Chapter 4 Installing the Level 2R 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. In addition, the fifth disk in the
primary RAID chassis is bound as a Hot Spare. Optionally, you can also use some
of your other disks (in groups of five) as Hot Spares Refer to
“Binding Hot Spare
drives” on page 369 for more information.
View disk properties and identify the four disks you will use for the RAID 1 LUNs,
the one Hot Spare disk, any other disks that you intend to use for 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.
