The disk array 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 disk array.
2. Note the disk array information, including which drives are used, the
number of drives, RAID Level, etc.
3. Delete the disk array.
4. Create a new disk array using the specifications from the previous disk
array.
5. During the disk array creation process:
• In FastBuild, set the Fast Init feature to ON
• In WebPAM, select Fast or Full Initialization
6. Partition and format the disk array using your PC’s operating system.
See “Appendix A: Partition and Format” on page 113.
