Multipath alias problem
Our z/VM is Version 5.4. z/Linux is SUSE 11 SP1.
I'm going to add one SCSI disk(from 2 FCP type sub-channels,to 2 SAN
switchs, to 2 HBA port of DS8000) and use multipath.
The following is what I did:
(1)use YAST2 to add 2 zfcp disks(actually they are one SCSI disk).
successful
(2)use mkinitrd command. The response messages are different with those of
SUSE 10, I'm not sure if they are correct.
LXCPOA:/ # mkinitrd
Kernel image: /boot/image-2.6.32.12-0.7-default
Initrd image: /boot/initrd-2.6.32.12-0.7-default
Root device:/dev/disk/by-path/ccw-0.0.0200-part1 (/dev/dasda1) (mounted
on / as ext3)
Kernel Modules: jbd mbcache ext3 dasd_mod dasd_eckd_mod
Features: block dasd resume.userspace resume.kernel
25502 blocks
(3)use zipl command. The response messages are also different with those of
SUSE 10, I'm not sure if they are correct.
LXCPOA:/ # zipl
Using config file '/etc/zipl.conf'
Building bootmap in '/boot/zipl'
Building menu 'menu'
Adding #1: IPL section 'SLES11_SP1' (default)
Adding #2: IPL section 'FailsafeV1'
Adding #3: IPL section 'ipl'
Preparing boot device: dasda (0200).
Done.
(4)use lsscsi command to show available zfcp disks. And check their
information. successful(I think)
LXCPOA:/ # lsscsi

LXCPOA:/ # cat /sys/class/scsi_device/1:0:0:1073758208/device/hba_id
0.0.3f00
(5)At this point, there is no multipath.conf file in system, so I created
new one.
LXCPOA:/etc # cat multipath.conf
multipaths{
multipath{
wwid 36005076308ffc621
alias mpvol1
}
}
(6)I want to enable new alias, so I enable multipath again. But nothing is
shown, is there a error?
LXCPOA:/etc # multipath
LXCPOA:/etc #
(7)use YAST2 to have a file system created on it and mounted. successfuly
(8)check new directory. I don't know why my alias to this disk is not
used!!!
LXCPOA:/ # df -h

(9)I upload a 1G file by FTP to new directory to check if IO load is
balanced among 2 paths.
Is balance sucessful? Why the tps value for dm-0 and dm-1 is so
different?

Re: Found duplicate PV in Guest Linux SUSE 10
HI: When installing SUSE 11 I created a VG boot and associated with LV boot, which only occupies 80 megabytes. Likewise I created a VGroot--- LVroot for the root file system with a size of 2 gb.

Now hat hapening whit my DASD In the new guests clone I format all DASDs (11 dasds) with the command CP CPFMTXA, once this is done for each DASD, I restored disk image files whit PIPEDDR restore command. Only Restore 11 dasds. The problem arises when incorporate more DASDs for the New Applicatios file systems. In this case the disk that has the problem was incorporated for the NetBackup Product. when I add these new dasds is when have the problem of the duplicate UUID. (Dasd 607) Dasd 607 have duplicate UUID. 607 is new for this server. I hope explained correctly. I'll try the solutions you shared with me and I tell them the result Saludos ATTE Victor Hugon Ochhoa Avila 2011/9/7 Richard Troth vmcow...@gmail.com You said you have no overlaps, but what Mark Post said still applies. Was a minidisk copied (enlarged? moved?) and the original space not wiped clean? If so, then any PV signature would still be present and would appear on the (new to Linux) device. I am suspicious of your 400 minidisk (/dev/dasdf). It is only 80M and that is rather small for typical use as a PV. (But you have a vgboot volume group.) Look again at what Mark said, that has the same UUID as your 607 minidisk (/dev/dasdp). There is no way to fix that with filtering. Then bring in what Marcy said, so perhaps it is possible to accidentally get the same UUID on two PVs. Other than that, one of those two minidisks would have to be a partial copy of the other. I hope this helps. Please let the group know when you get things worked out ... and how.

If these ids are going to be temporary, add -e to the useradd command and specify an expiration date so they automatically go locked when the class is over. You're dealing with two things here: real and effective uids. Each user normally must have a single unique numeric uid that should be unique across all systems. This is stored in /etc/passwd, and is known as their real uid (the one that determines permanent file ownership, etc). The _effective_ uid is the one that is used when executing programs, etc at the time of execution. Normally the real and effective uid are the same, producing no special powers. 'su' (and by extension, sudo and a an appropriate filter) temporarily change the effective uid for that user in that process context to 0, temporarily giving them powers beyond the mortal *for the duration of that process context*. In the case of sudo, a new process context is created, the command is parsed, and then checked against the patterns in /etc/sudoers. If the command matches a pattern in /etc/sudoers, sudo temporarily changes the effective uid of the process to 0, does the command, and immediately changes the effective uid back to the real uid when the command is completed and before the user is given control again. If the command is an interactive command like a shell (remember, Unix shells are just programs), the process retains the superuser privilege until the original shell started by sudo exits, and other commands issued from that shell inherit the Powers of Darkness from the 'sudo bash' command. These days, sudo is the way to go if you have multiple administrators who need superuser access. Much safer, and you don't ever have to give anyone the REAL root password (as you do with su) -- they authenticate with their OWN password before anything dangerous happens, effectively making them directly responsible for what they do. Third, how do I list the userid after it's created? cat /etc/passwd | grep userid -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/ -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For more information on Linux on System z, visit http://wiki.linuxvm.org/

Re: Ubuntu on z?
Is Debian on server better then Ubuntu? I'm happy to learn :-) I just prefer to run the same distro across my devices... and Ubuntu was the first desktop distro that worked out of the box on my laptop and desktop. That's what made me an Ubuntu fan, and as such I use their other versions as well.

I played with Ubuntu for a few days on a new Dell desktop I bought several
years ago, but that wasn't long enough to try a version upgrade. I _have_ done
that on SLES several times, and it usually just worked for me. There were
certainly some problems in some cases, such as when the transition to using
/dev/disk/by-{id,path} happened, but prior to and after that it's been pretty
smooth sailing.

(2)use mkinitrd command. The response messages are different with those of
SUSE 10, I'm not sure if they are correct.

Unless you're changing something about your root file system, regenerating the

Done.
If you don't update your initrd, you don't need to re-run zipl (in this
particular context). But again, the output looks fine.

information. successful(I think)

The first set of output from iostat is from the time of system startup until
now. You might be better off running iostat continuously (iostat 2 or iostat
5) and watching how things are working. In your multipath.conf file you didn't
specify a path_grouping_policy. I don't know what the default is. It may or
may not be one that provides load balancing. It may be providing failover.

Re: Ubuntu on z?
Yeah, you CAN do it (and there are people who try it often), but there are always a few glitches with the upgrade-in-place tools for RHEL and SLES. I've got Debian machines that have gone through repeated major release updates with 100% reliability. You can't beat: 1) Add new repository into /etc/apt/apt.sources 2) apt-get update 3) apt-get dist-upgrade And it Just Works. No muss, no fuss, no hassle. Fire and walk away. I also think apt does a better job of not clobbering customizations if there's already a file in place. Not all RPMs play nice with that. Ubuntu Server I can easily see being interesting; it's a little less conservative than the enterprise releases in terms of being more up to date, but not as freewheeling as Fedora on Intel's let's release a new kernel every 11.5322555 minutes because we can philosophy. Nice golden mean. Ubuntu also has the name recognition that plain Jane Debian does not. Fortunately, we don't care about desktops on Z, so we don't have to have the Unity vs GNOME argument here.
