SAN boot support on IBM Z hosts running Linux
You can perform an initial program load (IPL) from a SCSI LUN. However, be aware that the boot can fail if there is no multipath support during the boot process.
For more information about using IPL processes with IBM Z hosts, see the latest edition of How to use FC-attached SCSI devices with Linux on Z. You can access this publication on the IBM® developerWorks® website at IBM Developerworks Linux® on Z website.
