NW6.5Sp8-iscsi- SLES11SP = The network disk vanishes

NW65sp8(iniciator)---iscssi-->sles11sp1(target)
Create "testvol" in the iscsi.
From the User WS (XP_sp3+nw4.91sp5 client) log in to the Netware and map:
g: = \\grad\workvolume
u:=\\grad\testvol
This is OK.
Run copy large files (*.iso). from g: -> u:
after some times (2...7 min) drive "U:" vanishes from the WS...And need recconect and run copy again...
At this time on the server I do not see any messages on an error.
Please, help me.

What you see here is a classical problem. Your storage is too slow,
which unfortunately is "normal" for Netware iSCSI. Your workstation is
using a GB connection, right? The "freez" you see is not really a
freeze, it *will* recover on it's own, but it seems frozen when the
Netware file cache is full. Your workstation writes the data faster to
the server than the disk (iscsi) can write. I'm afraid there's nothing
you can do, sorry. :(

  • Deleting the network disk

    Hello all,
    I wanted to know if there was a way to delete the network disk listed in the Startup Disk control panel?
    -Thanks.

    Hi, PSST -
    None that I'm aware of. There may be a way to do it using ResEdit on one of the system's files, but which file that is and what resource in that file to alter is not something I'm aware of.
    Changes made in Startup Disk control panel are entered in the Startup Disk Preferences file (in the Preferences folder in System Folder); I believe that info is transferred to PRAM when the machine is restarted or shut down, rather than immediately.
    If your concern is someone (accidentally or willfully) changing the Startup Disk selection to Network Disk, you can try -
    • removing the Startup Disk control panel from the Control Panels folder and hiding it (one way to do that is to make it invisible). Make sure that your preferred boot volume has been selected before removing it.
    • locking the Startup Disk Preferences file. Though this is easily undone by someone savvy to unlocking and locking files, it may suffice to prevent a casual user from changing the boot volume.

  • Airport Extreme is toast; how to read the network disk via USB?

    My Airport Extreme Base Station is toast; light is green, but it won't respond to anything and the MacBook no longer sees it. Tried resetting it; this thing is done.
    Well, as I was writing earlier, I have a hard drive connected to the Base Station I've been using for Time Machine backups. Seeing as now my Base Station is dead, I need to hook this hard drive up directly to the MacBook using USB or FireWire. Well, I've done that, and Time Machine has no clue how to access this drive. Using the "Browse Other Time Machine Volumes" does not bring up this drive.
    I have some absolutely critical data I need to reach, and it's more than frustrating knowing it's on this hard drive, yet I'm completely unable to access it... I've been good and backed up my data in case of loss, only to have the backup seem to not work at the same time.

    ...is there a way I can force my MBP to only connect to the n base station ?
    Don't use the 802.11b/g/n AirPort Extreme base station (AEBS) to extend the 802.11b/g AEBS's network. Not only must this use 802.11g for the connection between the 2 AEBSs, but that connection uses WDS which cuts your wireless bandwidth in half. So the MacBook Pro may connect to the 802.11b/g/n AEBS with 802.11n but the data transfer speed is limited to 27 Mbps.
    Instead connect the 2 AEBS's vie Ethernet and create a dual-band network. You will find threads describing this and it is also documented in Apple's documentation.

  • No windows disk in the startup disk list

    Hi there,
    I installed Windows vista on my Macbook and it works great.
    My problem is when I need to switch the OS, there are only Mac OS and Network startup in the startup disk list. The icon for windows is gone. It was there several days ago. Now what I can do is pressing down the option button and select windows every time.
    I do some search in the forum and found someone talk about resetting the PRAM.
    I followed the instruction but it does not help.
    Could you please tell me what should I do?
    Thanks a lot.

    You may not have to remove it.
    The Windows disk vanishing from the Startup Disk options is a known issue though.
    Does this help?

  • Sharing iTunes library between 2 computers and 2 iPods via network disk?

    Hi,
    Me and the missus each got a laptop -hers a PC and mine a MacBook.
    We both use iTunes and we've both got an iPod.
    Recently I bought an Aiport Express and hooked it up with a 1TB WD MyBook -is there any way that we can share our iTunes library via the network disk, so that we can 1. have full read/write access from both laptops and 2. both sync our iPods?
    Furthermore, is there a way for iTunes to monitor the music folder, so instead of me dragging music into iTunes (e.g. CD's that were ripped with other software than iTunes) iTunes would just update every once in a while, to check for new mp3's (kinda like Picasa does with pictures)?
    More questions most likely will pop up, but this is the most pressing ones.
    Thanks in advance
    /Jakob F.

    *is there a way for iTunes to monitor the music folder, so instead of me dragging music into iTunes*
    iTunes doesn't support folder watching, anything you add to a folder on your hard drive has to be manually added to the iTunes Library: Adding Content to iTunes
    You could have a look at this Applescript for folder watching on a Mac: Doug's Applescripts - Folder Actions and iTunes or this program for Windows: iTunes Folder Watch for Windows
    You'd need to do a deeper bit of research on both as I don't know if either would work from a folder that's effectively not on either computer

  • How can I store document on a network disk?

    With the old Pages I was able to store and edit documents right from my network disk (where I have full permissions on). I updated to the new version, with the big changes, and now suddenly it tells me it is unable to store the document because I apparently don't have the right permissions. I checked the network device and I got full permissions, besides all other apps don't seem to have that problem, even more specific when I boot up the old Pages I can store and edit documents again without problem. So it really seems it's something in the new Pages that is causing the problem. Also, the latest update did not address or solve this issue.
    It get's even worse. When I create a new document and store it on my own disk and then drag it to the network disk, there is no problem. When I open that document from the network disk and edit something and I try to re-save it, it tells me "I don't have permissions to store the document" and it messed up the document on the network disk from MyDocument.pages to MyDocument.pages.sb-76d48d4f-LvItH9, and instead of a file it is now a folder. This was behavior which was also not seen on the old Pages.

    Pages 5 has over 90+ missing features plus annoying bugs like this.
    Your previous Pages should be in your Applications/iWork folder.

  • Can't Reconnect to Network Disk

    I am to to Apple. When I first setup my iMac, I was able to attach to my network disk. Subsequent attempt to attach to the network disk result in a message that says the server does not support guest logins. Does anyone know how I can reattach?

    I suddenly have this problem after no changes were made to either my Mac or XP server configurations. Bizarre. None of the normal restarts or creating new users accounts is helping. Now the Mac window just displays the message 'connecting...' indefinitely.

  • Aperture 3 with Library on a network Disk

    Please, someone who have buy the full version, could tell me if Aperture 3 works with a library on the network disk. Because with the trial version it's impossible. Thanks for our reply.

    I have been experimenting with Aperture 3 and this workaround for a couple of days and I can say that Aperture 3 is pretty much useless over a network - at least in my case.
    I migrated all of my iPhoto libraries (about 33K images / 200 GB) to A3 on Mac 1. The library is on an external disk connected to Mac 1 and everything works fine on this computer. I do notice that A3 with one large library is considerably slower than iPhoto was with smaller libraries. Not too much of a surprise, but the big surprise was how differently it behaved over the network:
    - It takes 45+ seconds to load the library over Gb Ethernet.
    - None of the thumbnails show up. None of the faces in Faces show up. However, if you open the Viewer on a thumbnail, the image appears quite fast. Nothing I tried could make the thumbnails appear. Looking at the library XML files, the paths and everything look just fine...
    - Importing takes forever. I tried importing a small set of 53 images. This would take about 30 seconds with iPhoto (over the network) and after about 20 minutes, I cancelled the tasks. 5 minutes later, Aperture is still trying to cancel.
    I don't see anyway to replicate the workflow I had in iPhoto that I was hoping to improve upon using a better tool. I would run iPhoto on Mac 1 with all of the photos in libraries on an external disk connected to Mac 1. From Mac 2, I could open and use the libraries on Mac 2 with negligible speed difference compared to working on Mac 1.
    I need a configuration like this to work because my wife and I share the same libraries. I could create a library with referenced masters and somehow sync that library between the computers, but that's not what I wanted. Syncing creates a whole new set of problems...
    Any suggestions / recommendations?

  • Auto connect to network disk

    Is there a way to set the network disk connected the USB port on the AIrport extream base station to auto connect on boot up?  When I shut down the iMac or reboot the shared network disk has to be manually connected.  Any help will be greatly appreciated.

    td - thanks for the reply. i will try it when i get access to the machines again. i initially did have sharing from the Users/Shared folder, and it worked great - except if someone edited something while the library was open on another person's computer. then the database would be corrupted and would only open on the machine that just saved it (which is odd). if library is shared from this folder, will iPhoto 8.0.2 give a warning message and prevent access as the apple doc claims?
    also curious - why then does apple say the sparse format is not required, but is recommended?
    +From the Format menu choose read/write disk image or sparse disk image (recommended).+

  • Sharing iTunes library on a network disk from 2 macs on same network

    Hi all,
    I'm ready to significantly change my network to incorporate an Airport Extreme, an iMac and a MacMini. I'd like to be able to do the following:
    1. Install a network disk of 1Tb (connected with RJ45 as any network disk) to hold an iTunes Library
    2. Connect a MacMini to the network, to my home-theatre system and to my flat-panel TV and have iTunes installed on that MacMini. This iTunes would go and get the library from the network disk.
    3. Connect an iMac to the network and have iTunes installed on that MacMini. This iTunes would ALSO go and get the SAME library from the network disk.
    Would that work?
    If yes, would you have any recommendations?
    If no, how would you suggest doing that?
    Thanks.
    Alain.

    I pretty much am looking for the same answer. Until we buy an external HD to connect to our airport extreme, I am trying to have the laptop access the iTunes folder on the mac mini. I had no problem choosing the correct folder but then iTunes asked me if it was ok to move & organize the folder. I didn't like the sound of that so I cancelled.

  • User permission on SMB mounted network disk

    I have a Buffalo TeraStation automounted via "NetInfo Manager" in my G5. But only the user that I used to mount the disk, and the root user can access the mounted disk. Other users in the same machine can't get permission to the network disk.
    Does anyone know how do I add the permission for other users? Thanks!
    G5   Mac OS X (10.4.4)  

    Ok found a sollution, i tried a couple of things, it boils down to this.
    login as admin user
    1. demote the network user to a local user,
         use workgroup manager for it use export in menu to export user from LDAP
         import to Local directory, reset the password and delete the LDAP user.
    2. you chould now be able to localy login to the account, do that.
    3. open the terminal and run the following commands (probably need sudo for it and you need to change <username> to the user you want to change)
         chmod -R -N /Users/<username>/
         chown -R <username>:staff /Users/<username>
         chmod -R 700 /Users/<username>
    4. check that every thing in you're account is working again as should.
    5. promote local user to network user.
    use workgroup manager for it use export in menu to export user from Local
         import to LDAP directory, reset the password and delete the Local user.
    this did the trick for me, hope it helps.

  • Network Disk Disconecting

    Hello,
    I have a new Core 2 Duo Macbook and just bought the new airport extreme, and I love it. However, there is a small issue.
    I plugged an external hardrive into the airport in order to share my music over the network. It seemed to work like a charm. I went into itunes and I did not even have to tell itunes where to look for my music, it automatically found it.
    The problem is that after I put new music on the hardrive, and then try to add it to my itunes library, the network disk disconnects. Then, when I try to reconect it it tells me the password is wrong. I have to go back through airport setup and set a new password for the disk, and then it connects again. The disk only seems to disconect when I go into itunes and select any music to "add to library." Any ideas what is going on? Thanks.

    I will try to make this a little easier to understand.
    1. I have a USB drive plugged into my AEBS and my Macbook CD2 sees the drive just fine and all the files on the drive.
    2. My iTunes library is linked to my music on this hard drive, and all my music plays perfect in iTunes.
    3. I add new songs to this networked hard drive, then I go into iTunes and click "add to library" and then I select the new songs.
    4. The network drive disconnects without any warning. When I go to disk utility and try to reconnect the network drive, it tells me my password for connecting to the drive is wrong.
    5. To get the drive to reconnect I have to go back into Airport Setup Utility and set a new password for the drive and then I can reconnect.
    6. This happens every time I try to "add to library" new music in iTunes, and this is the only time I have any problems.
    7. I have a MBC2D with the newest os x and iTunes version and I have the brand new AEBS with the 'n' capability.

  • I loaded in Lion - but my time capsule will not back up. I get an message: couldn't complete backup due to a network prolem. Also it says "make sure your computer and back up disk are on the same network, and that the backup disk is turned on.

    I have exactly same problem with my MBP and MBA, after upgrading to Lion. I've tried to fix this issue while cheking key chain issues and network setup, even formating hdd and time capsule firmware upgrade (ver. 7.6.1.). Nothing can help. It is very annoying.

  • Several computers sharing the music library stored on a network disk: howto

    Hi,
    We currently have iTunes set up on a (laptop) computer. The music folder location is on a network disk (NAS). Everything has been working fine.
    We recently purchased two more laptops for other family members and would like to set up the iTunes for those computers to use the same existing music folder. Is this possible? I understand that we must authorize all computers using the library to be able to play purchased music.
    So far we have synced all our ipods using the one and only computer. In the future each of us will use their own laptop for syncing. Will this cause any problems regarding to the shared music library?
    I guess that the playlists are stored in the itunes files, not in the music library. Due to this the playlists must be created on the new computers after the itunes installation.
    Best regards,
    ikl

    You are most of the way there. The only issue will be that anything done by one machine will not be automatically updated to others. Files deleted from NAS by one machine will not be available to others anymore leading to ! next to track names if in libraries on other machines.
    Files added by one machine will have to be added to the libraries of the other machines using 'add file to library' or 'add folder to library' options on menu.
    Podcast subscriptions should be only files that will duplicate on NAS. Podcast subscriptions are individual to each library even if stored to same location. The files themselves well get numbered. The library will know which file to use. This allows episodes to be deleted without affecting other users.

  • HT3275 Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive.  Could not complete backup to media share.  The network backup disk does not support the required AFP feat

    Since updating OS to Mountain Lion from leopard, I get the following error message when trying to backup with time machine on external drive.  "Could not complete backup to media share.  The network backup disk does not support the required AFP features."  What are AFP features and how do I get Time Machine to backup to my current external backup?

    This means that your NAS does not support the required encryption. Update your NAS to the latest firmware or ditch it and buy a Time Capsule (they are the most reliable when using TM).
