Hammer & Screwdriver How to backup (create image) SunOS 5.10 sparc?

Hello guys! I'm a newbee in Solaris systems.
There is an issue, that I've got:

I have to make an iso image of my solaris system.

How can I do it? with dd utility?

Clonezilla does not support spark, so it cant do backup.

pls help!

Is this solution:
Creating a Solaris Flash Archive - Oracle Solaris 10 9/10 Installation Guide: Solaris Flash Archives (Creation and Installation)
the only one method to create image of system?


tnx in advise.

Is the purpose of this solely for backup? Or is there some other motive?

What type of filesystem(s) do you have? UFS or ZFS? and how many?

Flash archive is surely a portable format which can be used for recovery, even to dis-similar hardware.

Do you have another network node that you could send a backup to?

I need to "copy/clone" one server to another "same" server, with the same options

You have mirrored UFS filesystems and you want to clone the system.

How much Solaris experience do you have?

I have recently given extensive advice/assistance to another member wanting to clone a Solaris 9 system and this will equally apply to Solaris 10.

So read these threads first and post any questions you have. How easy this will be for you will depend on your prior knowledge.

In this order:

Ufsrestore

Ufsrestore on SunBlade 2500

Partition Sizes

Park yourself beside a coffee machine and keep reading. Search this forum for your further questions and post back here if you can't find the answers.

Dear hicksd8. Thank u very much for ur efforts to help me! Actually I am a newbee in SunOS.

Even more, I have simple problems with mounting an external hdd to SunOs.

I've connected removeble NTFS 500gb hdd:
Code:
 # rmformat -l
Looking for devices...
     1. Volmgt Node: /vol/dev/aliases/rmdisk0
        Logical Node: /dev/rdsk/c1t0d0s2
        Physical Node: /pci@1e,600000/pci@0/pci@1/pci@0/usb@1c,3/storage@1/disk@0,0
        Connected Device: WDC WD50 00AZLX-08K2TA0   0107
        Device Type: Removable

trying to mount it:
Code:
mount -F ntfs /dev/dsk/c1t0d0s2 /mnt/usb
mount: Operation not applicable to FSType ntfs

ok, that makes sense...
Trying to format it to UFS:

Code:
 # newfs /dev/rdsk/c1t0d0s2
/dev/rdsk/c1t0d0s2: Device busy

hm...ok... trying to clear the old MS cruft:

Code:
 # dd if=/dev/zero of=/dev/rdsk/c1t0d0 bs=2048 count=10
10+0 records in
10+0 records out

 # rmformat -F long /dev/rdsk/c1t0d0s2
Formatting will erase all the data on disk.
Do you want to continue? (y/n)y

ok, nice...lets try again:
Code:
 # mkfs -F pcfs /dev/rdsk/c1t0d0s2:c
/dev/rdsk/c1t0d0s2: Device busy

 # newfs /dev/rdsk/c1t0d0s2
/dev/rdsk/c1t0d0s2: Device busy

Code:
# fdisk /dev/rdsk/c1t0d0
fdisk: /dev/rdsk/c1t0d0 must be a raw device.

 # fdisk /dev/rdsk/c1t0d0s2
fdisk: Cannot open device /dev/rdsk/c1t0d0s2.

 # fdisk -B /dev/rdsk/c1t0d0s2
fdisk: Cannot open device /dev/rdsk/c1t0d0s2.

# fdisk -W - /dev/rdsk/c1t0d0s2
fdisk: Cannot open device /dev/rdsk/c1t0d0s2

fdisk command does not work as well. says, that I need a raw device


ok, wanna to create slices:

Code:
# format
Searching for disks...done

Firstly, I appreciate why you are trying to connect an external HDD but do you realize just how slow it might be? If your (Sun) hardware is USB1 then it will be hopeless!! If it's USB2 it will be better but not fast and I doubt you have USB3 which would be ideal.

Having said that......

Secondly, from what you've posted I reckon that the volume manager is getting in your way and interfering with USB operations. So let's shoot that down because I doubt it's needed for anything else. On Solaris 10 as root that is:

Code:
# svcadm disable volfs

You've obviously done some highly relevant research and you have the right idea. Try again with rmformat (to find the device node once you've plugged the USB drive in), fdisk to delete existing/create new partition, and newfs to write down a new filesystem.

Try again to do all that once you've stopped volume manager messing up your life.

EDIT: You may not see the external HDD listed by format. Don't worry about that.
