Press Esc to exit the Advanced Menu.
9. Highlight Span and press Enter to set the spanning mode for the current
logical drive. The options are:
•
CanSpan: Array spanning is enabled for the current logical drive. The
logical drive can occupy space in up to four arrays.
•
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 attempts to span up to
four arrays. Array spanning stops when:
•
It has created a logical drive of the size you specify in Step 7 above.
•
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 will span Arrays 1, 2, and 3 but not Array 4.
10. When you are finished defining the current logical drive, highlight Accept
and press Enter. If there is space remaining in the arrays, the next logical
drive to be configured appears. To configure another logical drive, repeat
Steps 6 to 9. If the array space has been used up, a list of the existing
logical drives appears. Press any key to continue and respond to the Save
prompt.
11. Initialize the logical drives you have just configured. See "Initializing
Logical Drives" for more information.
Creating Arrays by Using View/Add/Delete Configuration
View/Add/Delete Configuration allows you to add new arrays to an existing
configuration. The new arrays you create can use array spanning. The existing
configuration is left intact, so you can use this selection simply to look at the
current configuration.
1. Choose Configure from the HP NetRAID Express Tools Management
Menu.
2. Choose View/Add/Delete Configuration from the Configure menu. An
array selection window is displayed showing the devices connected to the
