Troubleshooting Basic HyperSwap sessions

Basic HyperSwap® is composed of three components: Copy Services Manager, System Data Mover (SDM), and IOS. Depending on the type of error, the Copy Services Manager log package and additional information might be necessary to diagnose Basic HyperSwap problems. To increase the likelihood of collecting enough problem determination data the first time a Basic HyperSwap problem occurs, the following should be done:

• Package the log files on the management server using the Copy Services Manager GUI.
• Collect SYSLOGs from all systems in the sysplex.
• Take dumps from all systems in the sysplex and include the HyperSwap API Address Space, the HyperSwap Management Address Space, and the IOS Address Space in the dumps.
• Issue the following commands on the primary and secondary storage systems to confirm the state of the systems as well as the current replication direction.

  D U,,,devnum,nn

  View the storage system status to see whether devices are boxed, online, or offline.

  D M=DEV(devnum)

  View details on a single volume; also shows a range of volumes, if a range is specified as devnum.

  D HS,STATUS

  View the Basic HyperSwap status.

  D HS,CONFIG(DETAIL,ALL)
