How to install new harddisk in system

[Henry Chua]

If I have a ignite recovery disk, and my system crashed.

1. Can I just put in the raw unformated harddisk and setup the system using the disk?

2. By doing so, do I get back the all the vg and lvs?

3. If the system has a bad physical block, will I be able to create a recovery disk, then fix the error upon installation?

4. Do I need to configure the BIOS or anything if I am installing a harddisk of a different model (different size etc.). If so, how do I do that?

thank you all for your help!!

Hi Henry,

Did you mean you have a free disk and you want to recover the system using the ignite tape onto it?.

If so, yes. If you didn't make any changes to your Volume groups then you will be able to get everything restored including importing of the volume groups. All you have to do is to put the disk in any slot, boot the system through make_tape_recovery tape, interact with the installation and select the new disk as the boot disk.

Thanks for the info Sri.

But I was thinking of installing a bigger harddrive this time... do I need to configure anything to make it work?

Thank you all for your kind advise!!!

Hi Henry,

if the ignite recovery disk is made with the option -i than you get a menu during installation where you can configure a bigger disk. Otherwise I don't know if it will work.

To 2: You get in minimum all datas from your boot disk - depends to the options you set in make_recovery.

To 3: If the system doesn't boot after fsck, you only can try to mount the old disk to the system after booting with new disk. But then I think you don't need to create a recovery disk - just copy the files you need.
If the system doesn't mount because it asks for fsck, then try to mount with option -f (for force).

Henry,

In fact, make_tape_recovery/ignite is the safe way to increase the size of the boot disks. So, the answer is happily yes.

You do not need to anything. Simply boot the system from make_tape_recovery tape, interact with install window and select the new disk.

Hi! Leandro,

From what I understand you had the application disk on a separate volume group (let's say vg01).

This should work just fine as I do this day in and day out.

ioscan -fnkCdisk
Note the device name for the application disk (let's say /dev/dsk/c1t2d0)

mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgimport /dev/vg01 /dev/dsk/c1t2d0
vgchange -a y vg01
vgcfgbackup vg01
vgscan -v

Make sure that you /etc/fstab is intact, if not restore /etc/fstab from the latest full backup. Then run

mount-a

If you cannot find restorable /etc/fstab then you would have to mount each filesystem manually.

Hope this helps!!
