Hi all

We like to create a vg our storeage is emc. EMC gave us a LUN about 500 GB. after pv and mknod when we try to create VG with the following command
vgcreate -e 20000 –s 32 /dev/vg_restore /dev/dsk/c7t1d2
I have got the following error
vgcreate: Cannot open the control file "/dev/vg_restore/group":
No such device

Hi,

What is the value of maxvgs in your kernel

=> grep maxvgs /stand/system
The default is 10

you are using 10 (hex), in this case the kernel parameter must be at least 16

Hi Robin,

This is beacuse of the"maxvgs" kernel parameter limitation.Try to increase this value and try again it will work.

Regards!
