98 The Virtualization Cookbook for Red Hat Enterprise Linux 5.2
NICDEF statement in the USER DIRECT file), and that two VDISKs have been created at
virtual addresses 300 and 301 (using the SWAPGEN EXEC called from the PROFILE EXEC):
LOGON LNXINST
00: NIC 0600 is created; devices 0600-0602 defined
00: z/VM Version 5 Release 3.0, Service Level 0702 (64-bit),
00: built on IBM Virtualization Technology
00: There is no logmsg data
00: FILES: NO RDR, NO PRT, NO PUN

DIAG swap disk defined at virtual address 300 (64989 4K pages of swap space)
DIAG swap disk defined at virtual address 301 (129981 4K pages of swap space)
2. You are prompted to IPL Linux, but because you have not installed Linux yet, reply n:
Do you want to IPL Linux from minidisk 100? y/n
==> n
3. Before you install Linux, it is useful to verify the resources. Verify that you have DASD
(minidisks) at virtual addresses 100-104 and 300-301 with the QUERY VIRTUAL command
(other Linux IDs without class B privilege will just use the QUERY command):
==> q v 100-104
00: DASD 0100 3390 MMD856 R/W 3338 CYL ON DASD AD24 SUBCHANNEL = 0002
00: DASD 0101 3390 MMD857 R/W 3338 CYL ON DASD AD25 SUBCHANNEL = 0003
00: DASD 0102 3390 MMD952 R/W 3338 CYL ON DASD AD26 SUBCHANNEL = 0004
00: DASD 0103 3390 MMD953 R/W 3338 CYL ON DASD AD27 SUBCHANNEL = 0005
00: DASD 0104 3390 MMD954 R/W 3338 CYL ON DASD AE22 SUBCHANNEL = 0006
==> q v 300-301
00: DASD 0300 9336 (VDSK) R/W 524288 BLK ON DASD VDSK SUBCHANNEL = 0013
00: DASD 0301 9336 (VDSK) R/W 1048576 BLK ON DASD VDSK SUBCHANNEL = 0014
4. Verify that you have a virtual OSA at addresses 600-602 by using the QUERY VIRTUAL OSA
command:
==> q v osa
00: OSA 0600 ON NIC 0600 UNIT 000 SUBCHANNEL = 0007
00: 0600 DEVTYPE OSA CHPID 0E OSD
00: 0600 QDIO-ELIGIBLE QIOASSIST-ELIGIBLE
00: OSA 0601 ON NIC 0600 UNIT 001 SUBCHANNEL = 0008
00: 0601 DEVTYPE OSA CHPID 0E OSD
00: 0601 QDIO-ELIGIBLE QIOASSIST-ELIGIBLE
00: OSA 0602 ON NIC 0600 UNIT 002 SUBCHANNEL = 0009
00: 0602 DEVTYPE OSA CHPID 0E OSD
00: 0602 QDIO-ELIGIBLE QIOASSIST-ELIGIBLE
5. Use the QUERY VIRTUAL STORAGE command to show that you have a 256 MB machine:
==> q v stor
00: STORAGE = 256M
6. This is adequate memory to run a RHEL 5.2 Linux image. However, it is often too small in
which to install Linux. Temporarily modify the storage up to 512 MB with the DEFINE STORAGE
command. Then IPL CMS and again reply n to the question of IPLing Linux:
==> def stor 512m
00: STORAGE = 512M
00: Storage cleared - system reset.
==> ipl cms
