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:
: (Recommended method) Fills the array with
• Initialize Array to Zero
zeroes. This option is faster than a low-level format, but it does not
verify the integrity of the disks.
: Performs a low-level SCSI format. This writes a
• Low-level Format
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
2 Select
Format/Initialize Array
3 When the list of arrays appears, select the array you want to
initialize.
4 Type to confirm that you want to format the array.
