208 K2 Storage System Instruction Manual July 3, 2007
Chapter 5 Installing the Level 3R Storage System
Redundant systems store metadata files and journal files on the primary RAID
chassis, which requires a RAID 1 LUN (two disks) for metadata storage and a
RAID 1 LUN (two disks) for journal storage. The RAID 1 LUNs must be bound
from the first four disks (counting from left to right as you face the front of the
RAID chassis) in the primary RAID chassis. These disks must be 15K rpm drives.
In addition, the fifth disk in the primary RAID chassis (also a 15K drive) is bound
as a Hot Spare. This fifth 15K disk then provides Hot Spare functionality for the
other four 15K disks (the RAID 1 LUNs) only. Optionally, you can also use some
of your other 10K disks (in groups of five) as Hot Spares for your media storage
LUNs. Refer to
“Binding Hot Spare drives” on page 381 for more information.
View disk properties and identify the four disks you will use for the RAID 1 LUNs,
the one 15K Hot Spare disk, any other disks that you intend to use for media LUN
Hot Spares, and the remainder of the disks that are available for media storage
LUNs. Make sure you select disks appropriately as you bind LUNs in the
remainder of this procedure.
2. For systems that use RAID 1 LUNs, you must now create the separate RAID 1
storage for metadata files and journal files. To bind unbound disks for metadata and
journal storage, do the following:
a. Right-click the
Unbound
node for the controller, then select
Bind LUNs
in the
context menu. (If the RAID chassis has two controllers, both controllers are
represented by the single “Controller” node)
The Bind LUN dialog box opens showing all unbound disks for the controller
listed in the Available Disk list.
