Dresmond, you can solve all this questions only with changes into SYSTEM CONFIG.
>>> 1) SYSTEM CONFIG has System_Identifer_Default ZVMCS1, we want our DR
to
>>> be ZVMCS3
Include Serial Number of each CPU to differentiate. Example:
SYSTEM_IDENTIFIER_DEFAULT UNDEFND
SYSTEM_IDENTIFIER * %%1341 ZVMCS1
SYSTEM_IDENTIFIER * %%0D06 ZVMCS3
>>> 2) I see duplicate MAC addresses on OSA,,, I found the VMLAN MACPREFIX
>>> statement, but since it goes in SYSTEM CONFIG, that brings me back to
the
>>> first issue again.
After step 1, prefix each VMLAN card with the Sysid. Example:>>
ZVMCS1: VMLAN MACPREFIX 021341
ZVMCS3: VMLAN MACPREFIX 020D06
>>> 3) TCPIP profile needs a different IP address, maskl and Gateway at
our
>>> DR site.
After step 1, TCPIP will use first the "sysid" profile by default. So,
create two profiles TCPIP with different names:
ZVMCS1 TCPIP,
ZVMCS3 TCPIP,
When these files exist, PROFILE.TCPIP will not be used by default.
>>> 4) If we make any of the changes above on the DR system, they will get
>>> over-written because the DASD replicates constantly.
Make the changes on your base dasd before the replication. The two VM
images can use the same SYSTEM CONFIG.
There are other changes possible in this same line. Please, see the manual
VM System Planning for details.
Good luck.

z/VM issues after replicating DASD
to DR site

Hope this email finds you well... We are building zVM/Linux/CCL/IPTG to
replace 3746-900's... We IPL'd our DR site remotely yesterday and ran into
issues because we replicate mirror images of all DASD to DR site from
production site... When z/VM ipls, CP is using the production system and
some parameters don't work in DR... For example,
1) SYSTEM CONFIG has System_Identifer_Default ZVMCS1, we want our DR to
be ZVMCS3
2) I see duplicate MAC addresses on OSA,,, I found the VMLAN MACPREFIX
statement, but since it goes in SYSTEM CONFIG, that brings me back to the
first issue again.
3) TCPIP profile needs a different IP address, maskl and Gateway at our
DR site.
4) If we make any of the changes above on the DR system, they will get
over-written because the DASD replicates constantly.
Any guidance is greatly appreciated, thanks....
