Solaris Volume Manager help needed...

I am new to Solaris Volume Manager and need some assistance. I suspect that the mirroring was no setup correctly on a server I am concerned with. Here is some output:

Any help and/or links to information for proper setup of mirroring when using Solaris Volume Manager would be appreciated. I should mention that the system also uses Veritas Volume Manager 4.1, but only Solaris Volume Manager is in control of the mirroring.

  • How do you change volume permissions with Solaris Volume Manager?

    (Previously posted in "Talk to the Sysop" - no replies)
    I'm trying to set up Solaris 9 to run Oracle on raw partitions. I have my design nailed down and I have built all the raw partitions I need as soft partitions on top of RAID 1 volumes. All this is built using Solaris Volume Manager (SVM).
    However, all the partitions are still owned by root. Before I can create my Oracle database, I need to change the owner of the Oracle partitions to oracle:oinstall. The only reference I found telling me how to do this was in a Sun Blueprint and it essentially said "You can't change volume permissions directly or permanently using SVM and chown will only remain effective until the next reboot. To make the changes permanent, you must modify /etc/minor_perm". Unfortunately, I can't find an example of how to do this anywhere and the online man pages are not particularly helpful (at least not to me).
    I'd appreciate a quick pointer, either to a good online resource or, even better, a simple example. For background, the volumes Oracle needs to own are:
    /dev/md/rdsk/d101-109
    /dev/md/rdsk/d201-203
    /dev/md/rdsk/d301-303
    /dev/md/rdsk/d401-403
    /dev/md/rdsk/d501-505
    I provide this information because I'd like to assign some, but not all, of the devices under /dev/md/rdsk to the oracle user and I was hoping some smart person out there could illustrate an approach using simle regular expressions, at which I'm horribly poor.
    Thanks in advance,
    Adrian

    Ron, I feel your pain.  I just came from an HTC also and a lot of stuff with this iPhone is bugging the crap out of me.  Who makes a phone where you can't adjust the ringer and alert volumes independently?  Instead, I have to adjust the alert volume when it is active.  C'mon guys.  Get with the program.  You won a bunch of Android users over with the 4S, but you're going to chase us all back when we're done with our contract.  Frustrating.  

  • Solaris Volume Manager Enhanced Storage BUG?

    All of our 64 bi sparc machines from solaris 8 and up used the Solstise Disk Suite...now solaris volume manager. The default solaris 10 install installs the command line metadb and other tools. I did formerly enjoy the metatool command for configuring the disk with GUI. I start the Management Console then I select Enhanced Storage and the Management Console just hangs. Is this because something is missing from my path. Or do I need to install more packages? If so what are these packages and where can I get them. I am also looking for the old versions of metatool for solaris 8 and 9 and ideas where I could find these?

  • Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with re

    Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with reddish cast and loss of detail
    System: Windows 7
    Adobe CS5
    Printer: Epson Stylus Photo 1400
    Paper: Inkjet matte presentation paper with slight luster
    Installed latest patch for Adobe CS5
    Epson driver up to date
    After reading solutions online and trying them for my settings for 2 days I am still unable to print what I am seeing on my screen in Adobe CS5. I calibrated my monitor, but am not sure once calibration is saved if I somehow use this setting in Photoshop’s color management.
    The files I am printing are photographs of dogs with lots of detail  I digitally painted with my Wacom tablet in Photoshop CS5 and then printed with Epson Stylus 1400 on inkjet paper 20lb with slight luster.
    My Printed images lose a lot of the detail & come out way to dark with a reddish cast and loss of detail when I used these settings in the printing window:
    Color Handling: Photoshop manages color, Color management -ICM, OFF no color adjustment.
    When I change to these settings in printer window: Color Handling:  Printer manages color.  Color management- Color Controls, 1.8 Gamma and choose Epson Standard it prints lighter, but with reddish cast and very little detail and this is the best setting I have used so far.
    Based on what I have read on line, I think the issue is mainly to do with what controls are set in the Photoshop Color Settings window and the Epson Printer preferences. I have screen images attached of these windows and would appreciate knowing what you recommend I enter for each choice.
    Also I am confused as to what ICM color management system to use with this printer and CS5:
    What is the best ICM to use with PS CS5 & the Epson 1400 printer? Should I use the same ICM for both?
    Do I embed the ICM I choose into the new files I create? 
    Do I view all files in the CS5 workspace in this default ICM?
    Do I set my monitor setting to the same ICM?
    If new file opens in CS5 workspace and it has a different embedded profile than my workspace, do I convert it?
    Do I set my printer, Monitor and PS CS5 color settings to the same ICM?
    Is using the same ICM for all devices what is called a consistent workflow?
    I appreciate any and all advice that can be sent my way on this complicated issue. Thank you in advance for your time and kind help.

    It may be possible to figure out by watching a Dr.Brown video on the subject of color printing. Adobe tv
    I hope this may help...............

  • How Solaris Volume Manager sync submirrors

    HI Gurus,
    I have a question on how Solaris volume manager (SVM) does re-synchronization (in raid 1). In another word, in case of one submirror was modified during boot process, how SVM detects it and how SVM validate which sumirror is gold.
    One scenario I ran into: We had a software installed, this software updated /etc/name_to_sysnum which conflicts with new Solaris 10 release. So the system could not boot any more (not even to single user mode) after software installed. This box had root disk mirrored. To fix this, we boot from CDROM and mounted 1st mirror drive root partition (c0t0d0s0) and remove the bad entry in /etc/system (we did not break the mirror to make the changes). Then the box was able to boot up. After server was up, it was found /etc/system was rolled back with bad entries. Apparently it was synced back from 2nd mirror. So now the question is how SVM decides which submirror is invalid and should be re-sync from good submirror?
    2nd scenario I saw: someone accidently added one root file system submirror into zone as a file system. But during zone installation, system got panic and rebooted. During reboot, system kept crashing. We managed to boot from network, break the mirror (update /etc/vfstab and /etc/system) and finally was able to boot the system. So in case one submirror was accidently accessed, how does SVM protect data and will the corrupted data written to disk slice synced to good submirror?
    Please share your thoughts and point me with some good references. I could not find related info in SVM doc.
    Thanks,
    Wei

    SVM doesnt "sync" disks ie copy data from one disk to another except in the case when your first setting up a mirror. Or your replacing a disk etc.
    Those are circumstances when it realises the disks are out of sync.
    Once it has a mirrored pair, it will keep them in sync since all writes will go to both sides.
    And reads take alternate blocks from both disks.
    So if the the two sides of a mirror have gotten out of sync, you will see strange results as half your content will come from one and half your content will come from the other. Even inside a single file, assuming the file is bigger than the stripe size.
    So anything writing to one side of the mirror outside of SVM's control will corrupt things. And SVM has no mechanisms for detecting this and "fixing" things up.
    So its vital to break the mirror if your going to be writing to the disk outside of SVM control.
    If your brave and the amount of changes is small, you can try to edit both sides of the mirror.
    But you have to remember that SVM works at the block level, not the filesystem level.
    So if you do anything to make the two sides even minorly different. Even something as miror as update 2 files in a different order.
    Then the layout of blocks on the disks in the 2 halves could be different. And your're screwed.
    So don't do it on any system you care about. Its really easy to make a mistake and the consequences are usually catastrophic.
    When in doubt break the mirrors. Its the only safe way.

  • Solaris Volume manager

    Hi,
    Hi,
    We are in process of developing a backup utility (CLI) using the Raid manager (Firmware operating at device level).
    Requirement
    When the user gives a mount point for backup
    -     Get the disk information that is mounted at the given mount point, if the mount point is for a metadevice then get all the disks under that metadevice.
    -     Execute the Raid manager command for disk level copying for the disks that are mounted (Primary disk) to the other disk (secondary disk), which also can be under a metadevice.
    -     Assign a backup ID, used for restoring the same when user wants
    Problem
    When a disk level copy operation is performed from a primary volume to a secondary volume which are configured by SVM, is there any way in which it is possible to configure the secondary (which now has the same data of primary) under SVM without any loss of data?

    A new feature of Solaris Volume Manager will provide the ability to import DiskSets. It should be available in a latter update release of Solaris 9.

    Unfortunately, this is a bug in the Sun jumpstart process.
    You will have to install the same packages in a postinstall phase.
    This bug has been there for years.
    It is fixed in the latest Solaris 9 cdroms dated 09/04.
    I know of no other fix except the latest cdroms.
    It is also fixed in Solaris 10.
    Solaris 8 even the most recent cdroms have the bug.
    This bug only appears in a jumpstart. It works fine in a cdrom install. I haven't investigated why the jumpstart from a jumpstart server fails, but installing the package in a postinstall phase works.
    I recommend that you download the latest Solaris 9 cdroms if it is Solaris 9 that is having the problem. For Solaris 8, postinstall phase is your only option.
    I don't remember this bug in Solaris 7.

  • Solaris volume manager and RPC

    I'm trying to run as few services as possible? Does anybody know if there are dependencies between Solaris Volume Manager (formerly DiskSuite) and rpc? I know that Solaris Volume Manager uses something called rpc.metamhd, but I'm not sure if this requires the full blown rpc.

  • Solaris Volume Manager or Hardware RAID?

    Hi - before I build some new Solaris servers I'd like thoughts on the following please. I've previously built our Sun servers using SVM to mirror disks and one of the reasons is when I O/S patch the server I always split the mirrors beforehand and in the event of a failure I can just boot from the untouched mirror - this method has saved my bacon on numerous occasions. However we have just got some T4-1 servers that have hardware RAID and although I like this as it moves away from SVM / software RAID and to hardware RAID I'm now thinking that I will no longer have this "backout plan" in the event of issues with the O/S updates or otherwise however unlikely.
    Can anyone please tell me if I have any other options?
    Thanks - Julian.

    Thanks - just going through the 300 page ZFS admin guide now. I want to ditch SVM as it's clunky and not very friendly whenever we have a disk failure or need to O/S patch as mentioned. One thing I have just read from the ZFS admin guide is that:
    "As described in “ZFS Pooled Storage” on page 51, ZFS eliminates the need for a separate volume
    manager. ZFS operates on raw devices, so it is possible to create a storage pool comprised of
    logical volumes, either software or hardware. This configuration is not recommended, as ZFS
    works best when it uses raw physical devices. Using logical volumes might sacrifice
    performance, reliability, or both, and should be avoided."
    So looks like I need to destroy my hardware RAID as well and just let ZFS manage it all. I'll try that, amend my JET template and kick of an install and see what it looks like.
    Thanks again - Julian.

  • T400 - Accidentaly formatted the disk 1 (IMD-0) partition in disk management - Help Needed

    Hello,
    Initially when I re-formatted my computer to get rid of the factory image, I found that there was a hidden partition of 1.37GB which I could not touch, meaning i could not delete. I ignored it at that time and formatted my computer and reinstalled vista business on it using the license i got from lenovo. Now after some days, I was kind of getting concerned as to what exactly was the 1.37Gb partition on my computer. I guess I was getting worried as to why I was not able to reclaim that space for normal use. Today, I tried to reclaim it, by deleting the volume, thinking it should merge into the unallocated space, that I have on my primary hard drive. But it did not. However, what happened was that this space of 1.37GB did start showing up on My Computer, once I formatted it using NTFS. I then checked its properties in My Computer and it had an option of readyboost. I selected the option which says use this disk for readyboost, and immediately in no time, the disk was full with on 68MB remaining as free space. It also has an icon of readyboost in the drive, when I double-click it. This is when I figured that this space could be on a separate physical disk. I did some research and found out that this drive or device or chip, is listed as Disk-1 in disk management and as IMD-0 under Disk Drives in Device Manager. I googled about it, and found that it was related to the turbo memory. Now, I believe that turbo memory would be a separate flash chip, which would be hardwired to function in a particular way (enabling boosting speeds), and that it would be non-accessible to users from within windows for formatting or doing anything else. Hence, I also believe that the space which I reclaimed, is existing on my primary 320GB hard drive and is used in addition to the turbo memory, as a  cache, to boost speeds. However, since I do not understand the turbo memory concept very well, I would really appreciate if someone could explain how the turbo memory works, i.e. including IMD-0 and all that. And the main help I need is on how to hide the 1.37GB partition again, and put it in a format that it was earlier in, and usable for turbo memory. At present I do not know if it is being used by turbo memory or not, but below is the current status of the turbo memory:
    1. In Device manager, under disk drives, IMD-0 shows up, and in properties it just says device type -- disk drive. Now I read somewhere that it should say NVCACHE, but it does not say that on my pc, under any tabs of the properties of IMD-0. Can someone help me putting it back there.
    2. Under Disk Management, it says Local Disk H:, 1.37GB NTFS, Healthy (Active, Primary Partition). I don't exactly remember, but I guess prior to me formatting it, it said unallocated. Help needed here too.
    3. In the Turbo memory controller, it says Windows readyboot enabled, Windows Readydrive enabled, 2GB
    and below that I have checkboxes for enabling windows readyboost and readydrive checked.
    So guys, can please anyone help me in re-hiding the 1.37GB partition and making it in the state it was before.
    Thanks a lot for your help.

    works fine.
    i insert this line in vfstab:
    /dev/md/dsk/d4 /dev/md/rdsk/d4 /d4 ufs 1 yes -
    now after a reboot the system hangs in maintanance mode and want a fsck . after a fsck and control+d
    the system coming up. after a next reboot The same Problem... !!
    without any problems i run two mirror disksets / and /var on d0 and d3 and the swap on d1.
    is it a problem with the size of 101GB on the raid5 (A5100)
    yes i know i can run veritas volume manager on the A5100 (a license is on the machine) but i was not able to install the vm bacause the vm cant find the A5100 and the license. So please help me .

  • Solaris volume manager changing raid0 stripe interlace size (-i 1024)

    Hi,
    I have 2 volume manager raid0 stripe volmes (d61 & d62) which are mirrored (d60 - see below), when the submirrors were created we ommited to increase the interlace size (-i 1024), can i metaclear d61 and recreate with -i 1024 and reattach/resync and then metaclear d62 and recreate with -i 1024 and reattach/resync?? i.e during the transition i would have one half of the mirror with 1 interlace size and the second half of the mirror with a different interlace size or is it best to backup the volume and recerate the whole stripe/mirror volume and the restore the data.
    Thanks in advance

    Hi,
    Sun support confirmed that you can have the 2 halfs of the mirror with different interlace sizes, this obviously is not the optimum setup, but will allow me to detach d61 and recreate with correct interlace size, reattach d61 and let it resync, then detach d62 and recreate with correct interlace size and finally reattach d62 and let that resync
