Volume removal

You can remove a volume from a storage pool. During this process, any files that are stored in the volume are automatically redistributed among the remaining volumes in the same storage pool. When you remove a volume, data is moved and committed one logical partition at a time. If a failure occurs while moving the contents of a volume, you can reissue the command, and the move process continues where it stopped earlier.

If I/O errors occur for some files or if the redistribution of the files to other volumes fails, you can specify a force option that causes the volume to be removed anyway. If there is a bad file on the volume, specifying this option causes the system to delete the entire file, even if parts of the file reside on other volumes.

If the bad file is part of a FlashCopy® image, SAN File System removes it from the FlashCopy image. This removal might render the FlashCopy image non-revertible. You can still backup and restore the remaining files on the FlashCopy image.

Remember: There is no automatic recovery process when you specify the force option. All files are removed immediately without being copied. Before removing a volume with the force option, use the reportvolfiles command to display a list of files on the volume. The files for which failures occur are also listed in the cluster message log, and you can restore those files manually.

When you remove a volume from a storage pool, its label is removed, and the volume becomes a logical unit number (LUN) again.
