Running REXX compiled in z/OS in CMS
Hi, Here's a question that's half way between z/OS and CMS: I would like to compile some REXX in z/OS in such a way that it can be run in CMS by people who don't have the REXX compiler. From reading the manual, I thought that just specifying options of ALTLIB and SLINE would be sufficient, but this doesn't seem to be the case. I can make it work by XEDITing the compiled exec and changing the processor name in the header from EAGRTPRC to DMSRTPRC, but that surely isn't what IBM intend us to do. Does anyone know the legitimate way of doing this? Thanks, Mark Gillis Principal Software Engineer Tel: +61 2 8898 2678 Fax: +61 2 8898 2600 mark.gil...@ca.com mailto:mark.gil...@ca.com http://www.ca.com/

Re: Cannot see SVC disk zLinux
Terry, /var/log/messages looks ok. 49409 (0xc101) is the well known LUN to issue report_luns against. So lsluns is doing the extra step to create an sg device for these target ports without any storage configured. As I alluded to in my previous note, I'd try to do this manually. Either by editing a copy of lsluns or by doing it completely by hand. Maybe like this: lsscsi -g take note of what is there chccwdev --online 0.0.5401 echo 0x500507680110a31b /sys/bus/ccw/drivers/zfcp/0.0.5401/port_add you might not need this step echo 0x /sys/bus/ccw/drivers/zfcp/0.0.5401/0x500507680110a31b/unit_add echo 0xc101 /sys/bus/ccw/drivers/zfcp/0.0.5401/0x500507680110a31b/unit_add lsscsi -g figure out what is new, one of the unit_add's should make a new sg device sg_luns /dev/sgXXX where XXX is whatever you determined was new in the last step Hopefully, the last step gives you more meaningful error messages.

Re: Running REXX compiled in z/OS in CMS
Mark, Many VM releases ago, VM Development wanted to have all customers benefit from performance improvements for some of the items that were written in REXX. You know about these parts like VMLINK, NOTE, SENDFILE, FILELIST and many others. However, we could not assume that all customers would install the REXX Alternate Library and customers would want to use these parts even before they got around to installing the REXX Alternate Library. So VM Development created a DMSRTPRC which is a library which is sufficient for the compiled REXX parts that are shipped with the VM product. It is not to be used by our customers for their own use because it is not supported for general use. There is no guarantee that your compiled part will run if you edit it to use DMSRTPRC. VM Development will not service DMSRTPRC if it does not work with your compiled part. We will service it if it fails with one of the parts that are compiled and shipped as part of VM. pdb (Doug Breneman) z/VM System Test IBM Endicott, NY From: Gillis, Mark mark.gil...@ca.com To: IBMVM@LISTSERV.UARK.EDU Date: 04/13/2011 04:26 PM Subject:Re: Running REXX compiled in z/OS in CMS Sent by:The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU Thanks, Tracy.

Re: Dirmaint : cards ordre
Alain, The CP Planning and Administration manual, have a paragraph for each command, saying where to code each. For INCLUDE, by example, says MUST follow the USER card. No other cards are allowed between them. Personally, I prefer to use DIRMAINT to do the changes. Example: A batch file with all the ACCOUNT cards is more easy to create than edit the source USER DIRECT. Like it: FOR USER1 ACCOUNT ACCT1 FOR USER2 ACCOUNT ACCT2 FOR USER3 ACCOUNT GRP001 ... FOR USER999 ACCOUNT GRP600 Only one command can process all the entries in this file: DIRM BATCH batch file All are correctly positioned.

Great - now it all makes sense. We'll just pre-req the alternate library for our product. Thanks. From: The IBM z/VM Operating System [mailto:IBMVM@LISTSERV.UARK.EDU] On Behalf Of Doug Breneman Sent: Thursday, 14 April 2011 6:37 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Running REXX compiled in z/OS in CMS Mark, Many VM releases ago, VM Development wanted to have all customers benefit from performance improvements for some of the items that were written in REXX. You know about these parts like VMLINK, NOTE, SENDFILE, FILELIST and many others. However, we could not assume that all customers would install the REXX Alternate Library and customers would want to use these parts even before they got around to installing the REXX Alternate Library. So VM Development created a DMSRTPRC which is a library which is sufficient for the compiled REXX parts that are shipped with the VM product. It is not to be used by our customers for their own use because it is not supported for general use. There is no guarantee that your compiled part will run if you edit it to use DMSRTPRC. VM Development will not service DMSRTPRC if it does not work with your compiled part. We will service it if it fails with one of the parts that are compiled and shipped as part of VM. pdb (Doug Breneman) z/VM System Test IBM Endicott, NY Inactive hide details for Gillis, Mark ---04/13/2011 04:26:40 PM---Thanks, Tracy.

Re: Dirmaint : cards ordre
Alain, Normally, this kind off migration is done on few hours. My technique (resumed): 1- Install a new VM and enable DIRMAINT, with the supplied directory. 2- Split the old direct to a TEMP disk, using one homemade EXEC (DIRSPLIT). The exec reads the old USER DIRECT, and create a new -userid- DIRECT, for each machine. Based on the USER card. Each USER finish the previous. Also test if each -userid- exist (CP QUERY USER -userid-). If exist then rename the file to -userid- EXIST. 3- DIRM ADD for all the -userid- DIRECT created. 4- Manually inspect the EXIST files and create a batch file for the divergences: ACCOUNT, ACIGROUP, new MDISK, etc. A DIRM GET followed by COMPARE can help. 5- Make the adjusts: DIRM BATCH batch file 6- If needed, move the old machines to new dasds: DIRM CMD (depending on the number of machines to move, eventually I create additional DATAMOVs...) 7- Fine adjust (less than 2%) for not covered situations.

Terry, Aren't you referring to host connections, which is sometimes called lun masking? Here we use type = generic when adding hosts on the SVC console. Since the sg devices get created, I don't think there is a zoning problem. Linux can obviously get to the target wwpn because it figured out that there is a 2145 SVC there. I think there is a problem with the hosts that were specified on the SVC console. I tried to do lsluns with a channel that is unknown to our SVC and got the same messages as you: root@Laplace-4E15:lsluns -c 0.1.7900 -p 0x5005076801104bac Scanning for LUNs on adapter 0.1.7900 at port 0x5005076801104bac: Unable to send the REPORT_LUNS command to LUN. I then configured the well known lun by hand, and also got the same messages as you: root@Laplace-4E15:sg_luns /dev/sg4 Report Luns command has bad field in cdb So I ran it again with -v root@Laplace-4E15:sg_luns -v /dev/sg4 report luns cdb: a0 00 00 00 00 00 00 00 20 00 00 00 report luns: Fixed format, current; Sense key: Illegal Request Additional sense: Logical unit not supported Info fld=0x0 [0] Report Luns command has bad field in cdb Those are the real error messages that I was hoping for!

Not sure how the LUNS know they belong to my ZFCP id of 0.0.5400 Messages below from lsluns pr 13 16:23:31 zlinux1 kernel: scsi scan: INQUIRY successful with code 0x0 Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: Direct-Access IBM 2145 PQ: 1 ANSI: 4 Apr 13 16:23:31 zlinux1 kernel: sg_alloc: dev=1 Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: Attached scsi generic sg1 type 0 Apr 13 16:23:31 zlinux1 kernel: sg_open: dev=1, flags=0x8802 Apr 13 16:23:31 zlinux1 kernel: sg_add_sfp: sfp=0x1ef62000 Apr 13 16:23:31 zlinux1 kernel: sg_build_reserve: req_size=32768 Apr 13 16:23:31 zlinux1 kernel: sg_build_indirect: buff_size=32768, blk_size=32768 Apr 13 16:23:31 zlinux1 kernel: sg_build_indirect: k=0, num=32768, ret_sz=32768 Apr 13 16:23:31 zlinux1 kernel: sg_build_indirect: k_use_sg=1, rem_sz=0 Apr 13 16:23:31 zlinux1 kernel: sg_add_sfp: bufflen=32768, k_use_sg=1 Apr 13 16:23:31 zlinux1 kernel: sg_ioctl: sg1, cmd=0x2285 Apr 13 16:23:31 zlinux1 kernel: scsi_block_when_processing_errors: rtn: 1 Apr 13 16:23:31 zlinux1 kernel: sg_common_write: scsi opcode=0xa0, cmd_size=12 Apr 13 16:23:31 zlinux1 kernel: sg_start_req: dxfer_len=8192 Apr 13 16:23:31 zlinux1 kernel: sg_link_reserve: size=8192 Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: [sg1] Send: 0x1e35dd00 Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: [sg1] CDB: Report luns: a0 00 00 00 00 00 00 00 20 00 00 00 Apr 13 16:23:31 zlinux1 kernel: buffer = 0x1e4ead00, bufflen = 8192, queuecommand 0x03c0009cf8dc Apr 13 16:23:31 zlinux1 kernel: leaving scsi_dispatch_cmnd() Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: [sg1] Done: 0x1e35dd00 SUCCESS Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: [sg1] Result: hostbyte=DID_OK driverbyte=DRIVER_OK Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: [sg1] CDB: Report luns: a0 00 00 00 00 00 00 00 20 00 00 00 Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: [sg1] Sense Key : Illegal Request [current] Apr 13 16:23:31 zlinux1 kernel: Info fld=0x0 Apr 13 16:23:31 zlinux1 kernel: scsi 0:0:0:49409: [sg1] Add.

Terry, Aren't you referring to host connections, which is sometimes called lun masking? Here we use type = generic when adding hosts on the SVC console. Since the sg devices get created, I don't think there is a zoning problem. Linux can obviously get to the target wwpn because it figured out that there is a 2145 SVC there. I think there is a problem with the hosts that were specified on the SVC console. I tried to do lsluns with a channel that is unknown to our SVC and got the same messages as you: root@Laplace-4E15:lsluns -c 0.1.7900 -p 0x5005076801104bac Scanning for LUNs on adapter 0.1.7900 at port 0x5005076801104bac: Unable to send the REPORT_LUNS command to LUN.
