Re: Command to list details about the exisitng partitions / guest on zVM
You¹ll find that most z/VM¹ers will use userid, guest, image, and virtual machine interchangeably. Sometimes in the same paragraph, and possibly in the same sentence. Sorry; they¹re all just part of the history of the beast. But yes, if you log off the user, you¹ve ³powered off² the virtual machine. The ³magic number² on the IPL command that you refer to as some number is really the virtual CCUU of the disk device you¹re IPLing from. CCUU being the channel and unit number. This number should lead you to a device in the virtual machine¹s definition, which may be an MDISK or a DEDICATE, and will then lead you to a real device on your system. The virtual machines that are defined but not active will only be accurately listed in the CP Directory. Look through it, and try to eliminate any of the users that are created by the z/VM installation. What is left will be your CMS users and your Linux guests. You¹ll have to look at the minidisks of each individually to decide what they really are. -- .~.Robert P.

I was also able to bring up the virtual machine / guest os using the IPL commands. I did this because I knew the IPLSYS for the Virtual machine from one of my earlier screenshot and was able to IPL with IPL some number CLEAR command. However I still need to find out details about the virtual machines that are defined but not active. and IPL them.
Re: Command to list details about the exisitng partitions / guest on zVM
Thanks for the console log; The most interesting command you¹ve shown here is: QUERY NAMES LINUXFTP - DSC , PERFSVM - DSC , TCPIP - DSC , DTCVSW2 - DSC DTCVSW1 - DSC , OPERSYMP - DSC , DISKACNT - DSC , EREP - DSC TCPMAINT - DSC , BEADEV01 -L0003 VSM - TCPIP This tells you what is logged in on your system. Of these users, most can be accounted for as standard z/VM service machines. The two that are not, are BEADEV01 and LINUXFTP (although this could be TCPIP¹s ftpserve under a different name; You¹d have to log into it to see if it really is running Linux.) From the others, I¹d say you have a vSwitch active (because DTCVSW1 and 2 are the controllers for a vSwitch) and you have the IBM Performance Toolkit (the service machine PERFSVM). I¹m not sure why TCPMAINT would be logged in disconnected. This isn¹t needed for anything. OPERSYMP, DISKACNT and EREP are collectors for various information produced by z/VM. I¹m surprised to not see OPERATOR logged in on a terminal. The user you need to log into (due to the fact that it has the ³keys to the cabinet²) is MAINT. MAINT is the equivalent to Linux¹s root account. Since I don¹t see DIRMAINT running on your system, I¹d assume that the current CP Directory is on one of MAINT¹s minidisks, probably named USER DIRECT. You need to be able to log into MAINT to perform even minor maintenance tasks on the system. Hopefully someone has left you the password. The reason that you immediately see a Linux logon when you log into the system is that you¹re logging into a user that is running a Linux guest. You need your own, personal userid, so that you can easily log in and issue commands. Once you find the CP Directory, it should be a simple task to add one for yourself. Key to stepping into all this mud would be to look at the CP Administration and Customization manual. It describes the contents of the CP Directory file and how to put it into production, and also describes the SYSTEM CONFIG file, found on MAINT¹s CF1, 2, and 3 minidisks. Do lots of querys and look at the files that MAINT and TCPMAINT control. Don¹t change anything until you understand what those changes will affect. Good luck, and good hunting. -- .~.Robert P.

Re: VMNFS question
Mary, thanks for the reply.

Turn on the 502 trace using the SMSG command (SMSG VMNFS M MASK 502) or by updating the :parms tag in the DTCPARMS file and try again. If the request is getting there, that should show you why it is failing.

I have our OSA setup such that there are two IP addresses into the mainframe. Same subnet. 1st IP addr. Is nnn.nnn.nnn.173 and the second is nnn.nnn.nnn.175. Also involved in this are two Linux instances, one on the mainframe, the other on a laptop. The linux on the mf has an VM NFS mounted using the .173 When I try to issue the same mount command on the linux laptop, it won't make a connection. Looking at the VMNFS console output doesn't give a clue as to why. When I issue the same mount command again, but use .175 I'm able to mount the drive. Does VMNFS allow only one connection to one mount point using the same IP addr? Thanks, Steve G. = ===
