Extending VA7100
Please see attached file where you can see vgdisplay and ioscan results.
We have two VG vg00 and vgBAL, 3 LUNs (c4t0d1, c4t0d2, c4t0d3) We want to know what is c4t0d0 ?
We want to add 10 new 36 GB disks to our VA. After we have physically added the 10 disk at the same time
We must wait the OS to format evry disk (how many time it will take ?)
Then create new 80 GB LUN with command :
#armcfg -L 4 -a 80000 -g 1 myArray
there will be new /dev/dsk/c4t0d4 /dev/rdsk/c4t0d4 created by the OS ?
Then we must initialize this disk as an LVM disk by using the pvcreate command.
#pvcreate -f /dev/rdsk/c4t0d4
#diskinfo /dev/rdsk/c4t0d4
We can add this PV disk to volume group vgBAL
#vgextend vgBAL /dev/dsk/c4t0d4
Extend logical volume to 80000 MB
#/usr/sbin/lvextend -L 80000 /dev/vgBAL/rlvolBAL2
And we can repeat the process with evry new LUN to create.
Is this process is ok to create new LUN and extend VG and LV ?

Re: Extending VA7100
Don't use it for data!
# vgdisplay -v /dev/vgBAL
...
Max PE per PV 2047
...
PE Size (Mbytes) 4
This means the maximum PV size is limited to ~8GB!
You cannot add a 80GB LUN to this VG!
Hope this helps!
Regards
Torsten.

Re: Extending VA7100
Thanks for your response.
We want to add about 140 GB to our vgBAL logical volums but it seem that maximum PV number is 16 where and there is 3 PV now, that mean that we can add only 13 PVs i.e. 13 x 8 GB = 104 GB to this vg.
How we can chage volume group parameters to allow us to add 140 GB or more.

Re: Extending VA7100
With 11.11 or lower you can only backup the data, remove and recreate the VG.
With 11.23 or higher you can adjust the settings using vgmodify.
Hope this helps!

Torsten.

Re: Extending VA7100
Thank you for you quick replay.
We are on B.11.11 hence we have to delete vgBAL vg and recreate it.
If we remove the vg it will affect the applications or the OS ?
To create a volume group named /dev/vgBAL that can contain a maximum of 255 logical volumes and 32 physical volums, with extent size set to 8 MB :
#mkdir /dev/vgBAL
#mknod /dev/vgBAL/group c 64 0xNN0000
#vgcreate ├в p 32 -s 8 /dev/vgBAL
But I have two questions :
1- How to find NN
2- How to define the Max PE per PV parameter

Re: Extending VA7100
You can also use vgexport to get rid of the vg and start over with pvcreate ...
Find out the current NN and re-use it after you removed the vG.
vgcreate -e max_pe ...

Hope this helps!
