This procedure enables you to rename a logical volume without losing any data on the logical volume. The file system associated with the logical volume must be unmounted and then renamed.
It is important to have an understanding of the following:
In this example, the logical volume is changed from lv00 to hd33.
Note: You cannot use the umount command on a device in use. A device is in use if any file is open for any reason or if a user's current directory is on that device.
chlv -n hd33 lv00
Note: If you rename a JFS log, you are prompted to run chfs on all file systems that use the renamed log device.
