J06.06 Software Installation and Upgrade Guide

DSM/SCM Upgrade Issues/Interoperability SPR Requirements
If you are migrating from a J06.04 or earlier RVU to a J06.07 or later RVU, be aware that the
USERID attributes of all persistent processes configured under $ZZKRN might change from
SUPER.SUPER to NULL.NULL. If this occurs on a system where $SYSTEM is using FCDM disk
enclosures connected by FCSAs in IOAM enclosures, the system might halt when a system load to
the new RVU is attempted. To prevent this problem, you must install DSM/SCM SPR T6031H02^ACJ
or later on your system. See Hotstuff HS03058 for more information.
