7.3.10.10 Adding Units
Enter option 7 (HSJ and HSD30 array controllers) or option 6 (HSZ array
controllers) from the main menu to work with units. From the unit menu
(see Figure 7–18), enter option 1 to add a unit. CFMENU will ask you which
initialized containers you wish to create units from.
CFMENU also will ask you to assign a unit number. (The program automatically
assigns a ‘‘D’’ or ‘‘T’’ to the unit number when listing the unit, as shown in
Figure 7–18.) In addition, CFMENU will ask you to decide on other unit
qualifiers. See the description of the ADD unit or SET unit commands in
Appendix B if you need help understanding the qualifiers.
In Figure 7–18, a unit was created from stripeset S1.

CFMENU updates the following fields after adding a unit:
• Reduc—Reduced. This field indicates whether or not a RAIDset is running
reduced (missing one member).
• Unit—The unit number you assign appears here, preceded by the letter ‘‘D’’
or ‘‘T.’’
• WP—Write protect. This value indicates whether or not the unit is write
protected.
• WB—Write-back. This value indicates whether or not the unit is set for
write-back caching.
