You might need to temporarily restrict user access to a storage pool or volume. Instead of bringing down the server, you only need to deactivate the specific volume or pool. You can deactivate both storage pools and volumes; however, you can only do maintenance (rebuild and verify) on storage pools. This means that users will be unable to access any of the volumes in the pool while you run REBUILD and VERIFY. When you use REBUILD and VERIFY a log file is generated to the root of the DOS drive. For instructions on running REBUILD and VERIFY, see Rebuilding NSS Storage Pools and Volumes.
From ConsoleOne, open the tree you want.
Right-click on the server object and select Properties.
Click Media > NSS Pools or Logical Volumes.
Select the storage pool or volume you want to activate or deactivate.
Click Activate or Deactivate.
Click Activate when you are ready to restore access to the volume or pool.
