IP Mirroring A This appendix provides information to help you implement and support IP mirroring at the customer site. For an overview of IP, refer to “Managing IP Mirrors” in the HP OpenView Continuous Access Storage Appliance System Administrator’s Guide.
PAGE 128
IP Mirroring Managing worker threads This section describes worker threads and how to use them for IP mirroring requests. It describes the following topics: ■ Worker threads overview ■ Adjusting the number of worker threads ■ Using worker threads for many-to-one IP mirroring Worker threads overview The appliance software uses worker threads to process I/O requests.
PAGE 129
IP Mirroring Using worker threads for many-to-one IP mirroring When implementing many-to-one IP mirroring, you must reduce the number of IP mirroring worker threads; otherwise, IP mirroring will not function properly. The total number of IP mirroring worker threads for all source appliances cannot exceed 200. When calculating this number, count by appliance, not appliance node because only one appliance node can process IP mirroring requests at a time.
PAGE 130
IP Mirroring Processing synchronous IP mirroring requests This section describes how the appliance software processes synchronous IP mirroring requests. It describes the following topics: ■ Synchronous IP mirroring process ■ IP mirroring performance Synchronous IP mirroring process Processing synchronous IP mirroring requests involves the following steps (Figure 28): 1. The host sends a request to the local LUN. 2.
PAGE 131
IP Mirroring IP mirroring performance In Figure 28, T0 indicates the time at which the host sends I/O to the local LUN, initiating the IP mirroring request. T1 indicates the time at which the host receives a completion message from the local LUN, ending the IP mirroring request. T0 and T1 are measured in milliseconds. For example, T0 is 10:35:02:15 and T1 is 10:35:03:20. To calculate IP mirroring performance, subtract T0 from T1.
PAGE 132
IP Mirroring Processing asynchronous IP mirroring requests Processing asynchronous IP mirroring requests involves the following steps (Figure 29): 1. The host sends a request to the local LUN. 2. A worker thread receives the request on the local LUN and completes the request. 3. Another worker thread adds the replication request data to the asynchronous IP mirroring (AIPM) queue. 4. The first worker thread waits for the second worker thread to confirm that the request has been added to the AIPM queue.
PAGE 133
IP Mirroring Understanding resynchronization This section describes the differences between resynchronizing synchronous and asynchronous IP mirrors. It describes the following topics: ■ Synchronous IP mirrors ■ Asynchronous IP mirrors ■ Common resynchronization issues Synchronous IP mirrors If the network goes down, synchronous IP mirroring (and all other network activity) stops. During this down time, the appliance software tracks replication requests in the source LUN’s journal file.
PAGE 134
IP Mirroring Common resynchronization issues A description of common resynchronization issues follows: ■ After you power off the resynchronizing node, synchronous IP mirrors disconnect. Temporarily disconnecting the IP mirrors starts resynchronization on the new resynchronizing node, (the peer node that is working). Resynchronizing ensures that the data on the source and target LUNs of the mirrors is current.
PAGE 135
IP Mirroring Troubleshooting IP mirroring A description of common IP mirroring situations follows: ■ I/O stops on the hosts after disconnecting the InterLink and MirrorLink. If you disconnect the InterLink and MirrorLink, the appliance loses all connectivity to the mirror site and enters arbitration. The appliance cannot enter arbitration until all I/O times out. To prevent I/O from timing out, increase the value of the I/O time–out parameter (for example, 10 minutes).

Service Messages Setting node logging levels The health monitor issues SNMP requests to the ProLiant insight management agents installed on the appliance nodes. The status information gathered by the health monitor displays in the status info section of the hp OV CASA Console window (See Navigating the CASA console on page 24 for more information.) The health monitor uses a logger to assist with troubleshooting. You can modify the logging levels using the logging_level parameter contained in the logger.
