You may want to ask this on the VM List, which is quite active.

TLDR: Change to USER DIRECT has destroyed PMAINT access to the USER DIRECT file and PARM MDISK. Is there a recovery path to get back? ------------------------- Here is some background. I dived into z/VM a lot of years ago and with the help of Redbooks and SHARE got some working Linux servers under z/VM and SLES Linux with an IFL on a z12BC mainframe. Time fades and knowledge fades. Due to the neglect to this setup, z/Vm 6.4 will no longer IPL on our new z15 box. I jumped in and installed a new z/VM 7.3 SSI system from scratch. I then looked for a way to get the machines defined under z/VM 6.4 to be defined under z/VM 7.3. I wanted to read the old 6.4 USER DIRECT to get the USER definitions out and insert them into the 7.3 USER DIRECT.. I followed the practice of copying a USER DIRECT to a backup USER DIRExxxx file. The edit of USER DIRECT was performed to define MDISKs to PMAINT that 'shadow' the new 7.3 MDISKs with where I hoped the 6.4 MDISKs were still holding the old machine entries. **** here is where it goes painfully wrong **** Something in the edit caused the newly loaded (DIRECTXA) to lose touch with the 2CC PMAINT disk. Now NOONE ANYWHERE can LINK or ACCESS this space. Not even to list files or activate the backup file. The key to the piggy bank is now locked IN the piggy bank. ---------- Some answers to the first wave of questions: Is the raw 3390 disk backed up somewhere? ---- As a z/OS shop with DFSMSdss - handling CPFORMAT volumes was not easily added to our backup systems. ---- General questions: How damaged am I? I am trying to NOT lose the time spent so far on install. If I do go back. Should I look into the Migration method of installation? Does migration require that the prior system be IPL able? Can Migration handle the change from old style non-SSI to SSI? I think I am going to have to kiss a couple of weeks work goodbye. Good think I left the USB install media stuck in my HMC. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
