Hi Don, What you have looks fine, though I have a few minor points to offer:
- Newer IBM DASD contains an Access Control List that identifies which HOST WWPNs (associated with the FCP CHPID) can access which LUNs within the box, so you won't always be able to get to every LUN in the box as you have described below. - Newer processors (I'm thinking z9 here) can have a unique WWPN per FCP subchannel, such that the aforementioned ACL can restrict LUNs to a particular guest rather than everyone using the same CHPID. See http://www.redbooks.ibm.com/abstracts/redp4125.html for more information on this feature. - The LOADDEV command also exists as a CP directory statement. So you could bypass the IPL of CMS by putting the LOADDEV information in the directory entry for your Linux guest, and have it IPL the FCP subchannel instead of 190. What you have will work, but you don't need to fire up CMS to get there. Hope this helps you out some. Good luck!
