These steps assume the user has experience configuring and managing an IBM® System Storage® DS8000® and has a functioning HyperSwap configuration running.
For more information about using an IBM System Storage DS8000 unit, see Copy Services in the IBM System Storage DS8000 Information Center pages.
Review Configuring DS8000 Full System HyperSwap or Configuring DS8000 HyperSwap with independent auxiliary storage pools (IASPs) in the IBM i Knowledge Center to set up the initial configurations.
About this task
Either the SYSBAS volumes or the IASP volumes of your high availability HyperSwap configuration might require additional storage capacity. If your established HyperSwap environment requires additional disk units for more capacity, complete the following procedure to add units to the system or an existing IASP in a HyperSwap environment:
Procedure
To add new disk units to the system, user, or independent ASP, pause Peer-to-Peer remote Copy (PPRC) with the pausepprc command on the DS800 using the DSCLI.
Stop replication with the Change HyperSwap Status (CHGHYSSTS) command.
If you are adding disk units to an IASP, enter: CHGHYSSTS OPTION(*STOP) ASPDEV(iasp-name). Supply the name of the IASP in iasp-name.
For adding capacity to the system or user ASP, substitute *SYSBAS for the name of the IASP: CHGHYSSTS OPTION(*STOP) ASPDEV(*SYSBAS).
Add the new units to the system, user, or independent ASP with the System Service Tools (STRSST) command. Consult Adding a disk unit or disk pool for details about how to use the System Service Tools.
Resume replication with the Change HyperSwap Status command (CHGHYSSTS). Enter the command: CHGHYSSTS OPTION(*START) ASPDEV(iasp-name/*SYSBAS) .
Results
The expanded storage in your HyperSwap environment on your IBM i partition is available for use.
