D.1.2 Add the STRIPEset as a Logical Unit
To make a STRIPEset available to the host computer, you must add it as a host logical
unit with a unique unit number. The unit number is a one or three digit number preceded
by “D”, such as “D0” or “D102”. The unit number is made of the controller’s target ID
and the Logical Unit (LUN) of the STRIPEset for the target. Each target ID can have up
to eight LUNs, numbered 0–7.
•
Units identified with controller target ID 0 have a single digit number which
corresponds to the LUN number. For example, D5 would be target 0, LUN 5.
•
Units identified with all other controller targets (1–7) use a 3 digit number. The first
digit corresponds to the controller target number, the second digit is always 0 and the
third digit is the LUN number. For example, D205 would be target 2, LUN 5.
Identify the STRIPEsets as host logical units by using the ADD UNIT command.
HSZ20> ADD UNIT D100 STRIPE1
This example creates LUN 0 for controller target ID 1 (specified earlier with the SET
THIS_CONTROLLER command).
D.1.3 Set Writeback Cache
The final step in creating a STRIPEset is to enable the writeback cache. A single CLI
command enables that feature for the entire STRIPEset:
HSZ20> SET D100 WRITEBACK_CACHE
Where D100 represents the host logical unit of the STRIPEset created above.
D.2 Create a MIRRORset (Configuration Example 1)
If your site requires MIRRORsets for storage, you must assign disks to each
MIRRORset. MIRRORsets must have at least two members, and can have as many as
six. This example creates a two-member MIRRORset using the ADD MIRRORSET
command.
HSZ20> ADD MIRRORSET MIRROR1 DISK120 DISK210
In this example, “MIRROR1” is the name of the MIRRORset, and it is followed by a list
of the disks to be included in the MIRRORset. The names of the MIRRORsets are user-
defined. Performance of your MIRRORsets will be optimized if each MIRRORset
includes disks from different buses as shown in Figure 2–1 in Chapter 2. The example
above contains disks from two different buses.
D.2.1 Initialize the MIRRORset
You must initialize a MIRRORset before you can put it into service.
