If you use logical partition (LPAR) mode provided by the Processor Resource/System Manager (PR/SM), you may have additional considerations when performing these tasks:

• Entering keys
• Displaying hardware status
• Using the public key algorithm
• Using a TKE Workstation

These additional considerations depend on your processor hardware. For example, LPAR mode permits you to have multiple logical partitions and each logical partition (LP) can have access to the crypto CP for key entry. Therefore, at any given time, multiple LPs can perform key entry procedures.

This appendix gives some basic information on using ICSF in LPAR mode. For more detailed information on configuring and running in LPAR mode, refer to the zSeries PR/SM Planning Guide and the S/390 Hardware Management Console Guide.
