Refer to the HP RAID Device Manager Software online documentation for more information. Initializing an Array When you create a new array in Custom Setup, you are automatically prompted to initialize (format) it. You can also select the Format/Initialize Array option as a separate Custom Setup command. This could be necessary to re-initialize an array that has become corrupted. Here is some additional information on the two initialization methods: • Initialize Array to Zero: (Recommended method) Fills the array with zeroes. This option is faster than a low-level format, but it does not verify the integrity of the disks. • Low-level Format: Performs a low-level SCSI format. This writes a consistent pattern to the disks, checks the disks for defects, and fills the array with zeroes. Low-level formatting can take some time (up to 1 hour) if the disks are large. You cannot abort a low-level format once it has started. Formatting or initializing an array erases all data on the array and cannot be aborted once it has started. If the array contains data you want to keep, be sure to back it up first! Follow these steps to initialize an array: 1 Select Disk Array Operations from the Main Menu. 2 Select Format/Initialize Array from the Disk Array Operations menu. 3 When the list of arrays appears, select the array you want to initialize. 4 Type y to confirm that you want to format the array. 130 English
