Configuring HP MA and EMA systems

The HP MA and EMA systems provide functions that are compatible with the SAN Volume Controller.

1. Verify that the front panel of the SAN Volume Controller 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 command and SHOW OTHER command to verify the following:
   1. Ensure that the system firmware is at a supported level. See the following Web site for the latest firmware support:

      www.ibm.com/storage/support/2145.

   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 the following:
   1. Ensure that none of the LUNs are TRANSPORTABLE.
   2. Ensure that all LUNs are configured. For example, the LUNs 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, there should be no orange lights on any disks in the system.
7. Issue the SHOW UNITS FULL command to verify the following:
   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 SAN Volume Controller 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 SAN Volume Controller 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 SAN Volume Controller 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. The following is an example of the output that is displayed: PORT_1_TOPOLOGY=FABRIC.
12. Issue the SHOW CONNECTIONS FULL command to verify that the new connections have been created for each SAN Volume Controller 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 the following steps from the SAN Volume Controller command-line interface (CLI):
    1. Issue the svctask detectmdisk CLI command to discover the controller.
    2. Issue the svcinfo lscontroller CLI command to verify that the two HSG80 serial numbers appear under the ctrl s/n.
    3. Issue the svcinfo lsmdisk CLI command to verify that the additional MDisks that correspond to the UNITS shown in the HP MA or EMA system.
