Remote tape drive

I have system taht only has a tape drive attached to the SMC. Can you use a remote tape drive under solaris 10? do you nfs the tape drive? how do you connect to a remote tape drive?

Well, when you boot a machine into single user mode from a CD or DVD, it will not automatically configure the network, but you can do this by using normal ifconfig commands.
Before doing the restore you will have to create a new filesystem on the disk by runnings newfs and then mount it as /a or similar .
You can perform an ufsrestore from a remote machine by specifying the remote machines tape drive as the path to restore from, e.g.:
ufsrestore if <user>@<remote server>:<tape device>
for example, to do an interactive restore from a remote tape::
ufsrestore if admin@remote-server:/dev/rmt/1
.. one drawback with this is that ufsrestore probably rely on rsh to communicate with the remote server, so you might need to enable rsh and configure a .rhosts file for the user.
You can probably pipe the tape over ssh as well, with something such as:
ssh <user>@<remote-server> "dd if=/dev/rmt/1 ibs=1024" | (cd /a ; ufsrestore xf -)

  • Ufsrestore root filesystem from remote tape drive

    If disk is replaced and I want to restore root filesystem, should I be able to access a remote tape drive to do this?
    i.e when I do
    boot cdrom -s, should I be able to access the nework? Or is that not posible with root filesystem installed?

  • BRtools Two-Phase-Backup to remote disk and remote tape drive

    Hello,
    i want to two-phase-backup a SAP-System to a remote disk and from there to a tape drive.
    Backup to remote disk works fine, but can i use brtools to write the backup-files from the remote machine to a tape drive that is connected to the remote machine?
    I'm using SLES 10 on both machines.
    I can't find anything on the SAP Documentation to this. It ist possible to backup to remote disk and to remote tape, but it is not clear that it works when in Phase 1 of the backup the files are written to a remote disk. It seems like i can only tell brtools to backup the files from a local disc to a remote tape-drive, is this right?
    Thanks in advance for your help.
    Regards
    Phil

    Hi Nirmal,
    thanks for your answer.
    But i can do disk to tape Backups, when i choose "Backup of Disk Backup" from BRtools, i see a list of all Backups i wrote to the local disk and can write them to remote tape by using pipe as backup device.
    The only thing is, my Backups are stored on a remote disk, and from there it seems i have to write them to tape with cronjobs using a shell script. That's not my favourite solution, but it's ok.
    Regards

  • Ufsdump to remote AIX tape drive

    I am trying to ufsdump to a remote tape drive that is on an AIX box.
    I have configured the /.rhosts file on the AIX server
    I have created a symbolic link /etc/rmt to point to /usr/sbin/rmt on the AIX box
    I am running the following command on the sun box
    ufsdump 0cuf AIXBOX:/dev/rmt0.1 /dev/dsk/c1t0d0s0
    but I get this :
    DUMP: Date of this level 0 dump: Thu Feb 18 15:42:17 2010
    DUMP: Date of last level 0 dump: the epoch
    DUMP: Dumping /dev/rdsk/c1t0d0s0 (SUN10:/) to AIXBOX:/dev/rmt0.1
    DUMP: Mapping (Pass I) [regular files]
    DUMP: Mapping (Pass II) [directories]
    DUMP: Writing 63 Kilobyte records
    DUMP: Estimated 12017946 blocks (5868.14MB).
    DUMP: Lost connection to remote host.
    DUMP: Bad return code from dump: 1
    DUMP: Date of this level 0 dump: Thu Feb 18 15:42:28 2010
    DUMP: Date of last level 0 dump: the epoch
    Is it possible to get this to work?

    If i interpreted the code to ufsdump correctly, it will attempt to execute the command /etc/rmt on the remote host over a shell (port 514) connection.
    The rmt supports the remote magtape protocol, so ufsdump creates a datastream and sends it over the network to rmt, which is responsible for sending it to a tape device.
    Is there an /etc/rmt binary in AIX? In Solaris there is a /etc/rmt, even if its just a link to /usr/sbin/rmt, if there isn't a /etc/rmt, check if there is an rmt binary elsewhere on the system, and symlink it.
    If there is a /etc/rmt, two other things to check would be that the shell connection is working (by running something like 'rsh AIXBOX echo hej') and double check the path to the tape driver on the AIX host.
    Hope this helps, i am not that experienced in remote taping nor AIX.

  • Restore Root Filesystem - Remote Tape?

    Hi there,
    Does anyone know of a way to restore a root fs from
    a remote tape drive? The usual method seems to be to boot into single user mode off the cd but obviously you don't get the network this way.
    Is the only viable way to have the tape connected directly?
    Any ideas would be appreciated,
    Thanks in advance.

    The usual method seems to be to
    boot into single user mode off the cd Yep.
    but obviously you don't get the network this way. Why not?
    I'm sure the (GUI) installer on the Solaris Installation CD will
    configure the network interfaces and naming services first,
    before the installation starts.
    After that step has completed, you could start a terminal window
    and there should be a usable network configuration, for restoring
    from a remove tape drive.
    With a rarpd and bootparam server on the same ethernet
    segment, the configuration of the network interface should
    even happen automatic.
    And if all else fails, it shouldn't be too complicated to "ifconfig plumb" the network interface, manually configure the ip address,
    then use the network:
    ifconfig dnet0 plumb
    ifconfig dnet0 inet 192.168.1.2 up
    rsh -n 192.168.1.3 dd if=/dev/rmt/0 bs=32k | ufsrestore -xf -

  • Tape drive  and pci-x card  with Solaris 10 on  VMWare environment

    I have a Sun X4170 server (x84_64) running VMWare ESXi 4.0. On it I have two VM guests- my production file server running Solaris 10 U7 and a test file server running Solaris 10 U9.
    The X4170 has a PCI-X LSI Logic dual external U320 parallel scsi card. I have a tape drive + auto loader cabled to the X4170. It is a Quantum branded autoloader but I believe the tape drive itself is HP. The autoloader+tape drive share a single SCSI ID (6) but have separate LUNS.
    I have two choices for making this system accessible to the OS:
    -     Virtualize the tape drive and loader individually.
    -     In VMWare, enable the scsi card as a pass through device. The SCSI card is then added as PCI device to the virtual machine (actually two devices since it is a dual scsi card.)
    I had virtualized a single-drive tape drives with Vmware in the past.
    However, when I tried I virtualize tape drive and loader, Solaris complained about the scsi id’s being invalid. I don’t think it likes two devices with a single scsi ID. Also, I think I need the backup software to see the REAL tape drive and autoloader (for inventory, changing tapes etc)

    Any ideas? Maybe a need to update the MPT driver or is that dangerous?
    Thanks

    Actually, updating the kernel patches (and enabling hot plug service) did solve the problem. At some point during between testing the system before and after patching, the tape drive got turned off. Since the system patching was being done remotely it was not immediately obvious that the tape drive was off.

  • Tape drive reconfigure

    Hi all,
    i am presently running a server that has no video card. No problem to access it because a use rlogin to manage and maintain the server.
    Now i need to reconfigure the server to "see" the new tape drive i installed.
    One way to reconfigure the server is to use the OK prompt with the STOP-A keys. But that works only locally, not on the remote host.
    Is there a way to reconfigure the server by remote access?
    Thank you

    Thanks for the info. According to the following manual (caution it's a pdf), on pdf pages 31 & 32 of 149 ( manual pages 1-19 & 1-20) it is not hooked up exactly as specified but this shouldn't be a problem.
    They have the terminator on the AutoLoader. You have it on the drive.
    http://sunsolve.Sun.COM/handbook_pub/Systems/L9/documents/L9_svc.pdf
    The question I have is where is it connected to the E250? Did you have an HBA (Host Bus Adapter or SCSI controller) installed to support this L9. Depending on the drive installed in the L9, (DLT8000 vs DLT1) You would need the proper controller installed in one of the PCI slots in the E250. See:
    http://sunsolve.Sun.COM/handbook_pub/Systems/L9/components.html
    Also, if this is a DLT8000 drive in the L9 then you may want to load the latest st.conf patch to enable DLT8000 support in the /kernel/drv/st.conf file. Just search for st.conf in Free Patch Descriptions in SunSolve. Use the appropriate patch based on the Solaris version you have installed.

  • Backup Tape/Drive storage

    Forever is a long time and no medium will meet that requirement.  Most financial data has to be stored for  < 10 years.  A lot of things change in 10 years, including tape drive technology.  You need to consider starting tape museum (keep functional tape drives and software including peripheral cables.)  You need to consider how you will validate the tapes are working and you are able to read data at set interval.  You may also consider AWS Glacier, technology developed to address your exact requirement.
    Tapes are good for long storage but they the have to be stored properly, temperature and humidity levels are critical.  Consult recommended guidelines for the tape brand you purchase.

    Hi, I am looking to get ideas on what you all might use to store your backup tapes and drives onsite or at a remote location. I don't have the option of using an Iron Mountain or 3rd party to do the storage so I have to store all of them and finance wants me to store them forever. So, I might have stacks and stacks of drives.
    Any recommendations for cabinets or cases or ?
    Thanks!

  • Using ssh to do remote tape backup

    I tried to setup a remote tape backup from ServerA to ServerB. The Tape drive is attached to ServerB. I had looked up some document how to setup "no password" login for root using ssh. Both servers had exchange their root public key.
    When I tried the command "ssh ServerA ls" from ServerB, it showed me the ls of the "/". I was also able to do the same thing from ServerA.
    However, it gave me access deny when I tried to do the following backup command from ServerA
    ssh ServerB "/usr/sbin/ufsdump 0uf ServerB:/dev/rmt/0un /dev/rdsk/c0d0t0s0"
    Can someone tell me what I had missed in setup the ssh, or is there any problem in the backup command. In my mind I just treated the ssh as rsh when I issued the backup command.
    Thanks in advance.

    as i understand it, you are trying to dump the /dev/rdsk/c0d0t0s0 from serverA onto the /dev/rmt0un on serverB, right?
    hmm, not sure ufsdump has the facility to use ssh. in any case...
    **NOTE -- not generally a good idea to allow a password-less login for anybody, even root from another machine; a better way would be to install sudo on the remote machine, and allow a user to be logged into without a password, but only allow that user to run a specific command as root. look up use of ssh "authorized_keys" file for more information on limiting command usage by key...
    ok. so you have data on serverA, and you're going to put it on serverB... we'll start with simple. here's a tar command to copy all the files from serverA:/backmeup to serverB:/storeme; i'll use the prompt "serverA>" to signify that we're typing these commands from serverA.
    serverA> cd /backmeup
    serverA> tar cvf - . | ssh serverB "cd /storeme; tar xvf -"
    now, you COULD use that to copy files directly onto tape...

    you may have to play with the block size tho. for that matter, i would THINK that you could do the same for you ufsdump command:
    serverA> ufsdump 0uf - /dev/rdsk/c0d0t0s0 | ssh serverB "dd of=/dev/rmt/0un"
    but you're going to have to try it to find out...

    Hello i am using TimeMachine to back-up entire Mac image (data + system) on an usb-local drive. I would like (on top of it) add a specific plan to back up some files on a remote network drive. Does TimeMachine support multiple back-up plans ? How ?

    Time Machine is capable of backing up to multiple locations, and can be used to back up to both a local hard drive and a networked drive (provided that that drive is in or connected to a Time Capsule or another Mac that is sharing it over the network). The catch, though, is that you can't specify different things to back up to different destinations. Whatever you exclude from Time Machine backups is excluded from ALL backups, and whatever is included is included on all.
    So, get a large enough drive that you can back up everything you want in all locations, or use something else for maintaining the network backup.
    More information on these topics can be found here:

    How do I set up Time Machine to a Time Capsule or Airport Extreme?

  • Voice Memos File management with wireless remote hard drive

    Dragging unwanted voice memos from within iTunes application to trash, then emptying trash, won't delete voice memos in the "voice memos" folder in iTunes Media on my external remote hard drive. Why not?
    I manage my iTunes music from my laptop, storing the actual files in an iTunes Media folder on a hard drive connected to an Airport Extreme. The hard drive was close to full and I decided the culprit was giant voice memo files. I didn't need most of them so I dragged them to the trash from within the voice memos "playlist" in iTunes. This removed them from the playlist, but even when I emptied the trash via the Finder pull down menu, the files stayed in the actual folder on the hard disk. Disk still full. What gives?

    Hi Samboni98, and a warm welcome to the forum!
    You could do that, but a far better idea would be to clone the 160 to the 500, then boot from the 500 which besides beimg faster, OSX just loves lots of Free space.

  • Error after installing tape drive

    Hi,
    I am a newbie to Solaris, I have a SunFire V120 box, i was trying to install a tape drive(HP SureStore DAT24), i did the install in this manner.
    # rm -rf /etc/path_to_inst
    # init 6
    later at the "ok" prompt i gave "boot -ar" after doing that it asked me various options i accepted the default values, when it asked for rebuilding the /etc/path_to_inst file i said "y", but later everything went wrong.
    This is the output,

    After doing some google i found that nothing is wrong i just need to comment some lines in the /etc/system file. But still i wasn't able to bacause the system is mounted in read only mode.
    Thanking you in advance.

    I have exactly the same problem after running an fsck to clear corrupt files.
    Is there a problem with mirrored disks and using boot -ar to rebuild path_to_inst?
    The basic problem is that the root filesystem is coming up as read only
    i.e.
    The /etc/path_to_inst on your system does not exist or is empty.
