The short answer is that what you want to do is very possible. We've been
running with similar configurations for many years through various hardware
combinations and LPAR distribution. Our specific IEASYMxx members would
probably not fit your particular needs and are overly complicated anyway. I can
offer a few suggestions.
1. In addition to SYM, you also want two LOADxx members. When we IPL in
'normal' mode, we use LOAD00. When we IPL in DR mode, we use LOADDR. The choice
is determined by the load parm value in the IPL profile: '00' for normal
profile, 'DR' for DR mode profile. That suffix is appended to 'LOAD' to select
the appropriate member in the IPLPARM library.
2. The primary difference between LOAD00 and LOADDR is the concatenation list
for IEASYMxx. Within each concatenation, system symbols are set according to
the environment being IPLed. This accounts for, among other values, different
CTC addresses, gazinta and gazouta, among LPARs in normal vs. DR configuration.
3. IEASYMxx contains statements like these, which are specified for each
hardware-LPAR combination, normal or DR mode
SYSDEF HWNAME(box-1) LPARNAME(LPAR-1) /* FOR THIS LPAR-PROCESSOR */
SYSNAME(sysname-1) /* USE THIS SYSNAME */
SYMDEF(&CTCPID#1='i-xxx,i-yyy') /* SET INPUT ADDRESS LIST */
SYMDEF(&CTCPOD#1='o-xxx,o-yyy') /* SET OUTPUT ADDRESS LIST */
4. Here are some sample statements from COUPLExx.
COUPLE
SYSPLEX(SYSPLEX&OURPLXID) /* Symbol set in IEASYSxx */
PCOUPLE(SYS1.COUPLE.SYSPLEX1)
ACOUPLE(SYS1.COUPLE.SYSPLEX2)
PATHIN /* BACKUP CTC FOR CF */
DEVICE(&CTCPID#1,&CTCPID#2,&CTCPID#3) /* Symbol strings set in
IEASYSxx */
PATHOUT /* BACKUP CTC FOR CF */
DEVICE(&CTCPOD#1,&CTCPOD#2,&CTCPOD#3) /* Symbol strings set in
IEASYSxx */
CLASS(DEFSMALL)
You're on the right track. You should be able to completely initialize either
environment by changing only the HMC load parm, which really means choosing--by
name--between a 'normal' profile and the corresponding 'DR' profile.
If you have not done so, install the SYSPARM dialog from SYS1.SAMPLIB(SPPINST).
It is immensely helpful in testing system symbol settings.

Subject: IEASYMxx: How is possible define more than one LPARNAME at same time
in SYSDEF?
Hi, all
Is possible define more than one LPARNAME at same time in the parameter SYSDEF
in the IEASYMxx member?
I try to explain our problem:
We have two z196 in different buildings. The definition is the following:
z196-1:
with the following LPARs: PROD1, PROD2 and TEST1 and
z196-2:
with the following LPARs: PROD3, PROD4 and TEST2
The problem that we have is that in the movements of FDR (Full Disaster
Recovery) some Partitions change to the other building, except the Partitions
TEST-1 and TEST-2 and the channel addresses for CTC (FICON) are different
according to definition in the IODF for each Building (z196-1 or z196-2).
That is, after FDR final test the situation is as follows:
z196-1:
has the following LPARs: PROD3, PROD4 and TEST1 and
z196-2:
has the following LPARs: PROD1, PROD2 and TEST2
The LPARs: TEST1 and TEST2 never change your location, however the channel
addresses for CTCs are now different to connect with the new partitions that
have been moved to the z196-1 or z196-2.
Q.1) Can be possible to use a definition of Symbols like this..?
SYSDEF HWNAME (z196-1) LPARNAME (PROD1) LPARNAME (PROD2) LPARNAME (TEST1)
SYMDEF (&CTCP1T1 = '662E') / * CTC BETWEEN PROD1 - TEST1 * /
.....................................
SYMDEF (&CTCP2T1 = '6822') / * CTC BETWEEN PROD2 - TEST1 * /
Q.2) It would be possible to use combinations (ie. as in REXX) using special
characters like '&' (AND) '|' (OR) in the IEASYM..?
SYSDEF HWNAME (z196-1) & LPARNAME (PROD1) & LPARNAME (PROD2) LPARNAME (TEST1)
for example, if we use the following combination:
SYSDEF HWNAME (z196-1) LPARNAME (TEST1)
SYMDEF (&CTCP1T1 = '662E') / * CTC BETWEEN PROD1 - TEST1 * /
it does not work because the channel addresses for CTC of TEST1 are different
when after FDR has to connect with the new LPARs: PROD3 and PROD4 (and in this
case, the Partition PROD1 doesn't exist in the machine z196-1).
Q.3) Then. How could define in the same configuration of the IEASYM member to
before and after of the FDR movement..?
It is important to mention that the channel addresses for CTC are different in
a z196-1 with respect to the channel addresses for CTC in the other z196-2
(different building). There are not have a specific IEASYSxx and IEASYMxx
settings for FDR because we only use two LOADxx members where they have defined
in the IODF the Partitions directly with a matrix for the CHPIDs for one
Building (z196-1) and other different matrix (also with different CHPIDs) for
the other Building (z196-2).
Q.4) Please, someone have any idea about it..?
No matter how complex can become the definition of IEASYMxx if with that
definition a solution is found.
Honestly, I'm confused because I do not find a way to merge two partitions that
always move to another machine, with a partition (TEST1) that never moves from
that machine (z196-1) and vice versa (TEST2 never moves from z196-2).
Any ideas are welcome.
