Configuring and Managing Storage Units
The AppResponse 11 6170 base unit (SCAN-06170) and the 8170 base unit (SCAN-08170) have no internal storage. You can connect storage units of the same model, either SCAN-SU-48TB or SCAN-SU-72TB to a base unit.
• Up to eight external storage units can be connected to a 6170 base unit for storage.
• Up to sixteen external storage units can be connected to an 8170 base unit for storage.
When a new base unit is connected to power it detects the storage units. As of Version 11.9.0, AppResponse 11 does not initialize Storage Units automatically; you must initialize them manually after installation. For new AppResponse 11 installations, this is handled by the setup wizard, which prompts you to initialize the Storage Units and specify their RAID mode and encryption. After installation of a new AppResponse 11 system, the CLI command storage reinitialize can be used to initialize and configure multiple Storage Units in the same manner as the wizard. Note that, when a new Storage Unit is attached at a later time, it will be detected automatically. This applies to SCAN-SU-48T, SCAN-SU-72TB, SCAN-SU-4, SCAN-SU-10, and EXP-300 units. Storage is initialized as RAID 0 by default
• Initialization is done at the storage unit level, that is, an uninitialized storage unit is initialized whenever the base unit boots.
• Initialization fails
o if an invalid storage unit is detected
o if a disk fails
o If an incompatible disk is found
• The initialization process formats storage as RAID 0 storage by default. After initialization, storage can be reinitialized as RAID 1, RAID 5, or RAID 6 for storage redundancy, using the AppResponse 11 CLI.
• If a storage unit fails or is removed, storage may continue to function but with a limited capacity. If all storage units fail or are removed, storage will not function.
• Reinitializing a storage unit destroys all data on that single storage unit. All other storage units are unaffected.
