Info

You should see that the VSWITCH VSW1 exists, that the OSA devices you specified are being used and that there are two built-in VSWITCH controllers, DTCVSW1 and DTCVSW2. 4. Use the QUERY RETRIEVE and QUERY VDISK commands to see the changes made to the Features statement in the SYSTEM CONFIG file: ==> q retrieve 99 buffers available. Maximum of 255 buffers may be selected. ==> q vdisk userlim VDISK USER LIMIT IS INFINITE ==> q vdisk syslim VDISK SYSTEM LIMIT IS INFINITE, 0 BLK IN USE This shows that the changes to the SYSTEM CONFIG file have taken effect. 4.6 Adding paging volumes The z/VM operating system resides on the first three CP volumes (or one volume if installing onto 3390-9s). z/VM 6.1 is installed with one full paging volume and one full spool volume. A single spool volume is probably adequate for Linux needs, however, a single paging volume is probably not. It is recommended that you add at least three paging volumes so you will have a total of four (or one more 3390-9). Having adequate paging space will give you plenty of headroom to add more Linux virtual machines. A rule of thumb for the amount of paging space is to have twice as much as the total of all memory for all running Linux user IDs combined. 4.6.1 Formatting the paging volumes Before adding paging volumes to the system, the DASD volumes to be used for minidisk space (PERM) and paging space (PAGE) must be formatted. Normally this is done one volume at a time using the CPFMTXA command. If you have just a few volumes, that is fine, but when you have many volumes to format, the process of running CPFMTXA can become time consuming and tedious which can lead to errors. Therefore, a REXX EXEC named CPFORMAT has been provided to allow you to format many volumes with a single command. The source code for this EXEC is in the section B.2.1, “The CPFORMAT EXEC” on page 244. It is a wrapper around CPFMTXA. To use this EXEC, each DASD to be formatted must first be attached with the virtual device address the same real device address (using ATTACH realDev *). Note: This EXEC will label the volumes according to the convention described in 2.2.1, “Volume labeling convention” on page 9. If you want different volume labels, you can use the CPFMTXA command and manually specify each volume label, or you can modify the REXX EXEC. Getting the CPFORMAT EXEC to z/VM Perform the following steps: ► Logoff of MAINT so you will be able to get the MAINT 191 disk in read-write mode using FTP. Important: At this point, you will need access to the NFS server described in chapter 6, in order to get the files CPFORMAT EXEC. If you did not complete that chapter, it is required in order to proceed. 50 The Virtualization Cookbook for RHEL 6
► Start an SSH (putty) session to the NFS server and change to the vm/ directory which was created when you untarred the files associated with this book. Verify that the file CPFORMAT.EXEC exists: # cd /nfs/virt-cookbook-RH6/vm # ls cpformat* cpformat.exec ► Start an FTP session to z/VM. If you get a reply from the FTP server it shows that you correctly configured it on the z/VM TCPMAINT user ID. Issue the PUT subcommand to copy the file. # ftp 9.60.18.249 Name (9.12.5.22:root): maint 331-Password: maint 230-MAINT logged in; working directory = MAINT 191 ... ftp> put cpformat.exec ... ftp> quit You should now have the CPFORMAT EXEC on MAINT 191 disk. Using the CPFORMAT EXEC To use the CPFORMAT EXEC, perform the following steps: ► Log back into MAINT. You should now have access to the CPFORMAT EXEC. You can get brief help on CPFORMAT by using a parameter of “?”: ==> cpformat ? Synopsis: Format one or a range of DASD as page, perm, spool or temp disk space The label written to each DASD is U where: is type - P (page), M (perm), S (spool) or T (Temp disk) is the 4 digit address Syntax is: .-PAGE-. >>--CPFORMAT--.-rdev--------------.--AS---+-PERM-+--------->< | q 6285 6286 6287 DASD 6285 UM6285 , DASD 6286 UM6286 , DASD 6287 UM6287 ► Attach the devices to MAINT (the last parameter of * means the current user ID) using the ATTACH command: ==> att 6285-6287 * Chapter 4.
