Specifying a hot spare
Escalade ATA RAID Controllers give you the option to specify a hot spare
from one of your available ports (currently shown as offline). Hot spares
should be selected after mirror or RAID 5 creation. Refer to
Creating a disk
array in the 3ware Disk Array Configuration Utility chapter. To specify a hot
spare after the system is booted, physically add the spare drive and click on
the check box next to the available offline port; then click on the
Add Spare
button.
Note:
Hot spare drives must be equal to or larger than the drives
used for the redundant array.
Auto rebuild of a redundant array
If a hot spare is specified and the array degrades, an event notification is gen-
erated and the hot spare dynamically replaces the failed drive in a redundant
array without user intervention. Rebuild will automatically be launched as
background process and an event notification will notify the user when the
rebuild process is complete (if 3DM is running and e-mail notification is
setup).
Rebuilding a redundant array with a hot swap drive
Hot swap allows a user to replace a failed drive in a redundant array while the
system remains up. Hot swap can be used when 24x7 system operation is a
consideration. If multiple drives are faulted in a RAID 10 configuration, the
drives are rebuilt sequentially starting with the lowest port number.
1 Click on the check box of the failed drive.
2 Click the Remove Drive button.
3 Physically remove the failed drive and replace it with a new drive.
4 Click on the check box of the new drive.
5 Click the Add Drive button.
6 Click on the check boxes of at least two members of the array to be
rebuilt. This should include the new drive added in step 3.
7 Click the Rebuild Array button. The rebuild process will run in the
background and an event notification will be sent when it is completed.
Selecting Force Continue on Source Errors
Selecting the Force Continue on Source Errors check box prior to rebuild-
ing the array ensures rebuilds are not terminated if ECC errors are detected on
