Chapter 7. FLEX-ES definitions/operation

This chapter is intended as a brief tutorial for FLEX-ES definitions and commands.

You must refer to the full FLEX-ES documentation for complete details.

This chapter reviews a selected subset of the FLEX-ES parameters needed to define

emulated S/390 systems and their resources. The formal FLEX-ES documentation should be

reviewed for additional information, more emulated devices, and many other parameters. The

last section also discusses basic CLI commands that can be used at the flexes prompt.

The illustrations in this section are only for discussion and are not intended to represent a

working system.

FLEX-ES definitions must be

exactly correct or they will not work. Take special care with

colons, parentheses, and hex numbers.

7.1 System definitions

System definitions are usually something like this:

system S14A:

memsize(262144) # K Central Storage = 256 MB

cachesize(4096) #

essize(64) # M Expanded Storage = 64 MB

instset(esa) # Use “z” for ALS3 (64-bit) mode

tracesize(512)

feature lpar # Normally only for VM

cpu(0) dedicated # Single Pentium, dedicated

channel(0) local

channel(1) local

channel(2) local

channel(3) local

cu devad(0x00C,3) path(0) resource(R14A2821) # 2450R, 2540P, 1403

cu devad(0x560,1) path(0) resource(R14A3480) # tape drive (4mm)

cu devad(0x700,16) path(1) resource(R14A3174) # 3270 terminals

cu devad(0xA80,12) path(2) resource(R14A3990) # 3390 disks

cu devad(0xE20,2) path(3) resource(R14A3088) # CTCs for TCP/IP

end S14A
