try this one ... should work on any solaris ... (assumes source disk disk0 is c0t0d0 and disk1 is c0t1d0) ... you might also want to add code to modify the /etc/vfstab automatically so you can quickly boot-up with the 2nd disk --- i'll let you handle that part ... test on useless system first though just to be safe ...

Disk cloning
I had an external SCSI master disk that I used to clone to an identical external SCSI disk because the other SCSI disk would become corrupted. My original Master became corrupted so I used one of the other to good disk to copy back to the master. Unfortunately the new master needs... (1 Reply)
Hi.
We tried cloning a SCO Unix hard disk using Norton Ghost.
However, the new cloned hard disk encounter booting problem.

Continuing saga of working on making a retail store more robust by creating a backup clone of the main server, a 1995 era :eek: PC running SCO OpenServer 5.0.0b and a discontinued Point of Sales (POS) software system.

I wasn't sure where to put this thread but since i use ubuntu for data recovery, I figured this is the best place. So, a friend passed me a 250G Western Digital hard disk the other day and said that his client needs to get her pictures off it. the problem: windows says it wants to reformat the... (13 Replies)
hello folks,
I have a 300GB ROOTVG volume groups with one filesystem /backup having 200GB allocated space
Now, I cannot alt disk clone or mirrorvg this hdisk with another smaller disk. The disk size has to be 300GB; I tried alt disk clone and mirrorvg , it doesn't work. you cannot copy LVs as... (9 Replies)
Guys can anyone tell how can we do faster disk cloning
Below i found in google
1. dd if=/dev/sda of=/dev/sdb bs=4096 conv=noerror,sync
So adding "conv=noerror,sync " makes it faster looks against not adding it
2. Enable write cache activated (hdparm -W1 /dev/sda) then run dd ..

Hi,
I am trying to clone the hard disk image of Solaris OS on one disk to another disk. After some googling I found that there is a command "dd" to achieve this.
However there is a condition to use the dd command, that the disk geometry of both the disks (source and target disks) should... (5 Replies)

disklabel
disklabel(4) Kernel Interfaces Manual disklabel(4)NAME
disklabel - Disk pack label
SYNOPSIS
#include <sys/disklabel.h>
DESCRIPTION
Each disk or disk pack on a system may contain a disk label which provides detailed information about the geometry of the disk and the par-
titions into which the disk is divided. It should be initialized when the disk is formatted, and may be changed later with the disklabel
program. This information is used by the system disk driver and by the bootstrap program to determine how to program the drive and where
to find the file systems on the disk partitions. Additional information is used by the file system in order to use the disk most effi-
ciently and to locate important file system information. The description of each partition contains an identifier for the partition type
(standard file system, swap area, etc.). The file system updates the in-core copy of the label if it contains incomplete information about
the file system.
The label is located in sector number LABELSECTOR of the drive, usually sector 0 (zero) where it may be found without any information about
the disk geometry. It is at an offset LABELOFFSET from the beginning of the sector, to allow room for the initial bootstrap. The disk
sector containing the label is normally made read-only so that it is not accidentally overwritten by pack-to-pack copies or swap opera-
tions; the DIOCWLABEL ioctl, which is done as needed by the disklabel program, allows modification of the label sector.
A copy of the in-core label for a disk can be obtained with the DIOCGDINFO ioctl; this works with a file descriptor for a block or charac-
ter (raw) device for any partition of the disk. The in-core copy of the label is set by the DIOCSDINFO ioctl. The offset of a partition
cannot generally be changed, nor made smaller while it is open. One exception is that any change is allowed if no label was found on the
disk, and the driver was able to construct only a skeletal label without partition information. Finally, the DIOCWDINFO ioctl operation
sets the in-core label and then updates the on-disk label; there must be an existing label on the disk for this operation to succeed.
Thus, the initial label for a disk or disk pack must be installed by writing to the raw disk. All of these operations are normally done
using the disklabel program.
