[Asif_8]

What are the steps I need to do to create vg group
Here is the "powermt display dev=all" of the other LUNS

Its no different than a local disk group. Same procedure, different location (disk path)

pvcreate
mkdir /dev/
mknod
vgcreate

Hi Asif

if you consider your first lun shows in powermt display dev=all
LUN ID - 900

you may follow the steps

1. pvcreate of first disk
2. mkdir
3. mknod
4. vgcreate using the first disk
5. vgextend the next 3 disks
6. lvcreate
7. file system create
8. mkdir mount_point
9. mount.

Have fun!!

Dear Asif,

powermt display dev=all

Creating Vg
------------------------------------
#pvcreate /dev/
u r planning to create a volume group is Vg01
# mkdir â p /dev/vg01
# mknod /dev/vg01/group c 64 0x040000
# vgcreate /dev/vg01 /dev/
#vgdisplay â v /dev/vg01
# vgextend /dev/vg01 dev/
#lvcreate â L 2000M â n vol1 /dev/vg01
# mkfs â F vxfs /dev/vg01/vol1
# mkdir â p /vol1
# mount /dev/vg01/vol1 /vol1
# vi /etc/fstab

Hi Asif,

I prefer to use the command line to create LVM stuff. However, you can also use "SAM" to achieve the same results.

Hi Asif,
Please don't forget to set the PV TIMEOUT (normally it is 90 seconds on EMC2 SAN) and the LV BAD BLOCK RELOCATION to NONE.
To set up the PV TIMEOUT you have to run, on all disks prymary path, the command
pvchange -t 90 /dev/dsk/
The command must be run after the PV is added into the VG.
To set up the BAD BLOCK RELOCATION you have to create the LV with the option -r N or , if the logical volume is already created, you can change it whith command lvchange

lvchange -r N /dev//

You can find some more detail in EMC2 Manual :"EMC Host Connectivity Guide for HP-UX".
The manual is downloadable from EMC2 powerlink site.
