4–6 Configuring Storagesets
Configuring a RAIDset
See “Creating a Storageset and Device Profile,” page 3–5 for information about
creating a profile and understanding the switches you can set for this kind of storage
unit.
To configure a RAIDset:
1. Create the RAIDset by adding its name to the controller’s list of storagesets and
specifying the disk drives it contains. Optionally, you can append RAIDset
switch values. If you do not specify switch values, default values are applied.
Use the following syntax to create a RAIDset:
ADD RAIDSET RAIDset-name DISKnnnn DISKnnnn DISKnnnn switch
See “ADD RAIDSET,” page 5–19 for switches and values.
2. Initialize the RAIDset. Optional: If you want to set the Initialize switches, you
must do so in this step. Use the following syntax:
INITIALIZE RAIDset-name switch
See “INITIALIZE,” page 5–62, for valid switches and values.
NOTE: It is recommended that you allow initial reconstruct to complete before
allowing I/O to the RAIDset. Not doing so may generate forced errors at the host
level. To determine whether initial reconstruct has completed, enter SHOW
RAIDSET FULL.
3. Present the RAIDset to the host by giving it a unit number the host can recognize.
Optionally, you can append Unit switch values. If you do not specify switch
values, default values are applied.
Use the following syntax to present the RAIDset to the host:
ADD UNIT unit-number RAIDset-name switch
See “ADD UNIT,” page 5–27, for valid switches and values.
