Configuring RAID
Redundant systems store metadata files and journal files on the primary RAID
chassis. The first six disk slots in the chassis are dedicated for metadata/journal
files. In the first five slots are five metadata/journal disks. The sixth slot is filled
with a blank. Two disks are bound as a RAID 1 RANK for metadata storage and
two disks are bound as a RAID 1 RANK for journal storage. The fifth disk is bound
as a Hot Spare for the other four metadata/journal disks. The remaining six disks
in the primary RAID chassis and all disks in Expansion chassis are for media
storage. Media storage disks are bound as RAID 5 or RAID 6 in RANKs consisting
of six disks each.
View disk properties and identify the four disks you will use for the metadata/
journal RAID 1 RANKs, the one metadata/journal 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. Make sure you select disks appropriately as you bind
disks in the remainder of this procedure.
2. For systems that use RAID 1 RANKs, 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 in the context
menu. (If the RAID chassis has two controllers, both controllers are represented
by the single “Controller” node)
The Bind dialog box opens showing all unbound disks for the controller listed
in the Available Disk list.
