I received the following question this morning :
We are busy installing a SL8500 ATL with STK 10000 drives
TST1 *Control Unit List * Row 9 of 161
Command ===> _______________________________________________ Scroll ===>
CSR
Select one or more control units, then press Enter. To add, use F11.
---#---
/ CU Type + CUADD CSS MC Serial-# + Description
_ 0600 3590 *0* 2 __________ STK T10K Cartridge - Driver 33
_ 0610 3590 __________ STK T10K Cartridges
_ 0620 3590 *2* 2 __________ STK T10K Cartridge - Drive 35
_ 0630 3590 *3* 2 __________ STK T10K Cartridge - Drive 36
_ 0640 3590 *4* 2 __________ STK T10K Cartridge - Drive 49
_ 0650 3590 *5* 2 __________ STK T10K Cartridge - Drive 50
_ 0660 3590 * 6* 2 __________ STK T10K Cartridge - Drive 52
Only *0600* goes online (CUADD is 0) but if we use a Gen with no CUADD
numbers, then all of the drives are online.
According to my understanding, we need a CUADD for every controller on
the FICON
If we change the CUADD of 0600 to 1, then it also does not work.
We connect the FICON from the CPU, to a switch and all the control units
are on the other side of the switch
