sounds good, going step by step!

root@host:/dev/vg01 # vgcreate vg01 /dev/dsk/c4t4d0
Warning: Max_PE_per_PV for the volume group (65535) too small for this PV (71525).
Using only 65535 PEs from this physical volume.
Increased the number of physical extents per physical volume to 65535.
vgcreate: Volume group "/dev/vg01" could not be created:
VGRA for the disk is too big for the specified parameters. Increase the
extent size or decrease max_PVs/max_LVs and try again.

How do I fix that?

Thanks, mknod group c 64 0X030000 worked like charm, a space was needed between c and 64.

Now I get the following message when i run vgcreate

Warning: Max_PE_per_PV for the volume group (65535) too small for this PV (71525).
Using only 65535 PEs from this physical volume.
Increased the number of physical extents per physical volume to 65535.
vgcreate: Volume group "/dev/vg01" could not be created:

extent size or decrease max_PVs/max_LVs and try again.

Help me, im about to get tehre!

[unix adm]

vgcreate -l 255 -p 255 -e 5000 -s 64 /dev/vgtest /dev/dsk/c4t4d0


Its just that max PE per PV is limited to the 65535 value and with this big disk
you can just try increasing the PV size.


Good luck!

srry I mean PE size instead of PV size, in the above command i have give PE size as 64 MB instead of default 4 mb.

Try the above command and it should work.


Thanks and Regards

Worked like charm:

root@host:/dev/vg01 # vgcreate -l 255 -p 255 -e 5000 -s 64 /dev/vg01 /dev/dsk/c4t4d0
Volume group "/dev/vg01" has been successfully created.
Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf

root@host:/dev/vg01 # lvcreate -L 10240M /dev/vg01 -n orau8

Usage: lvcreate

I get that error now

[Mel Burslan]

you need to specify the volume group as the last entry on the line. Your command needs to be like this :

lvcreate -L 10240M -n orau8 /dev/vg01

Hi

Use

lvcreate -L 10240 -n orau8 /dev/vg01

than

Mel:

amazing

root@host:/dev/vg01 # lvcreate -L 10240M -n orau8 /dev/vg01
Logical volume "/dev/vg01/orau8" has been successfully created with
character device "/dev/vg01/rorau8".
Logical volume "/dev/vg01/orau8" has been successfully extended.
Volume Group configuration for /dev/vg01 has been saved in /etc/lvmconf/vg01.conf

now in order to create a vxfs should I run

newfs -f vxfs -o largefiles /dev/vg01/orau8 ?
