2. Verify that each processor in the system has a configured swap file of at least 256
MB in the minimum for any G-series system. Depending on how many processes
you have, your system configuration might require more swap space.
For each processor, configure at least twice as much swap space as there is
memory. For example, if you have 256 MB of memory for each processor,
configure 512 MB of swap space. If you have 1 GB or 2 GB memory per processor,
you might need additional swap space.
3. From NSKCOM, perform a STATUS to verify which swap files are in use. For
example:
4> nskcom status swapfile *

Note. Configure swap files if necessary. See the Kernel-Managed Swap Facility
(KMSF) Manual for information about how to configure swap files and for guidelines
about how much swap space should be allocated per processor.
