Hello Michael,
We are actually migrating z10(2097-E26) to zEC12( 2827-H43)
Mainframe.
So, I have updated the Machine type model as well in HCD along with new
LPAR defination.
Initial I had 4 LPAR but I have added 6 more new LPAR. Also below are my
defination of FCP chip id .
CHPID PATH=(CSS(0),50),SHARED,
*
PARTITION=((TEST1,TEST3,TEST4,TEST),(=)), *
TYPE=FCP
CHPID PATH=(CSS(0),51),SHARED, *
PARTITION=((TEST1,TEST3,TEST4,TEST),(=)), *
TYPE=FCP
etc...
CNTLUNIT CUNUMBR=6400,PATH=((CSS(0),50)),UNIT=FCP
IODEVICE ADDRESS=(6400,120),CUNUMBR=(6400),UNIT=FCP
CNTLUNIT CUNUMBR=6500,PATH=((CSS(0),51)),UNIT=FCP
IODEVICE ADDRESS=(6500,120),CUNUMBR=(6500),UNIT=FCP
etc..
Can you please suggest what changes I should make to add these FCP chip
id's in the access list of these new 6 LPAR's.
