list. Normal virtual processors in the dispatch list will be Q x (x=1,2,3). Eligible list would be marked as E x . The third column in the example also gives state of virtual processor. This can be helpful to get a idea of how the virtual processors might be constrained. Virtual processors that are actually running in the snapshot period are marked with and RNN where NN is the processor number they are on. An R without a number means the virtual processor is ready to run but there is not an available processor. (Note: the virtual machine that issues the INDICATE command will always be one of the running machines). Other states are documented in the help for IND Q EXP. One doesn't have to be concerned about the other columns unless detailed analysis is required or if IBM support requests it. Also, always remember that is just a snapshot in time so often repeating this command over time can give a more accurate picture of your z/VM system, a single snapshot cannot be regarded as indicative. 14.1.2 Using other basic commands Some other useful basic commands are briefly mentioned. All examples are shown from the MAINT user ID. The results will be different for users with fewer privileges. Getting help To get help on the system use the HELP command. Sometimes it’s hard to find help for exactly the command you’re looking for. Some useful help commands are as follow ==> help // for basic help ==> help menus // for menu of all z/VM help menus ==> help cp menu // for a menu of all CP commands ==> help cpquery // for a menu of all CP QUERY command ==> help cpset // for a menu of all CP SET commands Determining who is logged on To see who is logged on to the system use the QUERY NAMES command. For example: ==> q n FTPSERVE - DSC , LINUX04 - DSC , LINUX03 - DSC , LINUX02 - DSC LINUX01 - DSC , S11S1CLN - DSC , DTCVSW2 - DSC , DTCVSW1 - DSC VMSERVR - DSC , VMSERVU - DSC , VMSERVS - DSC , TCPIP - DSC OPERSYMP - DSC , DISKACNT - DSC , EREP - DSC , OPERATOR - DSC MAINT -L0003 VSM - TCPIP Determining storage or memory To see how much central and expanded storage (memory) are installed and allocated to a system use the QUERY STORAGE and QUERY XSTOR commands. For example: ==> q stor STORAGE = 16G CONFIGURED = 16G INC = 256M STANDBY = 0 RESERVED = 0 ==> q xstor XSTORE= 2048M online= 2048M XSTORE= 2048M userid= SYSTEM usage= 0% retained= 0M pending= 0M XSTORE MDC min=0M, max=0M, usage=0% XSTORE= 2048M userid= (none) max. attach= 2048M Determining processors or CPUs To see how many processors (CPs, IFLs, CPUs) you have allocated at system level, use the QUERY PROCESSORS command. For example: ==> q proc PROCESSOR 00 MASTER CP PROCESSOR 01 ALTERNATE CP 226 The Virtualization Cookbook for RHEL 6
PROCESSOR 02 ALTERNATE CP PROCESSOR 03 ALTERNATE CP PROCESSOR 04 ALTERNATE CP PROCESSOR 05 ALTERNATE CP PROCESSOR 06 ALTERNATE CP PROCESSOR 07 ALTERNATE CP PROCESSOR 08 ALTERNATE CP PROCESSOR 09 ALTERNATE CP Determining software level To determine what level of CP your system is at, use the QUERY CPLEVEL command. For example: ==> q cplevel z/VM Version 6 Release 1.0, service level 0901 (64-bit) Generated at 09/11/09 16:51:48 EDT IPL at 08/31/10 08:44:19 EDT Determining system cylinder allocation The QUERY ALLOC MAP command shows you the system allocation of spool, paging and directory space. For example: ==> q alloc map EXTENT EXTENT % ALLOCATION VOLID RDEV START END TOTAL IN USE HIGH USED TYPE ------ ---- ---------- ---------- ------ ------ ------ ---- ------------- 610RES 6280 1 20 20 1 1 5% DRCT ACTIVE UV6281 6281 1 3338 600840 75482 75533 12% SPOOL UV6282 6282 1 3338 600840 0 0 0% PAGE UP6285 6285 0 3338 601020 0 0 0% PAGE UP6286 6286 0 3338 601020 16 59 1% PAGE UP6287 6287 0 3338 601020 0 0 0% PAGE Determining DASD, OSA and virtual resources The QUERY DASD and QUERY DASD FREE commands will show you what DASD is assigned to the system and what DASD is free to be assigned. Similarly the QUERY OSA and QUERY OSA FREE commands will report on the OSA resources. Finally, the QUERY VIRTUAL ALL command can be useful. The following list gives the short form of these commands without any of the associated output shown: ==> q da ==> q da free ==> q osa ==> q osa free ==> q v all 14.2 The z/VM Performance Toolkit To use the z/VM Performance Toolkit, the product must be ordered. You should only configure the product if you have ordered it.
