082

Explanation
The system entering the sysplex is removed to prevent
sysplex data corruption.  The system being partitioned either requires
maintenance to be installed to be able to coexist with the other systems
in the sysplex, or a system already active in the sysplex requires
maintenance to be installed to be able to coexist with the failing
system. A reason code in register 15 explains the error: Code
Explanation
00
A pre V1R8 system without APAR OA10632 applied is attempting
to enter a sysplex that has a V1R8 system active in the sysplex. The
V1R8 system issues message IEA002I, and the pre-V1R8 system loads
wait state X'082'.
A V1R8 system is attempting to enter
a sysplex that has an active system in the sysplex that is pre-V1R8
and does not have APAR OA10632 applied. The V1R8 system issues message
IEA002I and loads wait state X'082'.
A pre V1R10 system
without APAR OA18204 applied is attempting to enter a sysplex that
has a V1R10 system active in the sysplex. The V1R10 system issues
message IEA002I, and the pre-V1R10 system loads wait state X'082'.
A
V1R10 system is attempting to enter a sysplex that has an active system
in the sysplex that is pre-V1R10 and does not have APAR OA18204 applied.
The V1R10 system issues message IEA002I and loads wait state X'082'.
A
V1R11 system or V1R9-V1R10 with APAR OA27222 applied is attempting
to enter a sysplex that has an active system in the sysplex that is
pre-V1R11 and does not have APAR OA24172 applied. The V1R11 system
issues message IEA002I and loads wait state X'082'.
A
pre-V1R11 system without APAR OA24172 applied is attempting to enter
a sysplex that has an active system in the sysplex that is V1R11 or
V1R9-V1R10 with OA27222 applied. The V1R11 system issues
message IEA002I and the pre-V1R11 system loads wait state X'082'.
A pre-V2R1 system without APAR OA36207 applied is attempting
to enter a sysplex that has an active system in the sysplex that is
V2R1 or pre-V2R1 with OA36207 applied. The V2R1 system issues message
IEA002I and the pre-V2R1 system loads wait state X'082

08
A z/OS® V1R11 or above system
or z/OS V1R9-V1R10 system with
APAR OA27222 applied is attempting to enter a sysplex with
at least one system that has a minimum required GRS version higher
than the GRS version of this system. This system waited 1 minute to
be removed from the sysplex, but was not removed, and subsequently
removed itself.

System action
The system entering the sysplex is partitioned
from the sysplex and wait state X'082' is loaded on that
system to prevent global sysplex data corruption.  
For reason
code X'00', message IEA002I is issued, either on the failing
system or on an active system in the sysplex, indicating which system
requires maintenance to be applied and the appropriate APAR to apply. 
For
reason code X'08', message IEA002I is issued on the failing
system, indicating that the system requires maintenance. The system
does not know the appropriate APAR to apply, so the text of the message
is IEA002I APAR UNKNOWN IS NOT INSTALLED.

System programmer response
Read the information regarding installation
of the appropriate APAR(s).
