Chapter 7: Support

If a critical status error message appears on the BIOS startup screen for a
RAID 1, 5, or 10 logical drive, a physical drive has failed or is not responding.
See “Responding to a Critical or Offline Logical Drive” on page 91.
Physical drives cannot be formed into a logical drive
Physical drives must support SATA and be free of media defects in order to
be added to a logical drive. Promise recommends using new identical
physical drives for each logical drive. Also, re-check the data and power
cabling and connections.
The logical drive constantly goes critical or offline during reboot.
This condition may occur when the Master Boot Record (MBR) of one of the
drives has become corrupt or bad. Removing (erasing) the MBR will remedy
any issue related directly to a bad MBR.
To erase the MBR, follow these steps:
1. Backup any important data from the logical drive.
2. Note the logical drive information, including which drives are used, the
number of physical drives, RAID Level, etc.
3. Delete the logical drive.
4. Create a new logical drive using the specifications from the previous
logical drive.
5. During the logical drive creation process:
• In FastBuild, set the Fast Init feature to ON
• In WebPAM, choose Fast or Full Initialization
6. Partition and format the logical drive using your PC’s operating system.
See “Appendix A: Partition and Format” on page 123.
Unable to partition or format logical drive
See “The logical drive constantly goes critical or offline during reboot,”
above.
Cannot rebuild RAID 1, 5, or 10 logical drive
See “The logical drive constantly goes critical or offline during reboot,”
above.
Warning
Before removing the MBR of the drive(s), backup any existing
data. Removal of the MBR of any physical drive permanently
deletes all existing data on the drive.
