pvcreate /dev/vg0 .........successfully created
mkdir /dev/vg00
mknod /dev/vg0/group c 64 0x030000
vgcreate /dev/vg0 /dev/dsk/c0t0d0

Iam unable to vgcreate successfully on hp-ux 11i v3.

Any one help will be appreciated..........

Can you post the output from
# diskinfo /dev/dsk/c0d0t0

Usually this is DVD rom.

Check also disk drives:
#ioscan -fnC dick

Re: rx2660 = Hp-ux 11i v3 Unable to create volume group

With 11.23 on this server model the device c0t0d0 is most likely the DVD, but on 11.31 this is not possible, because the drive is USB and the device file is totally different.

What error message you get from "vgcreate"?

Hope this helps!

Torsten.

Re: rx2660 = Hp-ux 11i v3 Unable to create volume group

Hi,

Iam unable to send you the ioscan output , But the suconfig utility clear pints the logical volume is c0t0d0.

The error is #vgcreate not done use maxextents 65352 etc.

Another question is how can i make SPARE DISK available into single group ..... for example three disk up and running i wanted to add this two SPARE disks to up & running system which makes my server total of 5disks.

Re: rx2660 = Hp-ux 11i v3 Unable to create volume group

You probably need to increase the PE_size value in vgcreate, because the MAX_PE value is higher than allowed otherwise.

You currently have already 2 spare disks - IMHO too much, 1 would be enough.

Hope this helps!

Re: rx2660 = Hp-ux 11i v3 Unable to create volume group

Your current design is IMHO not the best.

What do you want to do with a 280GB large logical drive? Creating vg00? This is overkill.
You have 2 spare disks, but none is assigned to the existing logical drive - maybe you used a wrong commend to configure?

Hope this helps!

Torsten.

Re: rx2660 = Hp-ux 11i v3 Unable to create volume group

Hi Tor,

This vg00 280GB configured under hardware RAID 5 which consist of 3 SAS disks.

UNASSIGNED disk changed to SPARE disks with the help of below command.

#saconfig /dev/ciss0 -A 0 -s

Re: rx2660 = Hp-ux 11i v3 Unable to create volume group

280 GB for vg00 is much too large.

Hope this helps!
