Configuring HP MA and EMA systems

You can configure the HP MA and EMA systems to provide functions that are compatible with the system.

This task assumes that the system is not in use.

Note: When you configure the to work with an HP MA or EMA, you must not exceed the limit of 96 process logins.

Complete these steps to enable support of an HP MA or EMA system.

  1. Verify that the system is clear of errors.
  2. Ensure that the HP StorageWorks Operator Control Panel (OCP) on each system is clear of errors. The Operator Control Panel consists of seven green LEDs at the rear of each HSG80 controller.
  3. Ensure that you can use an HP StorageWorks command-line interface (CLI) to configure the HSG80 controllers.
  4. Issue the SHOW THIS and SHOW OTHER commands to verify these items:
    1. Ensure that the system firmware is at a supported level. Refer to the following web site for the latest firmware support:

      https://datacentersupport.lenovo.com/.

    2. Ensure that the controllers are configured for MULTIBUS FAILOVER with each other.
    3. Ensure that the controllers are running in SCSI-3 mode.
    4. Ensure that MIRRORED_CACHE is enabled.
    5. Ensure that the Host Connection Table is not locked.
  5. Issue the SHOW DEVICES FULL command to verify these items:
    1. Ensure that none of the LUNs are TRANSPORTABLE.
    2. Ensure that all LUNs are configured.; that is, the LUNs must report their serial numbers and TRANSFER_RATE_REQUESTED correctly.
  6. Issue the SHOW FAILEDSET command to verify that there are no failing disks.
    Note: To verify, no orange lights should be lit on any disks in the system .
  7. Issue the SHOW UNITS FULL command to verify these items:
    1. Ensure that all LUNs are set to RUN and NOWRITEPROTECT.
    2. Ensure that all LUNs are ONLINE to either THIS or OTHER controller.
    3. Ensure that all LUNs that are to be made available to the system have ALL access.
    4. Ensure that all LUNs do not specify Host Based Logging.
  8. Issue the SHOW CONNECTIONS FULL command to verify that you have enough spare entries for all combinations of system ports and HP MA or EMA ports.
  9. Connect up to four Fibre Channel cables between the Fibre Channel switches and the HP MA or EMA system.
  10. Ensure that the Fibre Channel switches are zoned so that the system and the HP MA or EMA system are in a zone.
  11. Issue the SHOW THIS command and SHOW OTHER command to verify that each connected port is running. This example is similar to the output that is displayed: PORT_1_TOPOLOGY=FABRIC.
  12. Issue the SHOW CONNECTIONS FULL command to verify that the new connections were created for each system port and HP MA or EMA port combination.
  13. Verify that No rejected hosts is displayed at the end of the SHOW CONNECTIONS output.
  14. Perform these steps from the system command-line interface (CLI):
    1. Issue the detectmdisk CLI command to discover the storage system.
    2. Issue the lscontroller CLI command to verify that the two serial numbers of each HSG80 controller in the storage system appear under the ctrl_s/n (controller serial number) column in the output. The serial numbers appear as a single concatenated string.
    3. Issue the lsmdisk CLI command to verify that the additional MDisks that correspond to the UNITS shown in the HP MA or EMA system.

You can now use the system CLI commands to create a storage pool. You can also create and map volumes from these storage pools. Check the front panel of the system to ensure that there are no errors. After the host has reloaded the Fibre Channel driver, you can perform I/O to the volumes. For more imformation, see the host attachment information.
