You can perform an IPL of an LPAR from a SCSI disk.
Follow these steps to IPL an LPAR from a SCSI disk:
Figure 2 shows the boot messages.
The kernel parameters show that the root file system of this Linux instance is on a SCSI disk (/dev/sda1). Production systems should not use /dev/sda1 as a root device, but use multi-pathing overlying the SCSI devices. See your distribution's documentation for how to set up multi-pathing.
In Figure 1, noresume has been typed into the Operating system specific load parameters field. In Figure 2 this specification has been concatenated to the end of the existing boot parameters used by the boot configuration. This causes a regular boot process, even if the Linux instance had previously been suspended to a swap partition.
