How to remove the LUN in RHEL?

Hi,

How to remove the allocate SAN Lun on the Linux Server. I am using rhel 5.8. I have assigned a LUN to the existing Volume group.
For eg: I have allocated a LUN with 20GB to the existing volume group(test123). Now, how can I take back the allocated lun without any issues.

If a device is no longer required for use by LVM, you can remove the LVM label with the pvremove command. Executing the pvremove command zeroes the LVM metadata on an empty physical volume.

If the physical volume you want to remove is currently part of a volume group, you must first remove it from the volume group with the vgreduce command.

Before you use vgreduce, you may have to shrink one or more filesystems.

Before doing anything you really should read https://access.redhat.com/knowledge/...ion/index.html
