Solaris

Hi all,
this time I'd need a help from an advanced Solaris system admin

I attached a HP StorageWorks Ultrium 215 Tape Drives - Overview - c00059530 - HP Business Support Center to my Sun E220R and it got recognized immediately (probe-scsi-all).
Now the operating system boot process finished, I logged in with root and in dmesg I can see the drive:

Code:

Feb 10 17:47:44 sunbox1 scsi: [ID 365881 kern.info] /pci@1f,4000/scsi@4/st@3,0 (st19):
Feb 10 17:47:44 sunbox1        <HP Ultrium LTO>

Code:

# iostat -x st19
                 extended device statistics                 
device    r/s    w/s   kr/s   kw/s wait actv  svc_t  %w  %b 
st19      0.0    0.0    0.0    0.0  0.0  0.0    0.0   0   0 
#

Here are the questions:
How can I read the tape content?
How can I eject it with a shell command?
Can I load an already ejected tape?
Do I neccessarily need a proper/commercial Backup Software?
Can't I simply do the backup using dd command?
How would I do a full backup of the main harddisk sd0 ?
How would I do a full restore of the main harddisk sd0 ?

Please also note this is 100% my personal hobbyist problem!
It's definately not a real-world problem and of course this is not a homework or something.

Use mt command. For that you can use tar or ufsdump/ufsrestore.

Dear bartus11,
thank you very very much for your PERFECT answer

I have all the commands you've mentioned and I'll study their man-pages.

Before I've posted my questions, I've run man st, but somehow I didn't understand anything

One more question: What if my system had a ZFS filesystem, may I also use the ufsdump/ufsrestore commands or should I rather go for tar command in that case?

BEST regards,
pc

You can't use ufsdump/ufsrestore with ZFS. I think you can send ZFS snapshots to the tape though. Check zfs(1M) man page section for zfs send and zfs receive.

I know this isnt the type of reply you were looking for but this is my first try at using a forum to answer my questions regarding Solaris. I have tried multiple times. What do I need to do to get a reply from someone on here?? If there is a rule that I am not following please let me know as I am out of options and need some assistance.

Great!

wtf?!

If you intended to help me, be sure you didn't.

If you need help, what's exactly your problem?
You posted a problem and no-one replied to it? Here? URL?
There are many written and unwritten rules.
Don't hijack others threads!!
Ensure that you post a qualified problem description, not just HELP HELP HELP.
Also post what you have tried at your own to solve the problem and so on.
Post in the right sub-forum and the like.

Good luck and start with stopping thread-hijacking!

I didnt mean to offend. If I did, I apologize. I did submit under the correct sub-forum with a very concise list of issues. I have been working on the problem on my own for the better part of a week and have been unable to correct it myself. I am always very polite and try to provide as much helpful information as I can and yet you are the first to ever reply. Again my apologies and thank you for you input.

Oh, and my issue was regarding the runtime linker in solaris ld.so.1. I know literally nothing about it and it is really wearing me out.
