete all LUNs from the mapping view between the eDevLUNs and host. Then add LUNs one by one to the mapping view, and trigger a LUN scanning job on the host each time after a new LUN is added to the mapping view. In this way, the hdisk IDs are generated in a correct sequence.

  2. Add permissions to the host hdisks.

    Based on the hdisk permission information collected in 1.a of Configuration Operations, run the chown hdisk1 -R oracle:dba command to add permissions to the hdisks newly mapped from the eDevLUNs.

  3. Verify the database OCR and Voting Disk information.

    Go to the bin directory as user grid. Run the ocrcheck command to verify the database OCR information. Run the crsctl query css votedisk command to verify the database Voting Disk information.

  4. Start the RAC cluster.

    1. Run the crsctl start cluster command as user root to start the cluster.
    2. Run the crs_stat -t -v command to confirm that all CRS services are operating properly.
    3. Run the ps -ef|grep d.bin command to confirm that the process is running.
    4. Run the srvctl status asm -n vioc1 command as user oracle to confirm that the ASM instance is in the normal state.

  5. Start upper-layer services.
