| {column:width=55%} h1. How to access a Solaris partition from Windows or Linux |
| by Bernd Schemmer, Last Update: December 2008 Homepage: [http://www.bnsmb.de/|http://www.bnsmb.de/] *Table of contents* {toc} h1. Overview |
| This article discusses a method to read and write data from Solaris partitions from within Windows or Linux. |

| [http://www.milax.org/?page_id=9] |
| unpack the Qemu archive (there's no installation neccessary for Qemu), copy the Milax ISO image, milax03.iso, to the directory with Qemu and start a Virtual machine for Milax with the command\\ |
| {code} \\ |
| cd {code}cd <directory_with_the_qemu_binary> |
qemu.exe -L ".\bios" -m 256 -localtime -boot d -cdrom ./milax03.iso -hda \\\\.\\physicaldrive0 -net user -net nic,model=rtl8139 -redir tcp:1135::22 -name "Milax_(ssh_port:_1135)" -snapshot |
| {code}{*}Notes:* |
| *Notes:* |
The parameter "-snapshot" means "write to temporary files instead of disk image files". That means that Qemu does NOT write to the harddisk. If you want to write your changes to the harddisk to can switch to the Qemu CLI with the key combination ctrl-alt-2 and issue the Qemu command "commit ide0-hd0" any time you like (see the Qemu documentation for details). To switch back to the Virtual Machine use the key combination ctrl-alt-1. You should NEVER use Qemu with access to real harddisks WITHOUT the parameter \-snapshot\! |
... |
| You must use a double backslash for a backslash for Qemu 0.9.1 |
| The number in the parameter "\\\\. \\ |
| The number in the parameter "\\\\.\\physicaldrive0" physicaldrive0" specifies the disk to use - if Solaris is not on the first harddisk replace 0 with the approbiate number. |
This syntax works on Windows XP (tested) and should work Windows 2000 also. There are messages in the Qemu forum that this syntax does not work in Vista - I can not check this because I do not have Vista. |
... |
To access the Virtual Machine from your Windows host use |
| {code}ssh -l alex -p 1135 localhost {code}or with scp {code}scp -p 1135 alex@localhost:/etc/release . |
| {code}{*}Notes:* |
| ssh -l alex -p 1135 localhost {code} or with scp {code} scp -p 1135 alex@localhost:/etc/release . {code} *Notes:* |
I've only tested this with Qemu 0.9.1 - this may or may not work with older Qemu Versions. |
... |
Use dmesg to list the device names for the Solaris slices: |
| {code} |
| {code}root@tp61p:~# dmesg | grep sda |
[ 23.652384] sd 2:0:0:0: [sda] 312581808 512-byte hardware sectors (160042 MB) |
... |
root@tp61p:~# |
| {code} |
| {code}In this example the slices on the Solaris partition can be accessed by the Linux device names |
| {noformat} |
| {noformat}Slice Linux device name |
-------------------------------------------- |
... |
s7 sda14 |
| {noformat} |
| {noformat}There's no Linux device for the slice 5 here because this slice is not used in Solaris (the size of the slice is 0) |
| To mount the slice use:\\ \\ \\ |
| {code} \\ |
| \\ \\ |
| {code}root@tp61p:~# mount -t ufs -o ro /dev/sda8 /mnt |
| root@tp61p:~# df -k /mnt |
... |
| cdrom etc media mnt1 opt sol10hvm.save var data export milax mnt2 platform system xen |
| {code}\\ \\ |
| \\ |
If you need write access to the Solaris slices (and your Linux distribution does not support write access for UFS) or if you're using ZFS under Solaris you can start Qemu in Linux to access the data on the Solaris partition: |
| {code} |
| {code}qemu -net user -net nic -usb -usbdevice tablet -L "/usr/local/share/qemu" -boot d \ |
-m 512 -net nic,model=rtl8139 -redir tcp:1135::22 \ |
... |
-hda /dev/sda -cdrom ./milax03.iso -snapshot |
| {code}{*}Notes* |
| *Notes* |
/dev/sda is the disk (not the partition\!) with the Solaris partition |
| The parameter "-snapshot" means "write to temporary files instead of disk image files". That means that Qemu does NOT write to the harddisk. If you want to write your changes to the harddisk to can switch to the Qemu CLI with the key combination ctrl-alt-2 and issue the Qemu command "commit ide0-hd0" any time you like (see the Qemu documentation for details). To switch back to the Virtual Machine use the key combination ctrl-alt-1. You should NEVER use Qemu with access to real harddisks WITHOUT the parameter \-snapshot\!\\ |
