Multiple Lpars Connected Through Multiple Vlans - IBM z13s Technical Manual

Note: On the IOCDS statement, the VCHID is defined as 7E1. In Figure D-17 on
page 496, the ISM network "PNET 1" is referenced by the IOCDS VCHID statement. ISM
(just like IQD) doesn't use physical cards or card slots (PCHID), but only logical (firmware)
instances that are defined as VCHIDs in IOCDS.
Example D-3 shows a sample IOCP FUNCTION configuration that defines ISM adapters
shared between LPSRs and multiple VLANs on the same CPC as shown in Figure D-18.
This OS (LP2 & LP5) have
access to 2 VLANs on the
same ISM network; requires a
single ISM FID (VF)

Workloads can be logically isolated on separate ISM VCHIDs. Alternatively, workloads can be
isolated by exploiting VLANs. The ISM VLAN definitions are inherited from the associated IP
network (OSA or HiperSockets).
