Can IASP data be saved in Restricted system state?

If the system is in restricted state, it is possible to save the security data by using the command SAVSECDTA ASPDEV(*ALLAVL). This command will save the private authorities for all available IASPs.

To save the IASP at V5R2, it must be in AVAILABLE or ACTIVE status. The IASP status changes from AVAILABLE to ACTIVE when all subsystems are closed because the jobs that service the ASP are under QSYSWRK.

Starting from V5R3, it is possible to save the IASP only if it is in AVAILABLE status. This does not mean that the security data cannot be saved if the system is in restricted status because if the IASP is AVAILABLE before the closure of all subsystems, the status will not be changed to ACTIVE any more. In fact, the jobs that service the IASP are system jobs that are no longer under subsystem QSYSWRK, so they will not be ended any more when going to restricted state.
