What happens if a logical drive goes critical?
This condition is caused by a failed physical drive. Depending on your Event
Notification settings, RAIDXpert will send you and email message and
display a popup message indicating the critical condition.
An amber ! icon will appear over the Logical Drive View and Logical
Drive icons. The Event Log will post a logical drive critical entry.
If a spare drive is available, the logical drive will begin to rebuild
automatically. If there is no spare drive, you must identify the failed physical
drive and replace it.
See "Managing a Critical or Offline Logical Drive" on page 84. Also refer to
your system's User Manual for more information.
