Adding Disk

[eykyn17]

Hi,

I have a HPC3600 Worstation running on HPUX11.11 then it has only 1 disk installed at slot 6.

Right now I added another disk and placed it to the slot5 then the systme recognized the disk, but this disk has a data on it. My question is:
1.How would I destroy the data I mean just like format the drive to make it usable?
what command should i use?
2.How to add this to a volume group

Hi,
use SAM, it will do all the work for you.
When you add the disk to a volume group SAM will recognise that the disk has been used before and ask if you want to use this disk.
If you say yes, SAM will issue the mkfs in the background, which will ready the disk for re-use.

Hi,

You can use "pvcreate" command to re-create LVM structure on the disk

use command vgexntend to extend this disk to an existing vg

use vgcreate command to make this disk part of a new vg

lets us know if you need more help

Hi,

First you can destroy the data using mediainit command and create a PV on that disk.You can use the following procedure to add the disk in a VG

mediainit /dev/rdsk/cXtYdZ

pvcreate -f /dev/rdsk/cXtXdX

vgextend /dev/vgXX /dev/dsk/cXtXdX

After the system has recognised the disk you need to do
1. pvcreate /dev/rdsk/c?t?d? (disk device file which you can get from ioscan -fnCdisk command
If you want to add this disk to existing volume group as vg00
2.vgextend /dev/dsk/c?t?d? /dev/vg00
of if you want to create a new volume group say vg01
mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000 (check for a free minor number)
vgcreate /dev/vg01 /dev/dsk/c?t?d?
