I haven't tried it, but the point is that it is a raw disk - i.e. FS unknown... so things such as 'blocksize' does not exist or unknown...
I just need to open the device... in a C program... like in Linux the HDD devices are /dev/sda, /dev/hda, etc...

I have been tasked with archiving Oracle tables. The data is on raw devices, and possibly will span multiple logical volumes.
Has anyone ever had to do this? How did you accomplish it?
Any references to accomplish this would be greatly appreciated.

Hi,
I'm in process of creating oracle RAC using Solaris 10 in VirtualBox. I want to know how can I change the ownership of device e.g /dev/rdsk/c0t3d0s0 and keep it persistent during rebbots.
When I enter
chown grid:install /dev/rdsk/c0t3d0s0
ls -l still shows root:root.
Thanks

HD(4) Linux Programmer's Manual HD(4)
NAME
hd - MFM/IDE hard disk devices
DESCRIPTION
The hd* devices are block devices to access MFM/IDE hard disk drives in raw mode. The master drive on the primary IDE controller (major
device number 3) is hda; the slave drive is hdb. The master drive of the second controller (major device number 22) is hdc and the slave
hdd.
General IDE block device names have the form hdX, or hdXP, where X is a letter denoting the physical drive, and P is a number denoting the
partition on that physical drive. The first form, hdX, is used to address the whole drive. Partition numbers are assigned in the order
the partitions are discovered, and only nonempty, nonextended partitions get a number. However, partition numbers 1-4 are given to the
four partitions described in the MBR (the "primary" partitions), regardless of whether they are unused or extended. Thus, the first logi-
cal partition will be hdX5. Both DOS-type partitioning and BSD-disklabel partitioning are supported. You can have at most 63 partitions
on an IDE disk.
For example, /dev/hda refers to all of the first IDE drive in the system; and /dev/hdb3 refers to the third DOS "primary" partition on the
second one.
They are typically created by:
mknod -m 660 /dev/hda b 3 0
mknod -m 660 /dev/hda1 b 3 1
mknod -m 660 /dev/hda2 b 3 2
...
mknod -m 660 /dev/hda8 b 3 8
mknod -m 660 /dev/hdb b 3 64
mknod -m 660 /dev/hdb1 b 3 65
mknod -m 660 /dev/hdb2 b 3 66
...
mknod -m 660 /dev/hdb8 b 3 72
chown root:disk /dev/hd*
