7.0 Modify Storage
Use the ExpressNAV Storage Manager to replace a failed drive, add new drives or redesign RAID configurations.
You may modify various aspects of storage using the Manage Menu found by clicking on the tab on the left hand side of the ExpressNAV Storage Manager. Be cautious when deleting storage or rearranging storage configurations because data could be compromised or lost.
The ExpressNAV Storage Manager takes you step by step through many procedures which allow you to modify your storage and RAID configurations. Read all notes and cautions carefully as you go to ensure the best performance and use of your storage.
When you initially set up the FastStream, replace a failed drive or add new drives to the FastStream, perform drive initialization and verification to these drives.Refer to Ensure Drive Integrity on page 11.
Many of these procedures are only available on unallocated storage which is not currently part of a RAID group, not designated as a Hot Spare (refer to FastStream process: adding or removing Hot Spares on page 34), or was offline when you initially set up RAID configurations.
Preliminary steps
Begin with these steps, then choose the process you wish to use.
