Connecting to a DSSI Subsystem 5-13
The node IDs for KFMSA-BA modules are factory set with both ports hav-
ing the node ID of 7. KFMSA-BA node IDs for single-host systems do not
have to be changed. For a dual-host system, the second host system’s
KFMSA-BA node ID must be set to 6. On a tri-host system, the third host
system’s KFMSA-BA node ID must be set to 5. On a quad-host system, the
fourth host system’s KFMSA-BA node ID must be set to 4.
If the second and third hosts have multi-host I/O panels (as shown in Fig-
ure 5-5), use the KFMSA-BA select knob to change the KFMSA-BA node
ID.
If required, set the DSSI node IDs for the ISEs using the switches on the
disk PIU.
NOTE: The new ISE node IDs are not in effect until each device is turned
off, then on (power-cycled). After power-cycling, the node IDs have
been changed at the ISE level.
In addition to the physical space requirements, the ISEs and operating
system generate additional parameters to communicate with the host: sys-
tem ID, node name, MSCP/TMSCP unit numbers, allocation class, and
force name.
