Adaptec SCSI RAID Software Reference Guide
■ When assigning spare drives to a RAID 10 or a RAID 50, the
ACU assigns all the drives in the list to all the arrays within
the RAID 10 (or RAID 50).
■ ACU only creates dedicated hot spares. If the same drive is
assigned to protect multiple arrays, only the last array that
drive is assigned to will be protected.
■ The ACU makes no checks to ensure that the amount of
available space on the specified spare drives is sufficient to
serve as failover for the given array.
Example:
HotspareDrives=1:0:0,1:1:0
The InitializeAll Keyword
InitializeAll is an optional keyword, indicating that all the
drives connected to the controller should be initialized and any
existing arrays deleted before creating a new array. This property
applies to all drives on all channels of the controller. If
InitializeAll is not specified, the value No is used.
Possible values are as follows:
■ Yes—Initialize all drives.
■ No—Do not initialize all drives; only those drives specified with
the Drives property keyword are initialized.
The InitializeAll keyword is both global and position-
independent within a script file. If InitializeAll=Yes appears
in any array definition block within the file, all drives connected to
the controller are initialized and any existing arrays are deleted
before any new arrays are created.
If there is no InitializeAll=Yes property specified anywhere in
the script, the ACU initializes only those drives specified with the
Drives property keyword. See Initializing a Disk Drive on page 13-7
for more details.
Note that it is not necessary to specify InitializeAll=Yes in
more than one array definition block. If both InitializeAll=Yes
and InitializeAll=No are specified within a script file,
regardless of their position within the file, InitializeAll=Yes is
the overriding value.
