MPTS adapter numbers and slot positions:
You can specify adapter slot/device identifier in MPTS configuration.
Relation of physical slot numbers and slot/device identifiers
is given in MP3000 installation manual (SY24-6154-02), page 5-3 and
in redbook Multiprise 3000 Basic Emulated I/O Definitions
(SG24-5669-00), page 38:
Slot slot identifier
LG09 0064
LG10 0065
LG11 0066
LG12 0067
LG17/18 000B
If slot is not specified in MPTS and you have multiple ethernet
or multiple tokenring adapters, then ethernet adapters are assigned
from bottom to top, tokenring adapters are assigned from top to bottom.
The same device driver "IBM 10/100 Ethernet PCI adapter" can be used
for both built-in ethernet adapter and additional ethernet adapters.
(You should use current device driver; old version may not recognize
built-in adapter). Each occurrence of ethenet driver in config.sys
assigns the next ethernet adapter and displays (at boot time) slot
identifiers of all ethernet cards recognized and what slot is assigned.
This order of adapters is described in MP3000 Service guide
(SY24-6155-02), page 2-10 and
MP3000 Installation manual (SY24-6154-02), pages 6-35, 6-40.
If ethernet adapter is to be used by mainframe TCPIP, then
specify 'D' as 'type of Ethernet driver support' in
'properties of IBM IEEE 802.2'
Device map
Run awscfg, put cursor on device definition or driver name LCS3172,
press F1, read help (D:\P390\LCS3172.DOC)
The help file contains example of TCPIP definition and explanation of
adapter numbering.
Device numbers are not related to network adapters. You should use only
one device pair (even,odd) to access all network adapters. You need
more than one device pair, if devices are used by multiple instances
of TCPIP, e.g. more LPARs. The same adapter cannot be used by
multiple instances of TCPIP at the same time.
PROFILE.TCPIP
Adapter number specified in PROFILE.TCPIP is equal to sequential number
(beginning with 0) of those network adapters in MPTS, that have
protocol IEEE 802.2 specified.
Example:
2 LPARs, we need 3 Ethernet adapters.
Use adapter on SBC (single board computer - slot LG17/18) for TCPIP OS/2
and 2 additional adapters for 2 LPARs - in slots LG11, LG12.
MPTS:
adapter
0 Ethernet adapter (slot LG17)
protocol TCPIP (used by TCPIP OS/2)
protocol IEEE 802.2 (may be used by LPAR1 and LPAR2 SNA and
OS/2 SNA, specify type='I')
1 Ethernet adapter (slot LG12)
protocol IEEE 802.2 (used by TCPIP LPAR1, specify type='D')
2 Ethernet adapter (slot LG11)
protocol IEEE 802.2 (used by TCPIP LPAR2, specify type='D')

00CD 3088 LCS3172 Write channel LPAR1
00CE 3088 LCS3172 Read channel LPAR2
00CF 3088 LCS3172 Write channel LPAR2
IOCP:
CNTLUNIT CUNUMBR=FCCC,PATH=(FC),UNIT=3172,UNITADD=((CC,1))
IODEVICE ADDRESS=(05CC,1),CUNUMBR=(FCCC),UNIT=3172, X
UNITADD=CC,PART=PAR1
CNTLUNIT CUNUMBR=FCCD,PATH=(FC),UNIT=3172,UNITADD=((CD,1))
IODEVICE ADDRESS=(05CD,1),CUNUMBR=(FCCD),UNIT=3172, X
UNITADD=CD,PART=PAR1
CNTLUNIT CUNUMBR=FCCE,PATH=(FC),UNIT=3172,UNITADD=((CE,1))
IODEVICE ADDRESS=(05CE,1),CUNUMBR=(FCCE),UNIT=3172, X
UNITADD=CE,PART=PAR2
CNTLUNIT CUNUMBR=FCCF,PATH=(FC),UNIT=3172,UNITADD=((CF,1))
IODEVICE ADDRESS=(05CF,1),CUNUMBR=(FCCF),UNIT=3172, X
UNITADD=CF,PART=PAR2
PROFILE.TCPIP, LPAR PAR1:
DEVICE LCS1 LCS 5CC
LINK ETH1 ETHERNET 1 LCS1
PROFILE.TCPIP, LPAR PAR2:
DEVICE LCS2 LCS 5CE
LINK ETH2 ETHERNET 2 LCS2
If 2 ethernet cards are used in the same LPAR, then 1 device pair
is sufficient:
DEVICE LCS1 LCS 5CC
LINK ETH1 ETHERNET 1 LCS1
LINK ETH2 ETHERNET 2 LCS1
