This is a DS2100? Just insert the disk and run ioscan +

# insf -H 0/2/1/0.4.0

Hi,

as suggested by Torsten, if this is DS2100 disk enclosure, insert the disk (you can do that online) , ioscan , insf -eCdisk,then normally do pvcreate, vgcreate/vgextend to that path , lvcreate/lvextend etc.
regards
sujit

Hi,
As per the output of ioscan -fnC disk it seems you already add those disk into the server.

disk 2 0/1/1/0.1.0 sdisk CLAIMED DEVICE HP 146 GMAP3147NC
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0
disk 3 0/1/1/1.2.0 sdisk CLAIMED DEVICE HP 146 GMAP3147NC
/dev/dsk/c3t2d0 /dev/rdsk/c3t2d0

now you can create vg or extend vg into other existing vg with vgcreate or vgextend command.

Shalom,

It looks like you already have added the disk.

Unless you are tyring to replace the 36.4 GB disk.

If so:

insf -C disk

Try the ioscan again.

After the ioscan:
pvcreate /dev/rdsk/c2t0d0s2
pvcreate /dev/rdsk/c2t0d0s3

thanks all for your quick respose the vg00 is the whole 36GB drive when i try to add the 146GB drive to that vg00 it tells me that the capacity is only 36GB all the other disk space will go to waste .How can i chnage the capacity of the vg00 so i can add the 146GB drive to that .

Thanks all for your help ...

When originally created, your vg00 was allowed to use the default values for max_pe and pe_size. The default accommodates the original 36GB drive but all subsequent additional drives are limited to that same size. In 11.31 and, I think, 11.23 with a patch, there is provided a vgmodify command that can be used to modify this restriction. Without vgmodify, you will need to create an Ignite backup then restore that backup, modifying your root volume layout to include the new disk.
