3. If the $SYSTEM, DSM/SCM, and Archive volumes are not listed in the display,
contact your service provider.
4. Verify that the primary path, backup paths, mirror path, and mirror backup path are
started for the mirrored $SYSTEM volume. If any paths are stopped, start them.
5. Verify that the primary path and backup path are started for the $DSMSCM volume
and the $AUDIT volume. If any paths are stopped, start them.
Check the Swap File Configuration
You must ensure that you have configured kernel-managed swap files of sufficient size
for all your system and application software processes. The optimal amount of swap
space varies, depending on the configuration of your system. The default swap files
can allocate up to 128 megabytes (MB) per processor. However, many processes and
applications require more swap space. Inadequate swap space can cause process-
creation errors, abended processes, and halts.
To check the size of the configured swap files for each processor:
1. At a TACL prompt, start NSKCOM and enter an INFO SWAPFILE * command.
For example:
3> nskcom info swapfile *
