Configuration Operations

Configuration Operations

After planning the network and services, complete specific configurations on the application servers and storage systems, so that storage resources on the local storage system and heterogeneous storage system can be centrally managed based on SmartVirtualization.

Procedure

  1. Collect information about the IBM Power 740 servers (Oracle hosts) before switching database services.
    1. Collect the file system and disk information.

      1. Run the lspv-u command as user root to record the mapping relationship between the EMC VNX5500 LUNs and the Oracle host hdisks.
      2. Run the lsattr -El hdiskx command to collect the properties of each Oracle host hdisk.

        x in the lsattr -El hdiskx command indicates a drive letter.

      3. Collect the file system information.

        Run the mount, df, and cat /etc/filesystems commands in sequence.

      4. Run the ls -l /dev |grep disk command to collect the permission information.

    2. Collect the database information.

      1. Run the ocrcheck command as user grid to collect the database ORC information.

        Then run the ocrconfig -showbackup command as user grid to back up the database OCR information. If any fault occurs, run the ocrconfig -restore command as user grid to restore the OCR information.

      2. Run the crsctl query css votedisk command to collect the Voting Disk information.
      3. Log in to the database as a system user and go to the ASM instance. Run the show parameter asm_diskstring command to collect the asm_diskstring settings in ASM. Run the select path from v$asm_disk; command to collect the disk information in the ASM disk groups.
      4. Run the archive log list; command to collect the Oracle archive mode.
      5. Run the select name from v$controlfile; command to collect the control file information.
      6. Run the select name from v$datafile; command to collect the data file information.
      7. Run the select member from v$logfile; command to collect the log file information.
      8. Run the select name from v$tempfile; command to collect the temporary file information.

  2. Stop database services on the Oracle hosts.
    1. Log in to the database as a system user and go to the ASM instance. Run the show parameter spfile command to view the ASM diskstring value.

      • If the current ASM instance is not using an spfile file, the value in the command output is empty. Then perform the following operations:
        1. Run the vi command to edit the $ORACLE_HOME/dbs/init+ASM.ora file and set asm_diskstring='/dev/rhdisk*'.
        2. Shut down the database and ASM instance.
      • If the current ASM instance is using an spfile file, the value in the command output indicates the location of the spfile file. Then perform the following operations:
        1. Go to the ASM instance. Run the create pfile from spfile; command to create a pfile file for the ASM instance.
        2. Shut down the database and ASM instance.
        3. Run the vi command to edit the $ORACLE_HOME/dbs/init+ASM.ora file and set asm_diskstring='/dev/rhdisk*'.
        4. Run the startup pfile='$ORACLE_HOME/dbs/init+ASM1.ORA'; command to start the ASM instance.
        5. Run the $mv $ORACLE_HOME/dbs/spfilesxsb1.ora $ORACLE_HOME/dbs/spfilesxsb1.ora.bak command to move the spfile file to another location.
        6. Run the create spfile from pfile; command to create an spfile based on the pfile.
        7. Shut down the ASM instance.

    2. Stop all CRS services.

      1. Run the crsctl stop cluster command as user root to shut down the cluster.
      2. Run the crs_stat -t -v command to confirm that all CRS services have been stopped.
      3. Run the ps -ef|grep d.bin to confirm that the process has been stopped.

    3. Shut down the Oracle hosts.

      1. Run the shutdown -Fr command to restart the operating system.
      2. Run the crs_stat -t command as user grid. Log in to the database as a system user. Run the select instance_name,status from v$instance; command to confirm that the database services are operating properly.
      3. Log in to the database as a system user. Run the shutdown immediate; and exit commands in sequence to shut down the database.
      4. Run the crsctl stop cluster command as user root to shut down the cluster.

  3. Log in to the EMC VNX5500 and delete its LUN mappings to the Oracle hosts.

    NOTE:

    For details, refer to the related EMC documentation.

  4. Log in to the OceanStor 2200 V3/2600 V3, and check whether the SmartVirtualization license is valid.

    Navigation path: Choose Settings > License Management.

  5. Change the network.
    1. Based on the network diagram shown in Figure 6-5, connect the OceanStor 2200 V3/2600 V3 to the existing network.
    2. Create zones on the Fibre Channel switches to ensure normal communication among the EMC VNX5500, the OceanStor 2200 V3/2600 V3, and Oracle hosts.

      NOTE:

      For details about how to create zones on the Fibre Channel switches, refer to the user manual of the Fibre Channel switch.

  6. Install Huawei UltraPath on the Oracle hosts.

    NOTE:

    For details about how to install Huawei UltraPath, see OceanStor UltraPath for AIX V100R008 User Guide.

  7. Set up a logical connection between the OceanStor 2200 V3/2600 V3 and the EMC VNX5500.

    In the EMC VNX5500 storage system, map LUNs to the OceanStor 2200 V3/2600 V3 storage system. For details, see the related EMC VNX500 user guide.

  8. Enable the OceanStor 2200 V3/2600 V3 to host LUNs created on the EMC VNX5500.
    1. Create a storage pool for eDevLUNs.

      Navigation path: Choose Provisioning > Storage Pool > Create.

    2. Initiate automatic LUN scanning.

      Navigation path: Choose Data Protection > Remote Device, select the remote device whose Name is EMC VNX5500 and Device Type is Heterogeneity, and click Automatic Scan in the navigation bar in the upper part.

    3. Create eDevLUNs.

      Navigation path: Choose Data Protection > Remote Device, select the remote device whose Name is EMC VNX5500 and Device Type is Heterogeneity, and choose Remote LUN > Create eDevLUN in the navigation bar in the lower part.

    4. Set up a mapping relationship between the Oracle hosts and eDevLUN_VNX1 as well as between the Oracle hosts and eDevLUN_VNX2.

      Perform the following operations:

      1. Create a host.

        Navigation path: Choose Provisioning > Host > Host > Create > Manually Create.

      2. Create a host group.

        Navigation path: Choose Provisioning > Host > Host Group > Create.

      3. Create a LUN group.

        Navigation path: Choose Provisioning > LUN > LUN Group > Create.



      4. Create a mapping view.

        Navigation path: Choose Provisioning > Mapping View > Create.



    5. Run the cfgmgr command on each of the Oracle hosts to scan for the mapped logical disks.
