UFSDUMP help
Hi
Sorry but i'm still new to Sun.
Actually, my problem here is that i couldn't backup the root file system to tape using the ufsdump command:
ufsdump 0fu /dev/rmt/1 /dev/rdsk/c0t0d0s0
DUMP: Writing 32 kilobytes records

DUMP: NEEDS ATTENTION: Cannot open 'Oracle:/dev/rmt/1cbn'. Do you want to retry the open?: ("Yes" or "No") no
DUMP: The entire dump is aborted.
I checked the tape status:
mt -f /dev/rmt/1 status
/dev/rmt/1: No tape loaded or drive offline
* I even tried with other options but return the same output. e.g /dev/rmt/1cbn
Here is the output when i scan for the tape device:
/usr/openv/volmgr/bin/sgscan tape
/dev/sg/c0t1l0: (/dev/rmt/1): "QUANTUM DLT8000"
/dev/sg/c2t4l0: (/dev/rmt/0): "HP C1537A"
I'm trying to backup to QUANTUM DLT8000. Please help.
Would be glad and appreciate with all the help given.
Thanks.
A word of caution, it is generally not a good idea to ufsdump(1M) a mounted filesystem. Not only that you may ended up with a corrupted dump, there may ended up with other side effects, e.g. hanging the filesystem in particularly ufs logging is enabled.
Possible solutions are: 1) Boot up from CD/network and ufsdump the root FS, or 2) configure UFS snapshot (fssnap(1M)) and backup the snapshot.
Hope this helps.
Regards
S.T.

Thanks.Make sure you can rlogin to the aix server as root. If you can't then that's why it failed. You may have to create a .rhosts file in roots home and modify the /etc/hosts.equiv file so that you can rlogin. After root can rlogin give it an other try.

Basically I am planning to take my production backup so any help should be highly appreciable.
ArchisHi Archisman,
There is a confusion in the questionaire you have got and the way ur performing the actions.
Can u highlight your exact requirement and expectations stepwise.
Like which all FS needs to be backed up and devices you will use etc. -
Backup issues (ufsdump/ufsrestore) under solaris 10
Hello all,
We are in the process of migrating to Solaris 10 from Solaris 8.
On our Solaris 8 systems with 2 HDDs we have a script that does a full backup of one disk (slice by slice) on to another using ufsdump/ufsrestore + boot record. The idea is that if one disk becomes corrupt logically/physically we can boot off the backup disk and continue using the system.
This worked fine under Solaris 8. We tried to do the same under Solaris 10 and noticed some unexpected behaviour when we tried to boot off the backup disk. Solaris 10 started "reconfiguring services" just like it does it when you install the OS fresh with the message:
Loading smf(5) service descriptions: xx/117
Somehow Solaris 10 "knew" that it was booted from a different device than last time.
My question would be: how does Solaris 10 know this and could we "fool" it into thinking that it was always installed on a backup disk, so it doesn't reconfigure itself every time new backup is made (and used)."... The real question is "how can I be sure that except smf there is nothing else in the OS affected by HDD change" and that is what I meant..."
The fact that you use ufsdump on mounted (I am guessing that you are doing so :-) file systems is risky!. Alternatively, you can create snapshots (fssnap(1M)) for the file systems that you are going to ufsdump on.
If your main aim is to replicate and reduce down time in case of root disk failure, a better solution is make use of mirriong via Solaris Volume Manager (aka SDS or md(7D)). Mirror does not guard against human errors though, such as accidentally deletion of crucial files :-) (which a backup strategy can guard against).
Hope this helps.
Regards,
S.T.Chang -
We do a backup daily via a script of the our zone using ufsdump.Sometimes the backup goes through each file system and other times the entire process is repeated three times.
I have also checked that there is no instruction entry specified in the script to try again if the backup should fail for some reason. Any help will do.It depends on what file systems you are backing up. Perhaps you have a backup from the root file system on down, which would include the zones. Or, say for example you use /export/home for your zones and you backup /export/home on a regular basis; that job would also include the zones underneath.
ufsdump is not zone-aware in the sense that it will read zonepath settings and treat them as separate filesystems. It might simply be that some of your jobs are redundant. -

i am a real dummy to solaris and in need of help.
I have a dump file, an oracle cold backup taken with ufsdump command. This dump file resides on the disk, not the tape.
I want to extract this dump file to a directory. But i cant, i read about ufsrestore command and i think it can only restore from the tape?
What can i do to extract this dump file? thanks in advance.Do you need the entire contents?
# cd /where/to/restore
# ufsrestore rf /path/to/dumpfile
Do you need only some of the contents?
# cd /where/to/restore
# ufsrestore if /path/to/dumpfile
restore> (add files/directories you want to restore, then 'restore' to restore them)

I have three V440�s now connected on the same network. I need to back up the data on each of these systems. I have one tape drive, a Quantum superloader3 with an ATO3 tape drive connected to one of the systems. I have in the past backed up data to a tape that resided on the same system the tape drive was attached to, but I have never needed to back data that was on another system before. At the moment I am looking into some software solutions but I now only have the basic UNIX tools to work with (mt, cpio, tar, etc.).
At the moment I am experimenting with sharing out the directory on the other system and creating a mount point on the system with the tape drive. I am using the cpio command to copy the data to tape but that is on the slow side. I have about 100 gigs of data on each system I would like to backup fully, at least once.
I would appreciate it if you have any suggestions on how I could accomplish backing these systems up. I am not particular in which command to do the backup, I just would like to be able to back them up in the shortest period of time.
I appreciate any help you can give me on this matter.I was thinking of using the ufsdump command but I did not know if it would work since I want to backup the file systems on another system.
Since in the ufsdump command it refers to the file systems by their disk slice with its full path name how do I get the command to backup the files systems on another system? -
I get this error evertime i try to ufsdump, i forgot the cause of this but I think it has something to do with blocksize, but i dont recall, please help.
sjcfwb01 $ ufsdump 0uva filesystem_root.$$ /dev/rmt/0n
DUMP: Warning - block 16 is beyond the end of `/dev/rmt/0n'
DUMP: Warning - super-block on device `/dev/rmt/0n' is corrupt - run fsck
DUMP: The ENTIRE dump is aborted.The last argument (/dev/rmt/0n, the tape device) looks
wrong. Ufsdump expects the device or the filesystem it
should dump as the last argument. ufsdump attempts to
fine a "UFS" filesystem on the device "/dev/rmt/0n" and
try to write a backup of it on the default tape device
(which happens to be /dev/rmt/0). That can't work.
You probably need something like
ufsdump 0uvfa /dev/rmt/0n filesystem_root.$$ /opt
to backup the /opt filesystem on device /dev/rmt/0n,
verify the backup and archive a table-of-contents in
filesystem_root.$$
Btw: the "v" verify option only works on "read-only" mounted
or unmounted filesystems. -
Ufsdump and restore over a networks
hi im a beginner of unix i want to know how to dump a workstation root and home partition in the server in the network or different location using ufsdump command inorder to restore it in a defferent location using ufsrestore command..im using nfs and solaris 8.because this is my problem our workstation is working and the other workstation got broken and i want to dump a working workstation not physically connect the hard disk in the working workstation..i will dump it in my office.over a network
please help me..this is useful for me cause this is always happen when workstation have powerfailure or not shutdown properly..
thnksCreate two shares on the nfs server and share it out across the network.
On the workstation that you want to use as your ufs image, mount that share point on the workstation, say /restore_root and /restore_home
mount nfs_server:/share_dir /restore_root
mount nfs_server:/share_dir2 /restore_home
Issue the following command (the assumption is that root is on slice 0 and home is on slice 3)

All dumping process were successfully done EXCEPT at /dev/rdsk/c0t0d0s3. It said that this partition is not in ufsdump format. I think because this partition is used as metadevice database.

Afte install bootblk to c0t1d0s0, we tried to boot system using clone disk result (c0t1d0). We unplugged the original disk, and put the clone disk into target 0 slot (c0t0d0).
While booting, it said that the meta database was broken and need to be repaired. we delete the metadb and re-create again --> # metadb -a -c3 -f /dev/dsk/c0t0d0s3.
then REBOOT.
But, after it, system won`t boot. the said that
*"/dev/md/rdsk/d100" = no such device or address*
*/dev/md/rdsk/d100 /dev/dsk/c0t0d0s5 /dev/dsk/c0t0d0s7 = can`t check file system*
please run fsck manually"
we have run command "fsck". but the problem still there. System can`t boot. :-(
But, while we put the original disk back, the system can run normally.
Is there any steps that we are missing? Kindly need your help, please....we stuck. No idea...please response
Thank you for any help and suggestion

FileSalvage is an extremely powerful Macintosh application for exploring and recovering deleted files from a drive or volume. FileSalvage is designed to restore files that have:
* been accidentally deleted.
* become unreadable due to media faults.
* been stored on a drive before it was re-initialized/formatted.

Hi All,
I've been trying to perform a backup of my system server for another system. My initial problem was that the other system's server is a Sun V440 while mine is a Sun V480, thus, the disk has a different SCSI connector than mine. I discovered that one of my workstations (Netra 1405) has the same style SCSI connector as the 440 disk, so I've been attempting to perform the backup with the other system server's disk in Bay 1 of my workstation.
The two drives are also a different model and size, so I've been using the format command to adjust the partitions accordingly in an effort to make them mirror my disk. Once I adjust the label and write it to the disk, I'll newfs the newly created partitions.
Next, as root on my system server, I'll issue the following: ufsdump -0f workstation:/dev/dsk/cxtxdxsx /dev/dsk/cxtxdxsx | ufsrestore -rf workstation:/dev/dsk/cxtxdxsx
*the x's correspond to the target, slice, etc of the disks I'm using
The dump will execute but will display the message "volume is not in dump format." After the dump finishes ~20min or so, I'll issue a format command on rws3 to check out the disk, and it says "<disk formatted> label?" I'll enter yes, and the partition tables come up, but they're all changed around from what I initially configured. I can't mount the newly dumped-to partition either. Is the syntax of my command correct? Should I try to dump to the raw device? Do both servers have to be running the same version of Solaris? -- please advise.
One more concern, just dumping data to the disk partitions does not make a golden disk. I did some research and found a command /usr/sbin/installboot that can be used to install a boot block to a newly cloned disk. Is this something I'm going to be able to do remotely from my system server to my workstation as well? -- or will the other system just have to insert the disk into their server and install their boot block from there?
I greatly appreciate any help,
DaveNext, as root on my system server, I'll issue the
following: ufsdump -0f workstation:/dev/dsk/cxtxdxsx
/dev/dsk/cxtxdxsx | ufsrestore -rf
workstation:/dev/dsk/cxtxdxsxWhat do you intend this command to do?
You are giving ufsdump a remote filename, but then pipe it into ufsrestore. Since the filename is remote, there's no data for the ufsrestore to read.
It doesn't work like that.
Your best bet would be to assume that you have ssh (or rsh) between the machines:
serverA# ufsdump 0f - /<filesystem> | ssh serverb "cd /<newfilesystem> && ufsrestore rf -"
The dump will execute but will display the message
"volume is not in dump format." Actually, that's ufsrestore saying that. Note that ufsrestore always restores on the local machines. So it looks to me like you're trying to send a dump image to a workstation, then run ufsrestore to read the data from the remote workstation and restore it locally on the server.
After the dump
finishes ~20min or so, I'll issue a format command
on rws3 to check out the disk, and it says "<disk
formatted> label?" I'll enter yes, and the
partition tables come up, but they're all changed
around from what I initially configured.ufsdump doesn't manage partition tables. Never stick a dump image on a raw device like that if it has cylinder zero or you'll corrupt the label.
ufsrestore must already have the filesystems sized, created, and mounted before it can work.
I can't
mount the newly dumped-to partition either. Is the
syntax of my command correct? Should I try to dump
to the raw device? Not unless you're doing something very special, and I don't think you are.
Do both servers have to be
running the same version of Solaris?No.

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.

Duplicate fiber root disk using just ufsdump/ufsrestore/installboot ...
I have to setup 5 x 890 servers and 4 x 490 servers. Without using jumpstart, is there a quick way to do a duplicate a root disk using just ufsdump/ufsrestore/installboot commands? If these boxes had SCSI drives, this would not be problem. Because of the fiber drives, I am struggling to figure out how to do it - because the WWNs are embedded into device tree.
Anybody got any ideas how to do it using plain old ufsdump/ufsrestore commands?
Thanks.
SGHi Michael,
Thanks for the qucik reply.
The problem persists. I deleted the contents of /disk2/dev/dsk and /disk2/dev/rdsk. Then I rebuilt the device tree using:
/usr/sbin/devfsadm -c disk -r /disk2 -p /disk2/etc/path_to_instThen I set the boot parameter:
luxadm set_boot_dev /dev/dsk/c2t2d0s0When rebooting, the new WWN now correctly shows up under boot-device. However, the file system appears to be mounted as read-only again. The same errors show up on the screen, all related to starting services, cron, etc. All instances are followed by an error message of "Read-only file system".
I also fsck'ed the root partition, but this didn't help fix the problem.
After this test, I ran fsck again, and noticed that c2t2d0s0 was last mounted on /disk2, so the root slice was in fact never mounted during boot.
Is there anything else I can check with regards to the read-only mounting problem?
Thanks. -

That one's from a book. I used that code to start with my applet. Mine calls different merthod from the switch cases. Say I have:

/* something here */
drawMain(g);
public void drawMain(graphics g){
g.drawString("test", x, y);
//here's where i'm trying to pause
//i've tried placing Thread.sleep between these lines
g.drawLine(x, y, a, b);
//Thread.sleep here
g.drawRect(x, y, 50, 70);
}I also need to put delays between method calls but I need to synchronize them. Am I doing it all wrong? The application pauses or sleeps but afterwards, it still drew everything all at once. Thanks a lot!It is. Sorry about that. Just answer any if you want to. I'd appreciate your help. Sorry again if it caused you anything or whatever. .n_n.
