Installation Process

PARM Customization

The statements described in this section are all described in the Cisco IOS for S/390 Customization Guide. That document is the definitive source of information for these members. These members are all shipped with the product.

Note PARM members are now under SMP/E control. In order to avoid possible overwrite by future PTFs, copy your 00 members to 01 or another suffix of your choice. You must also make the appropriate adjustments in members STARTxx, DNRCFGxx, and TCPCFGxx which point to other PARM members.

Some of the Cisco IOS for S/390 release 1.0 members have been changed or deleted and many parameters have been relocated to different members in Cisco IOS for S/390 release 2.0. We recommend that you select your Cisco IOS for S/390 release 2.0 members and then split screen to browse your Cisco IOS for S/390 release 1.0 members in order to transfer the appropriate parameters to the correct Cisco IOS for S/390 release 2.0 members. Use the chart at the beginning of this document to see where parameters were in Cisco IOS for S/390 release 1.0.

APPCFGxx: Verify that the service statements that were in member ACPCFGxx in Cisco IOS for S/390 release 1.0 are now in APPCFGxx.

APPLUPxx: The LUPOOL statement has a new ALLOCATE parameter:

ALLOCATE( FIRST ) Directs LUPOOL to allocate the first available LU.

Due to performance considerations this is the preferred startup option

This is the default.

ALLOCATE( NEXT ) Directs LUPOOL to allocate LUs in sequential order.

This option adds flexibility in an error LU situation. This option should be specified at a site only at the direction of TAC personnel when the VTAM network is not working properly.

DNRxxxxx: In general, you can transfer or copy these members from the Cisco IOS for S/390 release

1.0PARM library to the Cisco IOS for S/390 release 2.0 PARM library. However, be sure to verify accuracy and validity of the parameters and their placement.

DNRALCxx: Users running in a multihomed environment must place entries in the DNRALCxx member for all non-loopback LNIs to allow domain name resolution to occur. If only one is defined, expect the following message:

T01CF150E APP configuration error: invalid SUBSYS Name subsysname

Processing continues after the message displays.

DNRCFG01: Replace NAMESERVER(NONE) with NAMESERVER(DNRNSC01). You will be customizing this member later.

DNRNSC01: Complete the lines requesting that you “set server for your domain.”

IJTCFGxx: The existing Cisco IOS for S/390 release 1.0 authorization keys work for Cisco IOS for S/390 release 2.0 if you use the same CPU. CPU serial numbers, processor status, and other information can be obtained via execution of the MVS command D M=CPU.

STARTxx: To aid in diagnosis, insert the following statement on the first line of the STARTxx member:

MODIFY TRACE ON SIZE(256)
