Depending on what's wrong, you can just use the IPL option on XAUTOLOG to change to a different local port. For problems in the SAN, you'll need to XAUTOLOG with NOIPL and use SEND or FOR to orchestrate the IPL. One could wish for IPL vdev1 vdev2 LOADDEV PORT port1 LOADDEV PORT port2 LOADDEV LUN 4000400700000000? Such that CP would try vdev1+port1, vdev1+port2, vdev2+port1, and finally vdev2+port2, looking for a successful boot. I might be tempted to allow multiple LUNs, too. SET LOADDEV would allow multiple entries, too. Alternatively, provide for virtual load profiles: * LOADPROFILE 1 IPL vdev1 LOADDEV PORT port1 LOADDEV LUN 4000400700000000? * LOADPROFILE 2 IPL vdev2 LOADDEV PORT port2 LOADDEV LUN 4000400700000000? And CP would try them in numerical order. Possibly allow the profile number to be specified on XAUTOLOG. And, ooh, I know!, a new POWERON command that does what XAUTOLOG SYNCH does, but provides any of the boot loader or "3-card loader" messages back to the command issuer to assist in diagnosis. And maybe look at more symbolics in the directory (user environment variable references, perhaps). If I keep typing it will get even more complex and wonderful, so I'll stop here. :-) Alan Altmark Senior Managing z/VM and Linux Consultant IBM Systems Lab Services IBM Z Delivery Practice ibm.com/systems/services/labservices office: 607.429.3323 mobile; 607.321.7556 [email protected] IBM Endicott ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www2.marist.edu/htbin/wlvindex?LINUX-390
