[dlt_2]

T added 3 new discs on HP disk System 2300. I would like to know procedure to add this 3 discs on existant volume group ?

ioscan -fnCdisk :

disk 9 0/3/0/1.0.0.1 sdisk CLAIMED DEVICE I2O RAID5
/dev/dsk/c6t0d1 /dev/rdsk/c6t0d1

use pvcreate to mark them to be used in a volume group, then use vgextend to add them into the volume group

man pvcreate
man vgextend

Shalom,

ioscan to see if you can see them.
insf -C disk
pvcreate -f # each new disk

vgextend vg## for each disk.

Then work with the logical volume management.

Hi,
1.first create device files for that device using
insf -c disk
2.then to create physical volume
pvcreate -f /dev/rdsk/c1t2d3

-f --> if disk is previously part of other vg.
3.check it with
vgdisplay -v vgname
4.then
vgextend vgname /dev/dsk/c1t2d3

Hi,

look at this:

disk 9 0/3/0/1.0.0.1 sdisk CLAIMED DEVICE I2O RAID5
/dev/dsk/c6t0d1 /dev/rdsk/c6t0d1


This is NOT a plain disk!



Your disk chassis is connected to a RAID4si controller. What you can see in the ioscan is a RAID LUN (#1).

You need to create a new LUN on your new disks! Use SAM (the included RAID Manager tool) "irm" to make this!

[Torsten.]

Once the new LUN is created, you will get a new device file by running "ioscan" followed by "insf -eCdisk", let's say

/dev/dsk/c6t0d2

for LUN2.
Now you should proceed with
pvcreate
and
vgextend.

Hi;

Please follow the following instruction:

#diskinfo /dev/rdsk/cxtxdx

if all the disks are present, then..

#insf -C disk (optional)

#strins /etc/lvmtab (check if the disk is not used in any VG)
#vgdisplay -v |grep -i disks (cross verify)
if the disks are not present, then..

#pvcreate -f /dev/rdsk/cxtxdx
#vgextend vg03 /dev/dsk/cxtxdx (all the disks)

(please u -g PVG01 with vgextend command if u need to support distribuation policy)

#vgextend vg03 /dev/dsk/cxtxdx (with alternet disk info)
#vgdisplay -v vg03 (check if all the disk are present in the VG)

Please change the PV timeout to 3 min

#pvchange -t 180 /dev/dsk/cxtxdx.

Hope above information will help you to resolve ur issue.

All the best..

Cheers;
Indrajit Roy

It's ok thanks for all !

1 - I used irm command to create a new logical volume

disk 10 0/3/0/1.0.0.2 sdisk CLAIMED DEVICE I2O RAID5
/dev/dsk/c6t0d2 /dev/rdsk/c6t0d2

2 - i used "insf -eCdisk"

/dev/rdsk/c6t0d2
/dev/dsk/c6t0d2

3 - i used "pvcreate -f /dev/rdsk/c6t0d2"

4 - i used "vgextend vg03 /dev/dsk/c6t0d2"
