2.8 Rescue RAID Set
In rare cases, It may be possible to recover a failed RAIDset by using this feature. Please make
sure that any failed disk drives have been replaced prior to attempting this procedure. When
this choice is selected, a command prompt will appear. The two command choices available
are ‘RESCUE’ and ‘SIGNAT’. It is strongly recommended you contact MicroNet support prior
to using this function.
2.8.1 If the replaced disk was a member of the RAIDset and is simply out of synchronization,
you may attempt signature recovery by typing ‘SIGNAT’ in the command box, and checking
the “Confirm the operation” checkbox. Click
to commit or to revert all options to
default. A Confirmation screen appears prior to the operation conclusion.
2.8.2 If the replaced disk is new, you may attempt to force RAID rebuild by typing ‘RESCUE’ in the
command box, and checking the “Confirm the operation” checkbox. Click
to commit or
to revert all options to default. A Confirmation screen appears prior to the operation conclusion.
3. Volume Set Function
A volume set is seen by the host system as a single logical device, and is
organized in a RAID level with one or more physical disks. RAID level refers to
the level of data performance and protection of a Volume Set. The RAIDBank4
supports up to 4 simultaneous volume sets in varying RAID level configurations.
Creating volume sets require that a RAIDset is already defined- to create a
RAIDset please see Section 2.1 “Create RAIDset” of this chapter. A Volume Set
capacity can consume all or a portion of the disk capacity available in a RAID
Set, and multiple Volume Sets can exist on a group of disks in a RAID Set. All
Volume Sets created in a specified RAID Set will reside on all the physical disks
in the RAID Set, and the data spread evenly across all the disks in the RAID Set.
To access volume set functions, click on the “Volume Set Functions” Option the
main menu (illustrated right) and click to select desired menu option.

CONSIDERATIONS FOR RAID VOLUME CREATION
Your RAIDBank4 is capable of creating large logical volumes (LUNS) in excess of 2 Terabytes.
Large LUNS (>2TB) must be supported by the host bus adapter and the host Operating System to
be usable. Windows 2003, Vista, Windows 2008, Mac OS X 10.4.8, and Linux distributions with
appropriate kernels all support large LUNS. Windows XP and prior cannot address large LUNS natively
over USB, and must use eSATA host bus adapters that have RAID support to be usable. MicroNet offers such
host bus adapters- consult your MicroNet authorized reseller for more information.
