Table 5.7 Power Console Plus Logical Drive Menu
Option Description
Initialize This option initializes the selected logical drives. The Power Console Plus utility
enables you to initialize a drive at any time.
Note: Warning: Initializing a drive deletes all its data.
Check Consistency This option verifies the redundancy data in the selected logical drives that use
RAID levels 1, 5, 10, or 50. If a discrepancy is found, MegaRAID assumes that
the data is correct and corrects the parity value. If the failure is a read error on
a data drive, the bad data block is reassigned with the generated data.
Properties This option displays the properties of the selected logical drive. A screen such
as the following appears. You can display each logical drive by selecting the
Previous or Next buttons.
Change Config Through a submenu, this option enables you to change the cache policy, read
policy, write policy, RAID level, and virtual size of the logical drive. You can also
add capacity to the logical drive.
