LXFMT V2.1: LXFMT is a CMS utility that provides the functions of both the DASDFMT and FDASD Linux utilities. LXFMT can be used for ECKD and FBA devices. TBROWSE: TBROWSE is a CMS utility that allows you scan a real or virtual tape in a full screen browse like format. TAPSENSE: TAPSENSE displays sense information for an attached real or defined virtual tape drive. Using the current CSL-WAVV comments on the Linux-390 list of give to get I have included the following as general information. Please feel free to ignore it as we had planned to make these utilities available anyway. An earlier version of our LXFMT utility was made available on the Sinenomine.net website last year. While at our website feel free to browse information on our VM virtualization products VTAPE (Virtual TAPE) and VPARS (Virtual Private Active Record Shadowing for TPF and Linux). I will be presenting technical information on both VPARS and VTAPE at SHARE in Orlando, Session 9155 Tuesday 2/26 at 8am and a Vendor Session Wednesday 2/27 at 4:30pm in Laredo 1. We will also be available at booth 322 at the SHARE Technology Expo with demos, I hope (if all the internet stuff works to get to our mainframe ;-). Our FLEX-ES laptop expired 2/2007 making us dependant on the internet for demos ;-(. We will also be at WAVV in Chattanooga in April. Having been a member of SHARE since the early 1970's but not attending in several years I look forward to renewing many old friendships, making new ones and thanking the VM Group members for my Knighthood at the last SHARE.

What I have been doing up to this point for a new z/Linux guest build is, not necessarily in this order and does not necessarily include all steps but, Crave out the DASD for the z/Linux guest Init the DASD using CPFMTXA putting a label on the disk Setting up the Directory entry for the new guest, which includes specifying the MDISK for all of the DASD for the guest. We back up our z/Linux guests on the z/OS side with DFDSS. My question is since when we Kick Start the new z/Linux guest and it initializes the DASD during this process is there any compelling reason for me to initialize the DASD up front before the guest is Kick Started for the first time basically doing a double INIT? If not I assume then I would replace the MDISK statements in the Directory entry with DEDICATE statements for each one of the DISKS. We do not share DASD between guests here so what is defined to the guest belongs to that guest only. Is there anything to be aware of by changing to DEDICATE statements from MDISK statements? My only concern is with the DFDSS backups that I do on the z/OS for the guests. I am not sure if it matters or not to DFDSS whether the pack was initialized via CPFMTXA or z/Linux during the kick start process?
