Software :: Adding Drive - Extending VG And LV - Partition New Drive?

I need to expand one logical volume which is now in 99% utilization. The volume group only have 5GB and they need 25GB more so that I can add 30GB. The disks will be coming from SAN Storage. If the SAN Admin can successfully add the disks to the server and I can see it, should I still partition it and change the type to Linux LVM?

I have tried just doing a pvcreate without partitioning and do a vgextend and it works without actually partitioning the disks. But when I do "fdisk -l", it actually shows that the disk don't have partition.

Whether I need to partition the drive to 8e (Linux LVM) before doing? Which one is better? Below are my steps and please let me know if this the correct one.

Here's my steps:

1.) dmesg | grep sd (to check the newly added disks)
2.) fdisk /dev/sdx (create primary partition and assign Linux LVM to type)
3.) pvcreate /dev/sdx
4.) vgextend VolumeName /dev/sdx
5.) lvextend -L+30G Volume01 /dev/Volume01/lv01
6.) umount /dev/Volume01/lv01
7.) resize2fs /dev/Volume01/lv01
8.) mount /dev/Volume01/lv01 /lv01
9.) df -h (check if resized successfully)
