22.4. Configuring IPL from a SCSI Device

Anaconda (the installation program) supports the direct installation to SCSI devices. This section includes information on how to IPL from a SCSI device within z/VM.

22.4.1. IPL the SCSI Disk

To IPL the SCSI disk, we provide the WWPN and LUN to the machine loader using the SET LOADDEV command.
#cp set loaddev portname 50050763 00c18154 lun 57190000 00000000
Ready; T=0.01/0.01 15:47:53
q loaddev
PORTNAME 50050763 00C18154    LUN  57190000 00000000    BOOTPROG 0
BR_LBA   00000000 00000000
Ready; T=0.01/0.01 15:47:56
IPL the SCSI disk using the FCP device defined to the guest.
