3. Click OK. Changing the data protection level 1. In the Data Protection Level drop-down list, select the level of Network RAID you want. Changing a volume to either Network RAID-5 or Network RAID-6 requires that volume to have a snapshot schedule. If the volume does not already have a snapshot schedule related to it, one will be created automatically. This default schedule is named VolumeName_Schedule, recurs once daily, and retains 1 copy. You can edit this schedule as desired, as described in "Editing scheduled snapshots" on page 225. 2. Click OK when you are finished. Changing the size 1. In the Size field, change the number and change the units if necessary. 2. Click OK when you are finished. CAUTION: Decreasing the volume size is not recommended. If you shrink the volume in the CMC before shrinking it from the server file system, your data will be corrupted or lost. Deleting a volume Delete a volume to remove that volume's data from the storage system and make that space available. Deleting a volume also deletes all the snapshots underneath that volume, except for clone points and shared snapshots. For more information, see "Clone point" on page 242 and "Shared snapshot " on page 244. CAUTION: Deleting a volume permanently removes that volume's data from the storage system. Restrictions on deleting volumes You cannot delete a volume when the volume has a schedule that creates remote copies. You must delete the remote copy schedule first. CAUTION: Typically, you do not want to delete individual volumes that are part of a volume set. For example, you may set up Exchange to use two volumes to support a StorageGroup: one for mailbox data and one for logs. Those two volumes make a volume set. Typically, you want keep or delete all volumes in a volume set. P4000 SAN Solution user guide 211
