Thanks hicksd8.
I didn't have the idea that it needs all those steps to be done.

I am surely not expert, but have some idea of the stuff. If possible, could you give me some steps for creating this virtual disk with extra space from the existing one.

For starter, when I run "format" command on the simulator, on just the original one, I get errors:
Code:
bash-3.00# format
Searching for disks...WARNING: hsimd_ioctl: cmd 410 not implemented


Error: Device c0t0d0: controller name (SUNW,sun4v-virtual)
is invalid.  Device will not be displayed.
done
No disks found!

Also, if i just use the following command to clone the original disk, it works just fine:
Code:
dd if=/export/home/ramdisk/disk/s10hw2 of=/export/home/ramdisk/0

i guess I am going to need help on creating this bigger disk ...Smilie

Thanks

NAME
pseudo - configuration files for pseudo device drivers DESCRIPTION
Pseudo devices are devices that are implemented entirely in software. Drivers for pseudo devices must provide driver configuration files to inform the system of each pseudo device that should be created. Configuration files for pseudo device drivers must identify the parent driver explicitly as pseudo, and must create an integer property called instance which is unique to this entry in the configuration file. Each entry in the configuration file creates a prototype devinfo node. Each node is assigned an instance number which is determined by the value of the instance property. This property is only applicable to children of the pseudo parent, and is required since pseudo devices have no hardware address from which to determine the instance number. See driver.conf(4) for further details of configuration file syntax. EXAMPLES
Example 1: A sample configuration file. Here is a configuration file called ramdisk.conf for a pseudo device driver that implements a RAM disk. This file creates two nodes called "ramdisk". The first entry creates ramdisk node instance 0, and the second creates ramdisk node, instance 1, with the additional disk-size property set to 512. # # Copyright (c) 1993, by Sun Microsystems, Inc. # #ident "@(#)ramdisk.conf 1.3 93/06/04 SMI" name="ramdisk" parent="pseudo" instance=0; name="ramdisk" parent="pseudo" instance=1 disk-size=512; SEE ALSO
