LD The logical drive number
RAID The RAID level
Size The logical drive size
#Stripes The number of stripes (physical drives) in the associated
physical array
StrpSz The stripe size
Drive-State The state of the logical drive
6. To set the RAID level for the logical drive, highlight RAID and press
Enter. The available RAID levels for the current logical drive appear.
Select a RAID level and press Enter to confirm.
7. Set the spanning mode for the current logical drive. Highlight Span and
press Enter. The choices are:
•
CanSpan: Array spanning is enabled for the current logical drive. The
logical drive can occupy space in more than one array.
•
NoSpan: Array spanning is disabled for the current logical drive. The
logical drive can occupy space in only one array.
If you select CanSpan, HP NetRAID Express Tools will attempt to span up
to four arrays. Array spanning stops when:
•
It has created a logical drive of the size you specify in Step 8 below.
•
The next sequentially numbered array has a different number of drives.
(Spanned arrays must contain the same number of drives in each array.)
For example, assume Array 1 contains four disk drives. Also assume that
Arrays 2 and 3 have four disk drives, but Array 4 has three disk drives.
HP NetRAID Express Tools spans Arrays 1, 2, and 3 but not Array 4.
8. To set the logical drive size, move the cursor to Size and press Enter. By
default, the logical drive size is set to all available space in the array(s)
being associated with the current logical drive. If you set the Span
parameter to CanSpan in Step 7, the current logical drive will use all space
in the current array, and all space in the spanned arrays.
•
If you want to create more than one logical drive in an array, set a size
of less than the actual capacity.
•
If you want the logical drive to span arrays, but you want it to span
only two or three arrays, rather than the four-array maximum, set a size
of less that reflects the number of arrays you want to span.
